Entry giveaway to the Chemistry - Chemical Reactions puzzle. If you have any questions just ask them here.
Chemistry - Chemical Reactions
Don't be shy. Ask questions! There are solvers but there can be more. Ask more questions!
Also I have added some hints yesterday. For those who took a break or gave up before that, a second look might be helpful. Otherwise just ask. I'll try to help to the best of my abilities.
Added more hints for the people with a bad relationship towards chemistry.
I'm failing to find the format for answers that should be right. Chemistry in a non-native language is a lot harder, and it wasn't easy over 15 years ago in "high school" to begin with. ^^

Have you found any answer? For the reaction type questions the format is always (? have to check) "___ reaction"
Comment has been collapsed.
Well, I can tell you what answers I have that aren't correct, but not sure if they are spoilers because it's "close, but no cigar".
Comment has been collapsed.
Concerning the shocking amount of people passing those puzzles at the moment I think you can give some examples here or on one of my older giveaways and we can work over from there. If it is too spoilery you can still delete it afterwards.

"all reactions can be represented as a series of elementary reactions", but Elementary reaction is not correct.
"NaOH ==> Na+ + OH-" could be an exothermic reaction, or <BLEEEEP> (Now correct), neither of which works.
Comment has been collapsed.
Okay, the second one is correct and yea, it was the only answer where I made a typo ..... I have corrected it now so try again. For the first one think about the Law of Mass Action. What does it describe/determine?
Comment has been collapsed.
That was a quote from the wiki of the Law of Mass Action, it tells us that all reactions is a series of elementary reactions. :) I also tried Kinetic reaction, which they also talk about on the wiki.
Comment has been collapsed.
I admit. I didn't use the internet while creating the puzzle. Maybe as a hint: There is some kind of special arrows used for those reactions.
Comment has been collapsed.
As said, it was over 15 years ago I studied chemistry, in Swedish and we might not even have gone over the same things. If I can't research the answers on the internet based on the information available, there's no chance I can solve this. :/
I'm sure it's a fair puzzle, it's just my lack of knowledge on the subject that's the stopping block.
Comment has been collapsed.
I will not rule out making a translation mistake since I used the german termas as basis. But I think I checked them all to atleast ensure that there exists the used term in english for the type of reactions. Tell me if you wish for more help.

Q2, Q3, Q4, Q5, Q6, Q7, Q8, Q9, Q10 solved so far :D
Comment has been collapsed.
Need any help as long as I am still awake?
Comment has been collapsed.
Q3 formar its:
word1 and word2
or
word1 word2
It's not clear for me because "and" is not italic :D
Comment has been collapsed.
the word1 and word2 balance . The whole sentence. So all in all five words with two you have to fill in.
Comment has been collapsed.
Still have problem with Q3. Probably I understand 'balance' word in my polish way ;D Same in Q8. Buuut Q10 solved ;D I've always loved stoichiometry :D
Comment has been collapsed.
Basically what has to be the same on the left and on the right side of the equation. You used it succesfully on Q10. You can use an older giveaway of mine if you think you have the right answer but it doesn't accept the answer.
Comment has been collapsed.
I've got Q1, Q2, Q4, Q7, Q10 solved... May ask you to check the answers for Q5 and Q9? I was sure that I found the answer but ith says they are wrong. Maybe those reaction have more then one name?
Comment has been collapsed.
Q5 is fine for me, but +1 for Q9 :D
Comment has been collapsed.
Q5 should be unique. Granted, there are two other possible solutions which I do not accept since one is already the answer to Q2 and the other to Q6. But most people would assume the searched type with it.
Q9 should be correct. Maybe you have forgotten the prefix.

