Which net ionic equation would match this description of a chemical reaction: when a
solution of magnesium nitrate is mixed with a solution of sodium phosphate, the solid that forms is magnesium phosphate.

a. mg(no3)2(aq) + na2po4(aq) à mgpo4(s) + nano3(aq)

b. mg2+(aq) + po43-(aq) à mgpo4(s)

c. 3mg(no3)2(aq) + 2na3po4(aq) à mg3(po4)2(s) + 6nano3(aq)

d. 3mg2+(aq) + 2po43- à mg3(po4)2(s)

e. 3mg2+(aq) + 6no3-(aq) + 6na+(aq) + 2po43- àmg3(po4)2(s) + 6no3-(aq) + 6na+(aq)

it shuld be d correct?

Explanation:

, are strong electrolytes. Hence they are fully ionized in aqueous solution.

is a sparingly soluble salt. Hence it remains undissociated in aqueous solution.

So, total ionic equation:

Net ionic equation is written by omitting spectator ions from total ionic equation.

Here, and ions are spectator ions as they remain present on both side of total ionic equation.

So, net ionic equation:

So, option (d) is correct.

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
