Chapter 6, Problem 48AP

The following demonstration takes place in a two-step process: First, solid calcium carbide $\left({\text{CaC}}_2\right)$ reacts with liquid water to produce acetylene gas $\left({\text{C}}_2{\text{H}}_2\right)$ and aqueous calcium hydroxide. Second, the acetylene gas produced is then ignited with a match, causing the combustion reaction of acetylene with oxygen gas to produce gaseous carbon dioxide and gaseous water. Write the balanced equation for each reaction that is occurring.
