O GASES Solving for a gaseous reactant Jacqueline v The great French chemist Antoine Lavoisier discovered the Law of Conservation of Mass in part by doing a famous experiment in 1775. In this experiment Lavoisier found that mercury(II) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas. 1. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid mercury(II) oxide (HgO) into liquid mercury and gaseous dioxygen. 2. Suppose 25.0 mL of dioxygen gas are produced by this reaction, at a temperature of 70.0 °C and pressure of exactly 1 atm. Calculate the mass of mercury(II) oxide that must have reacted.
