Question

17. The equation below represents a chemical reaction that occurs in living cells.

CoH1206 + 602 -- 6002 + 6H20 + energy
How many atoms are represented in the reactants of this equation?

Answer 1

36 atoms

Step-by-step explanation:

• C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy

The reactants are in the left side of the equation. First we determine how many atoms are there in the C₆H₁₂O₆ molecule:

• 6 C atoms + 12 H atoms + 6 O atoms = 24 atoms in total

There are two atoms in a O₂ molecule, and there are 6 O₂ molecules in the equation:

• 2 * (6 O atoms) = 12 atoms in total

The total number of atoms in the reactants is

• 24 + 12 = 36 atoms
