That’s what I picked nickstsr (4)

Okk I hope it is correct because it said for an Ideal Gas- But if you look at Gay-Lussac’s graph, it looks completely different

You keep the highest score btw. @acceptmyname

@kimclan1 @J1234567890 what did u guys put for the H+ to OH- ratio??

@kimclan1 what did you pick for that last MC ( the ideal gas and relationship between Pressure/Temp) ?

His is for the opposite (ideal would have pressure go down), now I’m worried it might have been linear instead of exponential though. I believe 2 may have been right then. This always happens to me, I find the test generally easy and mess up on mc especially because I overlook things.

@bhargavaa the nuclear fusion one was combine light nuclei

You are right about the fact that his is opposite with pressure going up. And that it asked for Ideal so yeah , hopefully the one going down is the correct answer. And the reason I didn’t pick the linear is because the linear would eventually reach a negative pressure as temperature continued to increase. That doesn’t make much sense. But the exponential has an aysntope that it gets closer and closer to but never actually reaches a negative value.

@nickster505 I put the one that went straight down because for an ideal gas pressure decreases as temperature increases

I picked the Nuclear Fusion was combine light nuclei btw @Bennykor

For the short answer question that asked for the direction of heat transfer was it from the water to the test tube?

Yes

I’m such an idiot I messed up on the chlorine question. I forgot that it was a gas and I put liquid :frowning:

Also:
Was the pressure question 800 kPa?
Was the joules of heat for the freezing question 668J?

Does anyone remember what the H+ acceptor was for the forward reaction? Was it the choice that was the reactant or the product?

Reactant. I don’t remember the actual base though but it was choice 1 or 2

Last question on the entire test was 3.4?

I think it was choice 1 which was the reactant @nickster505

Ok good because I had the product choice but then X it on the answer sheet and changed it to choice 1 or 2

Yes to both!

Yep @Samnicole16 because a decrease in hydronium concentration means an increase in pH and vice versa
