For Part A: The spectator ions are $Fe^{3+}\text{ and }CO_3^{2-}$ and the ions that react are $K^+\text{ and }NO_3^-$

For Part B: The net ionic equation is given below.

Explanation:

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

For Part A:

The chemical equation for the reaction of iron (III) nitrate and potassium carbonate is given as:

$2Fe(NO_3)_3(aq.)+3K_2CO_3(aq.)\rightarrow 6KNO_3(aq.) + Fe_2(CO_3)_3(s)$

Ionic form of the above equation follows:

$2Fe^{3+}(aq.)+2NO_3^-(aq.)+3K^+(aq.)+3CO_3^{2-}(aq.)\rightarrow 6K^+(aq.)+6NO_3^+(aq.)+Fe_2(CO_3)_3(s)$

As, potassium and nitrate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

$2Fe^{3+}(aq.)+CO_3^{2-}(aq.)\rightarrow Fe_2(CO_3)_3(s)$

Hence, the spectator ions are $Fe^{3+}\text{ and }CO_3^{2-}$ and the ions that react are $K^+\text{ and }NO_3^-$

For Part B:

The chemical equation for the reaction of sulfuric acid and barium hydroxide is given as:

$Ba(OH)_2(aq.)+H_2SO_4(aq.)\rightarrow BaSO_4(s)+2H_2O(l)$

Ionic form of the above equation follows:

$Ba^{2+}(aq.)+2OH^-(aq.)+2H^+(aq.)+SO_4^{2-}(aq.)\rightarrow BaSO_4(s)+2H_2O(l)$

All the ions are present in this reaction. Thus, no ion is considered as spectator ions.

Answer from: Quest

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is $1s^{2}2s^{2}2p^{6}3s^{1}$ and electronic configuration of phosphorous is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{3}$ .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

$3na + p \rightarrow na_{3}p$

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

Electrons are transferred from atoms of to atoms of this transfer makes the sodium atoms and the
