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.

In 1774, C. Scheele obtained a gas by reacting pyrolusite (MnO2) with sulfuric acid. The gas, which had been obtained that same year by Joseph Priestley by a different method, was an element, A. (a) What is the element isolated by Scheele and Priestley? (b) Element A combines with almost all other elements. For example, with cesium it gives a compound in which the mass percent of A is 19.39%. The element combines with hydrogen to give a compound with a mass percent of element A of 94.12%. Determine the formulas of the cesium and hydrogen compounds. (c) The compounds of cesium and hydrogen with element A react with one another. Write a balanced equation for the reaction.

Sodium hydrogen sulfate is used as a cleaning agent and as a flux (a substance that promotes the fusing of metals and prevents the formation of oxides). One of the ways in which sodium hydrogen sulfate is manufactured is by reacting sodium dichromate, Na2Cr2O7, with sulfuric acid. This process also forms water and chromium(VI) oxide, CrO3. Write a balanced equation for this reaction. (You do not need to include states.) How many kilograms of sodium dichromate, Na2Cr2O7, are necessary to produce 130.4 kg of sodium hydrogen sulfate? How many kilograms of chromium(VI) oxide are formed when 130.4 kg of sodium hydrogen sulfate is made? What is the minimum volume of 18.0 M H2SO4 solution necessary to react with 874.0 kg of sodium dichromate? What is the maximum mass of sodium hydrogen sulfate, NaHSO4, that can be formed from the reaction of 874.0 kg of sodium dichromate with 400.0 L of 18.0 M H2SO4?
5.) Which of the following statements CORRECTLY describes why oxygen is more abundant on earth's crust than nitrogen? XOY. Both of these substances are gases, which were held loosely by the weak gravity of earth during its early formation. XLY. Oxygen is a reactive gas that formed gaseous oxides of nitrogen, carbon, sulfur. XKY. Nitrogen gas is not formed during the big bang nucleosynthesis. XNY. High melting metal oxides were formed when oxygen reacts with the metal, then present on earth.
