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 D-0 decomposition of solid mercury(II) oxide (HgO) into liquid mercury and gaseous dioxygen. 2. Suppose 54.0 mL of dioxygen gas are produced by this reaction, at a temperature of 50.0 °C and pressure of exactly 1 atm. Calculate the mass of mercury(II) oxide that must have reacted. Round your answer to 3 significant digits. APR 24 MacBook Air
Much of Earth's history can be unraveled studying sulfur. Sulfur can be used as "geothermometer". The ratios of stable sulfur isotopes change with the temperature of Earth's processes. For example, igneous systems deep inside the Earth occur at very high temperatures, hydrothermal systems occur at intermediate conditions, and sedimentary rock weathering occurs at low temperatures. The composition of stable sulfur isotopes varies across the 1000 degree temperature range. 10. How many peaks would be seen in the mass spectra for such a study? Make a basic sketch (bar chart) a.m.u. vs % natural abundance and label each peak's a.m.u. and % natural abundance.
