The formation reaction of magnesium oxide is as follows:
Mg(s) + 0.5O2(g) → MgO(s)
This reaction can be constructed from the following reactions.
In the blanks before each reaction, add a coefficient that shows how they must be scaled before being added to give the reaction above. If the reversal of a reaction is required, indicate this using a negative sign before the coefficient. For example, if a reaction must be multiplied by 2 and reversed, write "–2."
(a) ___ Mg(s) + 2HCl(aq) → Mg2+(aq) + 2Cl–(aq) + H2(g)
(b) ___ MgO(s) + 2HCl(aq) → Mg2+(aq) + 2Cl–(aq) + H2O(l)
(c) ___ H2(g) + 0.5O2(g) → H2O(l)
