16 atoms

Answer 1

In the reactants of the given chemical equation \( C_7H_{16} + O_2 \):

• The compound \( C_7H_{16} \) has 7 carbon (C) atoms.
• The \( O_2 \) molecule contains oxygen atoms and does not have any carbon.

Therefore, the total number of carbon atoms present in the reactants is 7.

The correct response is: 7 atoms.
