When a solution of magnesium nitrate is mixed with a solution of sodium phosphate, the solid that forms is magnesium phosphate. select the equation that represents the complete ionic equation. a. mg(no3)2(aq) + na2po4(aq)  mgpo4(s) + nano3(aq) b. mg2+(aq) + po43-(aq)  mgpo4(s) c. 3mg(no3)2(aq) + 2na3po4(aq)  mg3(po4)2(s) + 6nano3(aq) d. 3mg2+(aq) + 2po43-(aq)  mg3(po4)2(s) e. 3mg2+(aq)+6no3-(aq) + 6na+(aq) + 2po43-(aq) mg3(po4)2(s)+6no3-(aq)+ 6na+(aq)

Answer : The correct option is, (E)

Explanation :

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The balanced molecular equation will be,

The complete ionic equation in separated aqueous solution will be,

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

c. is the answer
