Balance the equation for the production of acetylene

Solution:Step-1Here we will have to balance the chemical equation for the formation of acetylene from CaC (s) 2and H O2l), the reaction will beCaC (s) + H O (l) C H (g) + Ca (OH) (s) 2 2 2 2 2Now we have to balance the above equation.Here total number of H atoms in reactant is 2, where as in product it is 4. In order to balance thetotal number of H -atoms in both the sides , multiply 2 with H O .Hence the equati2 will beCaC (s) + 2H O (l) C H (g) + Ca (OH) (s) 2 2 2 2 2Step-2If the acetylene gas burned it will form H O and CO ,2