OK :x Now I know why my puzzle was so easy for you ;D May I ask if everything in stage 3 was fine? I created all images myself and i'm not sure about my chemistry skills :D
Comment has been collapsed.
Stage three is mostly fine although polymers are not my forte. I think Q1, Q2 and Q4 can be solved with a bit of chemistry knowledge. Q5 was interesting since I forgot that one. I found it pretty hard to search for that one but I probably was too complicated. Q3 on the other hand drove me nearly insane since .... you know .... there is another material with the exact same formula. You may put more emphasis on that stretched. After that it was easy but I didn't know how to use it.
And before there arise some kinds of misunderstanding. I only have a PhD in Chemistry. Nothing more.
Comment has been collapsed.
Thanks for this ^^. Q3 was the biggest suprise for me when i learned that those two materials has same formula. :D
Comment has been collapsed.
What about us who did some chemistry back to high school?
I found some answers to reaction types, but were not consistent in naming or definition between sources. Too specific for the non professionals or hobbyists. That's my 1 cent
Comment has been collapsed.
Hm, why did you choose this comment to reply. It relates to the puzzle of Gracee. Other than that all the questions here should be solvable with school knowledge. If you have any questions just ask and we can work from there so the puzzle might become more accessible.
Comment has been collapsed.
Saw that comment again right now: Did it become more accessible after the hints have been added? Or was it still too much grind?
Comment has been collapsed.
I had answered them all before the hints, except for Q9 and Q10. Now I solved it all. I believe the hints help much.
The problem I had was that the information asked were not homogeneous. Meaning that you couldn't find the different kinds of reactions in the same source(eg Wikipedia article about reactions)
TL;DR; Hints help
Comment has been collapsed.
Good to know. Thanks for the feedback. Now I only need to lure people in here.
Comment has been collapsed.
The answer I found for Q5 is wrong also for Q6 (I can't check for Q2 as I've answered it already). And what I found is really typical for organic chemistry as far as I remember...
I found article in english wikipedia describing this type of reaction. Its title is one word and I can't see any prefix... The first line of article is: "__ is a specific type of [some type] reaction in which a species is simultaneously [something] and [something other] to form two different products." (I've edited it to remove spoilers). I think it describing reaction from Q9 very well, but __ is not accepted.
Comment has been collapsed.
Q5 is typically a reaction between a carboxylic acid and an alcohol. It should be easy from here.
Q9: You should concentrate on the oxidation states. From a middle to a higher and lower. You can post what you tried on an older giveaway of mine so I can take a look on it.
Comment has been collapsed.
I've done it...
Comment has been collapsed.
I just assume Q5 and Q9 are working now. Thanks for the input so far. I think the puzzle got a bit more accessible. As for Q3 and Q8. If there are any questions I fear they have to wait till tomorrow since I REALLY need to sleep.
But as an initial hint may be. You shall have the same on the left as on the right.
Comment has been collapsed.
Q5 is done, thank you... But I still can't get Q9. In Q3 and Q8 I understand what is about, but I probably just don't know correct words... But I'm keep trying...
Sleep well!
Comment has been collapsed.
Ok, I found this prefix for Q9... In my humble opinion it should be ommited in a quiz for non-chemists as in most internet sources it described as "hmpfhmpf reaction" without prefix and for not specialists accepted answer sounds like "watery water" or "sweet sugar"
Q3, Q6, Q8 to go, but I'm going to work now...
Should I edit or delete posts from other topic?
Comment has been collapsed.
I will think about omitting the prefix if it appears to be a major hurdle. Yea, it is probably better to edit them although the puzzle seems hard enough already. I wonder how you solved Q10 without being able to get Q3 and Q8. Have fun at work.
Comment has been collapsed.
I remember from school how to balance reactions... But I learned it in polish so I can do practical example and not necessarily answer theoretical question in english ;)
Comment has been collapsed.
Only Q6 left :) I wonder what I've missed... I think I tried with every single type I can imagine...
Comment has been collapsed.
Can I politely suggest this quiz is given a bit of an overhaul. Some people may have a PhD in chemistry, most will not. The fact that there are 30 players, 535 guesses but not one solver suggests this has been made at the (too) hard end of the spectrum. Remember there are about 30 different puzzles in this event and expecting people to have a PhD in 30 different subjects is a bit extreme.
Just as an example - Q2 (which I'm stuck on). I don't know the answer off the top of my head, so I look up "Basic Chemical Reactions". I find four types - synthesis, decomposition, single displacement and double displacement. The only logical choice of those 4 is decomposition, however this doesn't work, most likely because there are ions being formed. Ok, so now what? Is the reaction not considered a "Basic" one in the eyes of many; have I misspelt something; or used a different term (decomposition rather than analysis)? It's really hard to know where to from here. Some guidance would help people keep moving through.
Even the little things like being really clear on formatting will help (e,g. remove the need to put "reaction"). Question 3 could just be word 1 and 2 without the sentence.
For reference, I've completed Q1, 3, 4, 5, 6 and 7 but tbh this is doing my head in (and I loved chemistry back in secondary school - albeit that was quite some years ago).
Some help to make this solvable for a slightly wider population would be appreciated.
Apologies if this seems like a rant.
Comment has been collapsed.
No, suggestions in all form are appreciated but believe me that all of this is chemistry you learn in school. There might come some minor hickups due to difference in experience. As I didn't use the internet for the creation I might use therms like "basic" which might confuse.
For Q2 you should look at the reactants and then it should be easy.
On the formatting I will work over this to make it more accessible.
Other than that there is only one puzzle here and there are other categories where people have up to three or four ITH and they haven't been solved as well so far.
EDIT: As a matter of fact "reaction" isn't needed anywhere.
Comment has been collapsed.
Ok, 2 now solved. Not a term that I saw anywhere when I Googled "Basic" but, granted if I had of used my head instead of Google, I may have been better off. Only 8, 9 and 10 to go.
Comment has been collapsed.
Well, Q8 should be searchable by google and I made the prefix not mandatory anymore so it should be easier. For Q3 think about what is transferred for a change of the oxidation state.
Q10 ..... it is basically math. Just make a sound if you have no idea where to start.
Comment has been collapsed.
All completed now . . . back to the cookware that isn't cookware.
Comment has been collapsed.
Finally, thanks for the help by making the puzzle a bit more accessible (and proving it is solvable). The cookware I assume is another puzzle here O.o
Comment has been collapsed.
Yes, but I've just got that now (you commented to Gracee above in her quiz).
Comment has been collapsed.
Okay, then I think I know what you are talking about. It is irritating especially if you have some knowledge and only see the obvious answer.
Comment has been collapsed.
Yeah, this is one where I think the obvious answer should be accepted . . .

