Chromium, Manganese, and Barium are all examples of metals that can be prepared in a pure form by combining oxides of these elements with reactive metals. When aluminum is chosen as the reactive metal, the process is referred to as the Goldschmidt Process or the Thermite Process.
a) What type of reaction is the Goldschmidt Process?
b) Write the formulas for the common oxides formed by chromium, manganese, and barium.
c) Predict the products formed by each of the three oxides in the Goldschmidt Process, using a balanced chemical equation.
