Right thanks

The graph was clearly the direct relationship. As temperature increases, pressure increases in a linear fashion. It has nothing to do with an asymptote. Plus, it cannot go negative because the graph shown is only the first quadrant. You overthought the question.

@jhomatas48 so the one that went straight down was right? ayyy!

Edit: never mind didn’t read your post properly

I don’t remember it but I thought it went straight up?

@Bennykor No that would be inverse, it went straight up.

No! It was asking for Ideal gas, you do NOT want pressure to increase. It has to go down.

But since it was an ideal gas shouldn’t the pressure have been decreasing? @Samnicole16 @jhomatas48

@jacobreis It is equal. It is true that one had 2 Hydrogens and the other only had one hydroxide but what they wanted you to say was that a neutral solution has equal amounts of the two ions, making a pH of 7.

and sorry, but a linear line does not make sense

no because they Just asked for the relationship between temperature and pressure. As temperature increases so does pressure

As temp increase the pressure will slowly keep approaching o pressure but never full reach it

@Samnicole16 but I remember the question said ideal gas

Anyone save their answers in their calculator?

Well We’ll find out all the answers 6pm tonight on http://www.kentchemistry.com/RegentsExams/regentsexams.htm

@nickster505 You don’t make any sense… If temperature doubles, pressure doubles. Think about the combined gas law. Pressure over temperature. That is a direct relationship which is a line going up. An inverse relationship would be something like volume and pressure, which makes a sort of hyperbola.

how about the last question of the test what was it and what was answer

3.4

But what you described is a real gas. They added the words ideal gas. That is why the question was confusing for me because I am used to the fact that as temp increases, pressure increases, which would be that linear line going up. But bc it said Ideal gas, I thought about the idea that as temp increases, you need pressure to decrease, which would be a downward slope.

Think about it logically. As volume goes down, there less room for the particles to move around it, and they bump on the walls of their container more. When the volume is large, there is a lot of room and particles don’t bump against the container so much. I chose the linear option because, if nothing else, it paired a small container and low pressure.

Side note- I can’t remember for the h+ acceptor if I put 1 or 2 and it’s making me really nervous
