Answer :

because it is a chemical reaction, both sides will need to be balanced, but to show that the number of hydrogen on each side is the same, we should actually calculate how many are on each side

6(CO2)+6(H2O)
on this side the only molecule with hydrogen is H2O, and has 2 hydrogen per molecule, while the reaction uses 6 molecules, giving that side a total of 12 hydrogen atoms.

(C6H12O6)+6(CO2)
on this side, the only molecule with hydrogen is C6H12O6, and it has 12 hydrogen per molecule, and the reaction only produces one molecule, giving this side a total of 12 hydrogen atoms

12 = 12

12 atoms
Lanuel

The number of atoms of hydrogen that are present in the reactants and in the products are 12 atoms respectively.

The Law of Conservation of Mass (LOCOM) states that mass is neither created nor destroyed before and after any chemical reaction.

According to the Law of Conservation of Mass (LOCOM), a properly balanced chemical equation requires that the number of atoms on the reactant side must be equal to the number of atoms on the product side of any chemical reaction.

For the reactant side:

[tex]6H_2 = 6 \times 2 =12\;atoms[/tex]

For the product side:

[tex]H_{12} =12 \times 1 =12\;atoms[/tex]

In conclusion, the number of atoms of hydrogen that are present in the reactants and in the products are 12 atoms respectively.
