Question

If one molecule of glucose (C6H120) reacts completely with three molecules of oxygen (O2), what is the TOTAL number of atoms

Answer 1

Answer : The total number of atoms in the product are, 36 atoms.

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

When 1 molecule of glucose reacts completely with 3 molecules of oxygen then it react to give 6 molecules of carbon dioxide and 6 molecules of water.

The balanced chemical reaction will be:

$C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O$

There are 3 atoms in carbon dioxide and 3 atoms in water.

Total number of atoms in the product = 6(3) + 6(3) = 36 atoms

Thus, the total number of atoms in the product are, 36 atoms.
