Question

Guidelines for balancing a chemical reaction (again, take notes if needed).
• Use coefficients only. Never change the subscripts to make it balance.
• Balancing the atoms in the most complex substances first.
• Save for last the atoms of simplest formulas (like pure elements).
. There is a bit of trial and error, so do not worry if you have to erase.
• Always check that it is balanced by comparing the number of atoms of each element of either side of the equation.
H₂ + O₂H₂O
Begin by balancing oxygen. Enter a coefficient in front of water to balance only the oxygen.
