Question

Which is the Net Ionic Equation for:

(remember, the Net Ionic Eq. shows ALL of the PARTICIPANTS)


2FeCl3(aq) + 3Mg(s) ® 3MgCl2(aq) + 2Fe(s)






2Fe3+ (aq) + Cl3- (aq) + 3Mg(s) ® 3Mg3+ (aq) + Cl2- (aq) + 2Fe(s)





2Fe3+ (aq) + 6Cl- (aq) + 3Mg(s) ® 3Mg2+ (aq) + 6Cl- (aq) + 2Fe(s)

Answer 1

Answer:
`2Fe^(3+)(aq)+3Mg(s)\rightarrow 3Mg^(2+)(aq)+2Fe(s)`

Step-by-step explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and are present in an aqueous state and represented in the form of ions.

Net ionic equation : In the net ionic equations, we do not 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.

The complete balanced ionic equation will be:

`2Fe^(3+)(aq)+6Cl^-(aq)+3Mg(s)\rightarrow 3Mg^(2+)(aq)+6Cl^-(aq)+2Fe(s)`

In this equation,
`Cl^-` 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:

`2Fe^(3+)(aq)+3Mg(s)\rightarrow 3Mg^(2+)(aq)+2Fe(s)`
