Before the use of electric lights, miners used to use carbide lamps. A carbide lamp produces acetylene gas, a common welding gas that produces a bright flame. If the acetylene burns at a rate of 650 grams per hour, and miners are underground for periods of 5 hours at a time, how much calcium carbide should the miner bring with him?(5 points) The equation for a calcium carbide lamp is given below: 

CaC2(s) + 2H20(1) - C2H2(g) + Ca(OH)2(aq)
