Balancing the Equation Ca + H2O = Ca(OH)2 + H2 (and Type of Reaction)

To balance the chemical equation Ca + H2O = Ca(OH)2 + H2 you first must correctly count all of atoms on each side of the chemical equation. When we balance an equation like Calcium + Water our goal is to provide the correct coefficients for each compound. The coefficient is the number that goes in front of the compound. To balance Ca + H2O = Ca(OH)2 + H2 you'll need to be sure to count all of atoms on each side of the chemical equation. Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Calcium + Water. Important tips for balancing chemical equations: Only change the numbers in front of compounds (the coefficients). Never change the numbers after atoms (the subscripts). The number of each atom on both sides of the equation must be the same for the equation to be balanced.
