The change is that the water will freeze to 0 or minus I don’t know as I’m not to sure
This is because it has a full outer valence shell! so there are 8 electrons and that means it doesn't have the urge the gain anymore
Answer:
This is an endothermic reaction with a positive ΔHrxn.
Explanation:
From the question given above, we can see clearly that the energy of the product (Hp) is greater than the energy of the reactant (Hr). This simply means that the reaction is endothermic as the enthalpy change (ΔH) for the reaction will be positive.
Enthalpy change (ΔH) = Heat of product (Hp) – Heat of reactant (Hr)
ΔH = Hp – Hr = positive
NOTE: A reaction with positive enthalphy change (ΔH) is termed endothermic reaction.
