The following molecular equation represents the reaction that occurs when aqueous solutions of silver(I) nitrate and iron(III) chloride are combined 3AgNO3(aq) + FeCl3(aq) → 3AgCl(s) + Fe(NO3), (aq)
Write the balanced net ionic equation for the reaction.

Explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolytes and  are represented in the form of ions.

The complete ionic equation will be:

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.

  In this equation, and 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 is the correct

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
