Chapter 3, Problem 7PS

Write balanced chemical equations for the following reactions.

(a) The reaction of aluminum and iron(III) oxide to form iron and aluminum oxide (known as the thermite reaction).

(b) The reaction of carbon and water at high temperature to form a mixture of gaseous CO and H₂ (known as water gas and once used as a fuel).

(c) The reaction of liquid silicon tetrachloride and magnesium forming silicon and magnesium chloride. This is one step in the preparation of ultrapure silicon used in the semiconductor industry
