Answer:
Ca(NO3)2(aq) —> Ca^2+(aq) + 2NO3^-(aq)
Explanation:
Ca(NO3)2 will dissociates in solution as follow:
Ca(NO3)2(aq) —> Ca^2+(aq) + NO3^-(aq)
The above equation can be balance as follow:
There are 2 atoms of NO3 on the left side and 1 atom on the right. It can be balance by putting 2 in front of NO3^- as shown below:
Ca(NO3)2(aq) —> Ca^2+(aq) + 2NO3^-(aq)
