Write balanced net ionic equations for the reactions that occur in each of the following cases. identify the spectator ion or ions in each reaction. cr2(so4)3(aq)+(nh4)2co3(aq)−→ cr2(so4)3(aq)+(nh4)2co3(aq)→ ba(no3)2(aq)+k2so4(aq)−→ ba(no3)2(aq)+k2so4(aq)→ fe(no3)2(aq)+koh(aq)−→

Answer :

(a) The net ionic equation will be,

The spectator ions are,

(b) The net ionic equation will be,

The spectator ions are,

(c) The net ionic equation will be,

The spectator ions are,

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

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 given balanced ionic equation will be,

The ionic equation in separated aqueous solution will be,

In this equation, are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

(b) The given balanced ionic equation will be,

The ionic equation in separated aqueous solution will be,

In this equation, are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

(c) The given balanced ionic equation will be,

The ionic equation in separated aqueous solution will be,

In this equation, are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

a corroding iron, if that's one of your choices
