Which of these represents the correctly balanced equation? HCI + Na2S - H2S + NaCl

4HCI +2Na2S - 2H2S + 4NaCl

2HCI + Na2S - H2S + 2NaCl

2HCI + Na2S - H2S + NaCl

2HCI + Na2S > H2S + 2NaCl

Explanation:

For a balanced chemical equation, the number of moles of atoms on the reaction side must equal the number of moles of atoms on the product side, in accordance with the law of conservation of mass.

The correct answer is:

2HCI + Na2S > H2S + 2NaCl

Since it has equal number of moles of each atom on both sides of the equation: 2 atoms each of hydrogen, chlorine, and sodium on both sides of the equation as well as 1 atom of sulphur on both sides of the equation.
