Let's look at the chemical equation again:
N2 + 3H2 2NH3
This time, you'll use a different method to count the atoms. Multiply the coefficient by the subscript for each atom. For
example, to find the number of hydrogen atoms in 3H2, multiply 3 by 2. Use the following table to organize your work. Fill
in the number of atoms in the reactants and products in the table.
