A balloon containing helium gas expands from 230 mL to 860 mL as more helium is added. The expanded balloon contains 3.8 x 10 moles, at constant temperature and pressure.
in the scenario above which of the variables are known?
Obeginning pressure and ending pressure
O ending temperature and ending volume
Obeginning volume and ending quantity of gas
Obeginning moles of gas and beginning temperature

if you're asking what comes out, it's steam.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
