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.

A major challenge in implementing the “hydrogen economy”is finding a safe, lightweight, and compact way of storinghydrogen for use as a fuel. The hydrides of light metalsare attractive for hydrogen storage because they can store ahigh weight percentage of hydrogen in a small volume. Forexample, NaAlH4 can release 5.6% of its mass as H2 upondecomposing to NaH1s2, Al1s2, and H21g2. NaAlH4 possessesboth covalent bonds, which hold polyatomic anionstogether, and ionic bonds.