I guess it is to difficult for one who never had chemistry.
Comment has been collapsed.
yea.... I need to take a class and learn how to solve number 10...
Comment has been collapsed.
No, you just need to open the link I posted, copy the equation, remove those things you shall determine and slightly accustom the formattting and then press balance.
EDIT: I actually posted the needed format. You just need to copy it. While two of three balances are easy to handel, getting the third one correct without prior knowledge might prove unjustified difficulty.
Comment has been collapsed.
Having trouble on Q09 mainly. Tried lots of stuff on it, opened 20-30 tabs in wiki/google for a few whole hours and nothing. Maybe a better hint for Q9 would help...
As for Q10 I was seriously ready to say what a joke it is and what symbols these are that they don't even exist, but obviously you required us to delete the useless stuff. Needless to say I could never have done it without an online calculator cause I have no idea how these are calculated... And I still don't... But anyway Q9 for now...
Comment has been collapsed.
Yea, for Q10 I needed to have some placeholders, so you know the format. The online calculator I added later, but maybe I'll give in the hint the alternate formatting so you only need to copy it. It is too difficult after all.
For Q9 so far I couldn't find a good hint which does not tell the answer but I think I found something now. You can take this literally. MnO4^{2-} is "simultaneously acting as reductant or oxidant"
Comment has been collapsed.
And yes I already knew the thing you just said regarding the simultaneous thing... Anyway I finished all with practically no hints from here, I guess that's something... Though I did need the online calculator..
Comment has been collapsed.
Lol found the last one by sheer luck. Never even expected that this would be the answer. lol. Feel free to delete comment didn't even read it.
Comment has been collapsed.
No the comments will stay as I want to have more solvers. Everyone looking here should find some help and also be encouraged to ask for more hints if needed. The goal is to learn something and not to bang your head on the wall.
And yea, balancing these reactions can be overwhelming if you are not familiar with it. It is is basically just math with numbers ranging from 1-30 at most.
Comment has been collapsed.
Can't find Q5 and Q6.
Comment has been collapsed.
Got Q6.
Comment has been collapsed.
Well would have been surprised if not with the hint given. Hint for Q5 does not help? Well, maybe you'll find with the organic variation. Alcohol and Carboxilic Acid
Comment has been collapsed.
That works, thanks.
I hate chemistry. :P
Comment has been collapsed.
The only question I can not solve is Q1.
I haven't added "reaction" to my answers, becasue the other answers for the other questions didn't require the word "reaction" either, so I hope that's not it.
I've read the article about "Law Of Mass" and "Massenwirkungsgesetz" so many times and still can't figure it out.
I think I also have a problem with the general understanding, as I can't see why a reversible reaction (which the LoM describes to my understanding) should be one-sided. I was rather thinking of an exothermic reation, but that has nothing to do with mass.
Inserting all the mentioned reaction types and sub-reaction types found here didn't help either.
Could you give an example of this reaction type?
Comment has been collapsed.
No, reaction is not needed as part of the answer. And sorry with the types and internet search. I made this out of my memory without using external sources. So there may be difference it what i define as type and what not.
As example. There are a lot of them. So that given you one would probably not help much.
NaCl ==> Na+ + Cl- would be an example although (and that may be the biggest hint). The way it is written here is not to 100 % correct. You should stick near the idea of reversible. At some point something will form and stay that way.
Comment has been collapsed.
Can't figure out the answer for Q1, even though it seems so simple.
Comment has been collapsed.
Have you read so far all the comments in the comment section here? Especially the one directly above since it had the same problem. If yes, then I will think how I can make an additional hint.
Comment has been collapsed.
I did, but didn't help much.
Comment has been collapsed.
If the left side and the right side of the equation reach a state where they do not further change with passing time then what is this state called?
Comment has been collapsed.
Got it now. I did think about witing that earlier, but it didn't look like a reaction type to me, so I didn't try. Thanks!
Comment has been collapsed.
Like I said earlier: The word "type" is open to a lot of discussion depending on your sources. For me this was a type as well. It is easier for the following questions I guess.
