The chemical formula of a covalent molecular substance gives the number of atoms per molecule. The formula of a covalent network or ionic compound gives the simplest ratio of atoms/ions in the ...
3 Check whether the equation is balanced by counting the atoms of each element. 4 If necessary, change the number of one of the molecules to make the atoms of at least one element balance.
The big number written in front of a molecule (coefficient) shows how many of that molecule there are. All the atoms in the products come from the atoms in the reactants. The reactants are on the left ...
and 6 oxygen atoms The chemical equation is balanced because the same type and number of atoms are in the reactants and products. Lesson 6.2: Controlling the Amount of Products in a Chemical Reaction ...
