Answer: D

Explanation:

Because in the reactant side there's/re 1 Ca atom as well as in the product side

                                                                 2 Cl atoms as well as in the product side

                                                                 2 H atoms as well as in in the product side

                                                                 1 C atom as well as in the product side

                                                                 3 O atoms as well as in the product side

Hope this help^^

The chemical equation occurs whenever the number of atoms included in the side of the reaction equals the atomic mass involved inside the product's side. Following are calculations to the balanced reaction:

Sides of the reactant:

  • [tex]\bold{1 \ mole\ Ca, 2\ moles \ Cl^{-}, 2\ moles\ H, and\ 1\ mole \ CO_{3}^{2-} }[/tex]are present on the reactant's side.

Calculating the product side:

  • [tex]\bold{1 \ mole\ Ca, 2\ moles \ Cl^{-}, 2\ moles\ H, and\ 1\ mole \ CO_{3}^{2-} }[/tex] are present on the reactant's side.
  • Since the number of moles of element atoms/ions on both the reactants and the sides of the product of the given interaction is the same.

Therefore, the answer is "option D".
