How đồ sộ balance HCL + NAF

To balance any chemical equation following steps are used.

  • Count the number of atoms on the reactant side as well as on the product side. 
  • If a number of an atom on both sides are equal, then it is a balanced equation. If it is not equal, then it is an unbalanced equation, and we have đồ sộ balance that equation.
  • HCl +NaF ⟶ HF + NaCl.
  • In HCl + NaF reaction reactant side contains one hydrogen atom, one chlorine atom, one sodium atom, and one fluorine atom.
  • On the other side, that is, the product side, one hydrogen atom, one chlorine atom, one sodium atom, and one fluorine atom are present.
  • After comparing both the reactant and product sides, we will come đồ sộ the decision that both sides have an equal number of atoms.
  • Number of atom on both reactant and product side is tabulated below.
