Question

ow many atoms of carbon (C) are present in the reactants of the following chemical equation? C7H16+O2→CO2+H2O Responses 1 atom 1 atom - no response given 7 atoms 7 atoms - no response given 16 atoms 16 atoms - no response given 23 atoms 23 atoms - no response given

Answer 1

In the chemical equation \( C_7H_{16} + O_2 \rightarrow CO_2 + H_2O \), the reactant \( C_7H_{16} \) contains 7 carbon (C) atoms. The other reactant, \( O_2 \), does not contain any carbon atoms.

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