An explanation of how to balance the equation Fe + O2 = Fe2O3 and the correct coefficients for each substance in the equation. • To balance Fe + O2 = Fe2O3 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 Iron + Oxygen gas. • • Video Tutorial: Balancing Chemical Equations • • Balancing Chemical Equations (how-to,... • • 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. • • A big reason we balance equations is to find the ratios between different substances in the chemical reaction. The coefficients, the big numbers in front of compounds, tell us the ratios. These are often thought of as mole ratios. • Understanding why we balance equations helps you organize your thinking efficiently and makes learning faster and more memorable. The two big reasons for balancing equations. First is so that they obey the Law of Conservation of Mass. Second is so we can use the coefficients as ratios between products and reactants.
