How do you balance chemical equations?

using the numbers

                                                     4 Easy steps

1. Write the Unbalanced Chemical Equation

2. Write Down Number of Atoms

3. Add Coefficients To Balance Mass in a Chemical Equation

4. Balance Oxygen and Hydrogen Atoms Last

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.
