5.3 liters of sulfur vapor, S8(g), at 558.7°C and 3.8 atm is burned in excess pure oxygen gas to give sulfur dioxide gas measured at the same temperature and pressure. What mass (in g) of sulfur dioxide gas is obtained? Enter to 1 decimal place.
Suppose that you are going to collect H2 gas produced from the reaction of an acid with a metal such as zinc. This reaction gives off heat, so the tem perature of the solution will increase as the reaction proceeds.
