Answer:
The balanced equation of H2 + Cl2 —-> HCl is 2H2 + 2Cl2 —-> 2HCl.
Explanation:
In a chemical reaction, the number of atoms of each element must be the same on both sides of the equation. In this case, there are two atoms of hydrogen on the left side and two atoms of chlorine. On the right side, there is one atom of hydrogen and one atom of chlorine. In order to balance the equation, we must add another chlorine atom to the right side so that there are two atoms of chlorine on both sides of the equation. The final balanced equation is 2H2 + 2Cl2 —-> 2HCl.
