Identify the states of matter of each compound in the equation. By convention a net ionic equation is written with the smallest possible integer values for the stoichiometric coefficients. Ensure that the same number of each type of atom appears on both sides of the equation Write the state symbol after each chemical symbol.
Balance the complete molecular equation.
CaC 2 s 2 H 2 Og --- C 2 H 2 g CaOH 2 g. Be sure to cancel out the substance produced in the first step and used up in the second step. Chemical equations are balanced for mass and charge meaning the number. Determine the physical states of all reactants and products.
