You are cooking a recipe and it calls for 1/4 a cup of milk. You get your measuring cup out, pour the milk into the 1/4 cup measuring cup, and pour the milk into a mixing bowl.
Does the milk's volume (amount) change from when it was in the measuring cup to the mixing bowl? Answer in a
complete sentence and explain why the volume does or does not change.

No

Explanation:

The volume of the milk in the measuring cup does not change when it is transferred to the mixing bowl.

Volume is the amount of space a body or substance occupies.

It is determined by the amount of matter that is present within a given measurement.

Since the amount of milk was accurately measured out, the volume is maintained when it is transferred to the mixing bowl. The reason why a measuring cup is used is to keep the consistency of the measurement.

answer: the enthalpy of the overall chemical reaction is +87.88 kj or +88 kj.

according to hess's law, the overall enthalpy of a reaction is the difference between the sum of enthalpy values of all the products and the sum of enthalpy values of all the reactants.

δh(reaction) = ∑nδh(products) - ∑nδh(reactants)

δh(reaction) = [δh +δh] - [δh]

δh(reaction) = [1(-287.02) + 1(0) ] - [1(-374.9)] kj = +87.88 kj

here, δh (pcl3) = -287.02 kj, δh(cl2) = 0, δh(pcl5) = -374.9 kj

therefore, enthalpy of the overall reaction is +87.88 kj or +88 kj.
