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?
you have an incorrect formula for magnesium chloride. Yes, it is in solution, it is moderately soluble. (53g per 100 g water).
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.
