Answer :
Answer:
2HNO3(aq) + Mg(OH)2(aq) —> Mg(NO3)2(aq) + 2H2O
Explanation:
At the start of the reaction we have:
HNO3(aq) + Mg(OH)2(aq) —>
During the reaction is the solution the two compounds dissociate as follows:
HNO3 —> H^+ + NO3^-
Mg(OH)2 —> Mg^2+ + OH^-
Combining the above equation we have:
H^+NO3^- + Mg^2+OH^-
Note: Mg will always displace H from solution because Mg is higher than H in the activity series of metals.
In the above equation, there will be a double displacement or replacement as shown below:
H^+NO3^- + Mg^2+OH^- —> Mg^2+NO3^- + H^+OH^-
Now writing the elemental equation, we have
2HNO3(aq) + Mg(OH)2(aq) —> Mg(NO3)2(aq) + 2H2O
