What are the correct answers?? smart people?? ANYONE??

 

[omg_a]

no recollection. how do you guys remember. my brain is already overflowing eith now irrelevant info.
had a major mind blank on difference between allotropes and isomers-got that question wrong!! also, what was davys acid theory???
and the molar heat of combustion q, was the specific heat capicity of water wrong on the data sheet or is it just me who got a tiny tiny difference in temp???

1. A Esterification. Everyone seems to agree
2. A Biopolymers decompose more easily than traditional synthetic polymers.
3. A Just a guess
4. B Isomers
5. D Acids ionise in solution to for H ions. Everyone else got C though!
6. C
7. B but I have no idea
8. D Atmopshere temperatures
9. A Everyone else at school got D though
10. C High temperature and low pressure
11. B 1- Hexanol
12. C This question really threw me off! I would have said Ammonia and water but it wasn't an option!
13. B I'm not too confident here though...
14. D
15. B I think this is right... not too sure

Can someone please explain question 13?

Everyone's answers vary. Confused...

 

[kow_dude]

How come 11 is (a) 1-hexanol?

1-octanol takes the longest to destect ... coz there's 8 carbons
1-heptanol is the second longest... so shouldnt it be (c) 1-heptanol?

 

[Plebeian]

It detects smaller hydrocarbons more quickly. It detects pentanol first, then hexanol.

 

[The Bograt]

It is the second lightest hydrocarbon
Why is the answer to 9 A?
I got B, and it seems no one else did. The number of moles of O3 was less than that of NO so NO was in excess, and therefore only a max of 0.37 could be achieved..
At least I hope so, since I changed my answer from A to B

Your right about ozone being the limiting factor, but you prolly used the wrong mole of gas volume.

Question 9 is weird. I originally got A through the mole method, using the O3 molecule. When I checked it, I used the NO molecule instead, and got an answer that rounded to 50. As the question states the maximum amount, I changed it to D.

 

[Bridget]

And also question 12. With the pictures there I immediately though ammonia and water but it wasn't an option.
