THIS IS MAINLY A QUESTION FOR GUYS AGES 15+ Hey, My name is Karina. 15. S1NGLE
I have a question, and you will get brainliest if it makes sense.
How in world tarnation, if you were a female, would you tell your friend you have feelings for him, and him vice versa, but he's dating someone?
Just asking. Cause I've had this happen before, and then I let it go. It's kinda like a quiz.
Love y'all
Karina :)

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.
