At STP the volume of HCl that will result from the reaction of 0.680 L of H2 and 0.750 L of Cl2 is . H2(g) + Cl2(g) 2 HCl(g)

pd: I will mark best answer.

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?
