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. Only the species which are present in aqueous state dissociate.

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.

(a)

The balanced molecular equation will be,

$2HClO_4_{(aq)}+Na_2CO_3_{(aq)}\rightarrow H_2O_{(l)}+CO_2_{(g)}+2NaClO_4_{(aq)}$

The complete ionic equation in separated aqueous solution will be,

$2H^+_{(aq)}+2ClO_4^-_{(aq)}+2Na^+_{(aq)}+CO_3^{2-}_{(aq)}\rightarrow H_2O_{(l)}+CO_2_{(g)}+2Na^+_{(aq)}+2ClO_4^{-}_{(aq)}$

In this equation the species present are, $2Na^+\text{ and }2ClO_4^-$ are the spectator ions.

Hence, the net ionic equation contains specie is

$2H^+_{(aq)}+CO_3^{2-}_{(aq)}\rightarrow H_2O_{(l)}+CO_2_{(g)}$

(b)

The balanced molecular equation will be,

$NH_4Cl_{(aq)}+NaOH_{(aq)}\rightarrow H_2O_{(l)}+NH_3_{(g)}+NaCl_{(aq)}$

The complete ionic equation in separated aqueous solution will be,

$NH_4^+_{(aq)}+Cl^-_{(aq)}+Na^+_{(aq)}+OH^{-}_{(aq)}\rightarrow H_2O_{(l)}+NH_3_{(g)}+Na^+_{(aq)}+Cl^{-}_{(aq)}$

In this equation the species present are, $Na^+\text{ and }Cl^-$ are the spectator ions.

Hence, the net ionic equation contains specie is

$NH_4^+_{(aq)}+OH^{-}_{(aq)}\rightarrow H_2O_{(l)}+NH_3_{(g)}$

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
