Answer:

The correct option is 18

Explanation:

There are two reactant specie in the equation; carbon dioxide (CO₂) and water (H₂O). From the equation, there are 6 molecules of CO₂, hence the number of oxygen atoms from CO₂ is <em>6 × 2 = 12</em> and there are also 6 molecules of H₂O, hence the number of oxygen atoms from H₂O is <em>6 × 1 = 6</em>.

The total number of oxygen atoms in the reactants is therefore 12 + 6 = 18

Explain why is it better to use images on hazard labels, rather than words
