How do you write a balanced chemical equation MG with hcl? Single replacement.
To write a balanced chemical equation for the reaction between magnesium (Mg) and hydrochloric acid (HCl) in a single replacement reaction, you first need to write the unbalanced equation:
Mg + HCl → MgCl2 + H2
Now, balance the equation by ensuring that the number of each type of atom is the same on both sides of the equation:
Mg + 2HCl → MgCl2 + H2
This is the balanced chemical equation for the reaction of magnesium with hydrochloric acid in a single replacement reaction.
