Acetylene, C₂H₂ (boiling point = –84°C), is produced by the reaction of solid calcium carbide, CaC₂, and liquid water. Calcium hydroxide solution is the other product of the reaction. 127 kJ of energy is transferred to the atmosphere per mole of acetylene reacted. What mass of calcium carbide in kilograms and volume of water in gallons are needed to produce 125 cubic feet of acetylene at 17°C and 1.0 bar? What quantity of energy in megajoules will be transferred in the process?

Before small batteries were available, carbide lamps were used for bicycle lights. Acetylene gas, C2H2, and solid calcium hydroxide were formed by the reaction of calcium carbide, CaC2, with water. The ignition of the acetylene gas provided the light. Currently, the same lamps are used by some cavers, and calcium carbide is used to produce acetylene for carbide cannons. What volume (in L) of C2H2 at 1.009 atm and 13.6°C is formed by the reaction of 15.18 g of CaC2...
