why wasnt it 1.4

What did you guys get for 49,50

The base on the reactant side was the acceptor

Was the ideal gas drawing a relationship between pressure and temp. Or pressure and volume?

the H+ accepter was the choice on the reactant side that on the product side had an extra H

I know and I’m scared I picked choice 2

Gay-Lussac’s Law is for ideal gases @nickster505

It was pressure and temp no volume

Okk thank you @jhomatas48

@spf924 pressure and temperature

It was probably temp. I have a terrible memory, sorry. But still, think logically. Low temp is low pressure because the particles are moving much slower.

On all of the graphs I’ve seen, it only curved downwards when there was a relationship between pressure and volume, I haven’t seen anything with temp. And pressure yet

It wasn’t 1.4 because it talked about a decrease in hydronium, which is the same thing as saying a decrease in H^+. This makes it more basic, so it goes up one instead of down. I think? Might be getting details wrong.

yeah ,. I was in the mindset about how to create an ideal gas, by increaseing temp and lowering pressure, rather than thinking about what actually happens

what about the question with 337k what was the answer

was there a fill in question with the answer zero

I think it was 668

For the freezing of 2 grams of water was it -668 or 668. I think its negative since heat of fusion is for melting. So for freezing it would be the opposite sign.

Negative wasn’t nessecary because they just asked the amount lost, implying absolute answer would have been good

What about that question where it asked for a step when lowering the temperate of water. It was q=300(23)(-4.18) right?
