Answer

Explanation:

Step1: Calculate O - atoms in CO₂

Each CO₂ has 2 O - atoms. With 5 CO₂ molecules, the number of O - atoms from CO₂ is $5\times2 = 10$.

Step2: Calculate O - atoms in H₂O

Each H₂O has 1 O - atom. With 10 H₂O molecules, the number of O - atoms from H₂O is $10\times1=10$.

Step3: Total O - atoms

The total number of O - atoms in the reactants (which is equal to the number of O - atoms in the products due to conservation of mass) is $10 + 10=20$.

Answer:

C. 20 oxygen atoms
