PLZZZ HELP FAAASSTTT NEED ANSWER IN 5 MINUTES OR LESS What happens when warm air rises?
The global temperature decreases.
The movement creates a difference in air pressure.
Cool air rises with it.
It moves towards the poles.

If warm moist air rises, it will expand and cool so the answer your looking for is B the movement creates a difference in air pressure

yes the other ones are right just show me a pic of ur face cuz u look hot

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.
