24. an unknown liquid has a mass of 30.6 g 2
and a volume of 52.3 ml. what is the
density of the liquid?

d =  0.585 g/mL

Explanation:

⇒ d = 30.6 g / 52.3 mL

⇒ d = 0.585 g/mL

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.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
