The correct answer to the following question will be "90.6 kJ/mol".
Explanation:
The total reactant solution will be:
The produced energy will be:
The reaction will be:
⇒ 
Going to look at just the amounts of reactions with the same concentrations, we notice that they're really comparable.
Therefore, the moles generated by NaCl will indeed be:
= 
= 
= 
Now,
= 
= 
= 
Heat energy is released to warm the house

A mixture is an impure substance with the following properties:
- composition is indefinite as they are made up of two or more elements or compounds in any proportion by mass.
- They are able to retain their identities i.e physical properties are maintained.
- Their constituents reacts differently to changed conditions.
- They can easily be separated into constituent by physical methods.
