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

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)
