Question

How do you complete the equation `Mg(OH)_2(s) + 2HCl(aq) -> __(aq) + 2H_2O(l)`?

Answer 1

`Mg(OH)_2(s) + 2HCl(aq)rarrMgCl_2(aq) + H_2O(l)`

Explanation:

This is simply an acid-base reaction, which we may represent by the balanced net ionic reaction:

`Mg(OH)_2(s) + 2H^(+) rarr Mg^(2+) + 2H_2O(l)`

Charge is conserved, as well as mass........What does this mean?
