Balance the Equation H2 + Cl2 = HCl (and Type of Reaction)

To balance the chemical equation H2 + Cl2 = HCl you first must correctly count all of atoms on each side of the chemical equation. When we balance an equation like Hydrogen gas + Chlorine gas 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 H2 + Cl2 = HCl you&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 Hydrogen gas + Chlorine gas. 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.
