Question

Write the net ionic equation for the reaction of calcium nitrate and sodium phosphate

Answer 1

I assume these are aqueous solutions.
First write and balance the molecular equation.
3Ca(NO3)2(aq) + 2Na3PO4(aq) ==> Ca3(PO4)2(s) + 6NaNO3

Then break these up into ions following these rules.
a. pure liquids are written as molecules.
b. gases are written as molecules
c. solids are written as molecules.
d. All others are written as ions.

3Ca^2+(aq) + 6NO3^-(aq) + 6Na^+(aq) + 2PO4^3-(aq) ==> Ca3(PO4)2(s) + 6Na^+(aq) + 6NO3^-(aq)

The above is the complete ionic equation. To change this to the net ionic equation, we cancel any ions that appear on both sides. So we can cancel 6Na^+(aq) and 6NO3^-(aq) which leaves us with
3Ca^2+(aq) + 2PO4^2-(aq) ==> Ca3(PO4)2(s)

Answer 2

Write a balanced net ionic equation for the reaction between calcium ions and sodium carbonate

Answer 3

Calcium nitrate + sodium _______ -> _______ hydroxide + _______

Answer 4

none

Answer 5

What type of Reaction is this? Not a redox because none of the oxidation numbers are changing, not an acid/base reaction... Any help here?

Answer 6

It probably won't help anymore but it's a double replacement reaction

Answer 7

moan*

Answer 8

this was almost perfect except the phosphate has a 3- charge not 2-
