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(11) oxide (HgO) into liquid mercury and gaseous dioxygen 0 2. Suppose 16.0 mL of dioxygen gas are produced by this reaction, at a temperature of 120.0 C and pressure of exactly 1 atm. Calculate the mass of mercury(II) oxide that must have reacted. Be sure your answer has the correct number of significant digits. 0. 0-0 Cac 8 X O
