What is the first step in balancing a chemical equation? Rules of balancing chemical equations: 1. write the unbalanced equation 2. count the number of atoms of the same element on reactant and product side of equation 3. make the â¦ number of atoms the same by changing the coefficients, not subscripts 4. balance hydrogen and oxygen last 5. reduce coefficients if possible
BALANCING REDOX EQUATIONS. The following steps may be used to balance oxidationâreduction (redox) equations by the. ionâelectron (halfâreaction) method. While other methods may be successful, none is so. consistently successful as is this particular method. The halfâreactions used in this process will. also be necessary when considering other electrochemical phenomena, thus the usefulness of. halfâreactions goes beyond balancing redox equations. The basic idea of this method is to split a complicated equation into two parts called. halfâreactions.
