The modern view of an electron orbital in an atom can best be described as (ASAP PLS HELP) Question 10 options:

A)

a three-dimensional space that shows the probability where an electron is most likely to be found.

B)

an elliptical path an electron follows around the nucleus.

C)

a spherical shell on the surface of which an electron can be found.

D)

a circular path an electron follows around the nucleus.

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.

it means there are 3 atoms of oxygen
