The equation for the formation of water from its elements, h2(g) + o2(g)  h2o(l), can be "balanced" by changing the formula of the product to h2o2. explain why this is incorrect

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?
