Balanced Chemical Equation:
MgO(s) + 2HCl(aq) → MgCl₂(aq) + H₂O(l)
Explanation:
- Reactants: Magnesium Oxide (MgO) in its solid state (s) and Hydrochloric Acid (HCl) in aqueous solution (aq).
- Products: Magnesium Chloride (MgCl₂) in aqueous solution (aq) and Water (H₂O) in its liquid state (l).
- Balancing: The equation is balanced to ensure the number of atoms of each element is the same on both sides. There is 1 magnesium atom, 2 oxygen atoms, and 2 hydrogen atoms on the reactant side. The product side has 1 magnesium atom, 2 chlorine atoms, 1 hydrogen atom, and 1 oxygen atom. The equation is balanced by using a coefficient of 2 before HCl.
