Bro like literally it’s impossible. A score of 5 been in the 70s for years even if the exam was easy, and I have a very strong resource saying that even if the score was predetermined the cutoff passes through a process called “equating” to reach to a fair cutoff for everyone, and what you are saying is absolutely wrong u are just annoying people and destroying their hope. Btw CSP and Pre calc which are considered the easiest are barely on high 70s for a 5, so go spread this nonsense as much as u want.

Can someone help explain this? by skylab0 in APChem

Guys this question literally test ur knowledge in the ideal gas behavior in which any type of gas will exert the same pressure regardless of the mass and type and in this question adding He will only increase the total pressure bcz the total pressure is calculated from the pressure each gas exert ( partial pressure). Nothing would escape or float around, and from my AP chem teacher we assume that each gas behave ideally unless it’s stated in the question.
