What are the products formed when magnesium reacts with hydrochloric acid?

When magnesium reacts with hydrochloric acid, the products formed are magnesium chloride and hydrogen gas.

To determine the products formed in a chemical reaction, you need to understand the concept of chemical equations and the reaction types involved. In this case, it is a single displacement or redox reaction.

Here is the balanced chemical equation for the reaction between magnesium and hydrochloric acid:

Mg + 2HCl -> MgCl2 + H2

In this equation, Mg represents magnesium, HCl represents hydrochloric acid, MgCl2 represents magnesium chloride, and H2 represents hydrogen gas. The numbers in front of each compound or element represent the stoichiometric coefficients, indicating the relative quantities of each substance involved in the reaction.

To balance the equation, the number of atoms on each side of the equation must be equal. In this case, there is one magnesium atom on the left side and one on the right side, two chlorine atoms on the right side, and two hydrogen atoms on the right side.

By understanding the reaction type and balancing the equation, we can conclude that when magnesium reacts with hydrochloric acid, magnesium chloride and hydrogen gas are the products formed.
