The composition of hydrogen selenide (H2Se) can be determined by heating
tin (Sn) in a measured volume of the gas. The hydrogen selenide is
decomposed, producing solid tin selenide (SnSe) and hydrogen gas. If the
temperature and pressure are unchanged, the gas volume when the
decomposition is over is the same as it was to begin with.
Write a balanced chemical equation for the reaction between hydrogen
selenide and tin (including physical states).
Explain briefly why your equation accounts for the fact that the gas
volume is unchanged.
