A sample of magnesium metal reacts with hydrochloric acid solution to produce magnsesium chloride solution and hydrogen gas.
a)write a balanced chemical equation for this reaction and include phase designations.
The phase designations would be s for solid, aq for aqueous, and g for gas.
How do you do this?
Mg(s) +HCL(aq) --> MgCl(aq) + H2(g)
Would MgCl be aqueous?

I have to point out, in an aqueous solution, if the Mg is in excess, you have this reaction:
Mg(s)+ H2O(l)>>Mg(OH)2(s) + H2
Magnesium hydroxide precipates, as it has very low solubility in water.

To determine whether MgCl is aqueous or not, you need to understand the solubility of magnesium chloride in water. Magnesium chloride is highly soluble in water, so when it dissolves in water, it dissociates into its ions, Mg²⁺ and Cl⁻.
Therefore, in the balanced chemical equation:
Mg(s) + HCl(aq) → MgCl(aq) + H₂(g)
MgCl is aqueous because it exists as ions in the solution. The "(aq)" designation indicates that the substance is dissolved in water.
