Chemical formular of copper II trioxocarbonate IV
Calcium carbide, CaC2, is the raw material used for the production of acetylene, C2H2, (used in welding torches). Calcium carbide is produced by reacting calcium oxide with carbon, producing carbon monoxide, CO as a by product. When one mole of calcium carbide is formed, 464.8 kj of heat is absorbed,
CaO(s) + 3C(s) = CaC2(s) + CO(g)
a. If the enthalpy change for the reaction is 246.7 kj, what mass of calcium carbide is produced?
b. What is the enthalpy change if 46.7 g of carbon reacts with excess calcium oxide?
c. How many gigajoules of energy is required to consume 1.38x10^5 g calcium oxide?
CaO(s) + 3C(s) = CaC2(s) + CO(g)
