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(-)

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
