Study this chemical reaction: feso4 (aq) + zn (s) --> fe (s) + znso4 (aq) then, write balanced half-reactions describing the oxidation and reduction that happen in this reaction.

oxidation:

reduction:

The oxidation and reduction half reactions are written below.

Explanation:

Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

For the given chemical reaction:

The half reactions for the given reaction follows:

Oxidation half reaction:  

Reduction half reaction:

Hence, the oxidation and reduction half reactions are written above.

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.
