Question

Write the aqueous dissolution reaction for the ionic solids below. (Use the lowest possible coefficients. Include states-of-matter under the given conditions in your answer.) (a) Ca(NO3)2

Answer 1

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)
