Answer 1

To find the number of carbon (C) atoms in the reactants of the given chemical equation:

The reactants are:

• \(2 \text{C}6\text{H}{10}\)
• \(17 \text{O}_2\)

Each \( \text{C}6\text{H}{10} \) molecule contains 6 carbon atoms.

So for \(2 \text{C}6\text{H}{10}\): \[ 2 \times 6 = 12 \text{ carbon atoms} \]

Thus, in the reactants, there are 12 atoms of carbon (C).

So the correct response is:

12 atoms
