1. An experiment uses a flask (100 g), a balloon (2 g), baking soda (20 g), and vinegar (50 g). What should the mass of the whole system be AFTER the reaction?

The solid xy decomposes into gaseous x and y: xy(s) m x(g) + y(g) kp = 4.1 (at 0 °c) if the reaction is carried out in a 22.4 l container, which initial amounts of x and y will result in the formation of solid xy?
