Question

How many atoms of carbon (C) are present in the reactants of the following chemical equation C7H16+ O2→CO2+H2O (1 point) Responses 1 atom 1 atom 16 atoms 16 atoms 23 atoms 23 atoms 7 atoms

Answer 1

To determine the number of carbon (C) atoms present in the reactants of the given chemical equation \( \text{C}_7\text{H}_{16} + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} \), we need to look only at the reactants.

The reactants are:
- \( \text{C}_7\text{H}_{16} \): This molecule contains 7 carbon atoms.
- \( \text{O}_2 \): This molecule does not contain any carbon atoms.

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

So, the correct response is **7 atoms**.
