What is the Net Ionic for the two following equations?

Calcium carboante

B) Fe(SCN)^2+

incomplete????

Nope that's how they are given. That's why I was having trouble with them.

the question says 'for the following equations????...where are the equations??..i can't see any equations..

anyway..the first one is calcium carbonate????

so the ionic equation for its formation is;

Ca2+ + CO32- --> CaCO3

whereas Fe(SCN)2+ is;

Fe3+ + SCN- --> Fe(SCN)2+

To find the net ionic equation for a given chemical reaction, you first need to write the balanced molecular equation and then determine the ions that are actually involved in the reaction to form the net ionic equation.

Let's consider the two equations you provided:

A) Calcium Carbonate:
CaCO3(s) → Ca2+(aq) + CO3^2-(aq)

To obtain the net ionic equation, start by balancing the equation and then consider the solubility rules. Calcium carbonate is a solid, so it does not dissociate into ions. Therefore, the net ionic equation is the same as the molecular equation:

Net ionic equation: CaCO3(s) → Ca2+(aq) + CO3^2-(aq)

B) Fe(SCN)2+:
Fe(SCN)2+(aq) → Fe3+(aq) + SCN^-(aq)

In this case, the Fe(SCN)2+ ion is already in ionic form and dissociates into Fe3+ and SCN- ions. Therefore, the net ionic equation is:

Net ionic equation: Fe(SCN)2+(aq) → Fe3+(aq) + SCN^-(aq)

Please note that it is essential to balance the chemical equations correctly and consider the solubility rules to determine which compounds dissociate into ions.
