How many atoms of carbon (C) are present in the reactants of the following chemical equation?

Question

C7H16+O2→CO2+H2O (1 point)
Responses

7 atoms
7 atoms

23 atoms
23 atoms

1 atom
1 atom

16 atoms

Answer 1

In the chemical equation \( C_7H_{16} + O_2 \rightarrow CO_2 + H_2O \), we can look at the reactants:

• \( C_7H_{16} \) contains 7 carbon atoms.
• \( O_2 \) does not contain any carbon atoms.

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

The correct response is 7 atoms.
