The following demonstration takes place in a two-step process: First, solid calcium carbide ( CaC 2 ) reacts with liquid water to produce acetylene gas ( C 2 H 2 ) 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.
