When the following two solutions are mixed:
K2CO3(aq) + Fe(NO3)3(aq)
the mixture contains the ions listed below.
1. Sort these species into spectator ions and ions that react.
O NO3^-(aq)
O Fe^3+(aq)
O CO3^2-(aq)
O K+(aq)

the two spectator ions are;  K(+) and NO3(-)

Explanation:

First off, let's write out the balanced chemical equation for the reaction;

3K2CO3(aq) +2Fe(NO3)3(aq) > 6KNO3(aq) + Fe2(CO3)3(s)

In order to identify which ions are spectators, we have to break the equation down to an ionic equation. This is done by splitting all aqueous compounds into ions while leaving the solids, liquids as they are.

We have;

K(+) + CO3(2-) + Fe(3+) + NO3(-) ---> K(+) + NO3(-) + Fe2(CO3)3(s)

Spectators ions are pretty much those ions that do not undergo a change in the reaction. Spectator ions always have the same number of moles and charge in both sides of the reaction.

Upon observing the ionic equation, we can tell that the two spectator ions are;  K(+) and NO3(-)

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.
