Problem 92

Balance the equation for the production of acetylene $$\left(\mathrm{C}_{2} \mathrm{H}_{2}\right)$$ from the reaction of calcium carbide with water. If the acetylene is burned to form water and carbon dioxide, how many kilojoules of energy are produced from the complete reaction of 18 g of calcium carbide?
