How do you write a balanced chemical equation for MG hcl?

Answer 1

To write a balanced chemical equation for the reaction between magnesium (Mg) and hydrochloric acid (HCl), you need to first write the chemical equation showing the reactants and products:

Mg + HCl -> MgCl2 + H2

This equation shows that magnesium reacts with hydrochloric acid to form magnesium chloride and hydrogen gas.

To balance the equation, you need to make sure that the number of each type of atom is the same on both sides of the equation. In this case, there is one atom of magnesium on the left side and two atoms of magnesium in magnesium chloride on the right side. To balance the equation, you can add a coefficient of 2 in front of Mg on the left side:

2Mg + 2HCl -> 2MgCl2 + H2

Now the equation is balanced, with two atoms of magnesium, two molecules of hydrochloric acid, two molecules of magnesium chloride, and one molecule of hydrogen gas on both sides of the equation.
