HELP PLEASE ASSIGNMENT IS DUE SOON calculate the molar masses of the following. You must show all work. Show the number of atoms for each element, atomic masses and addition and multiplication symbols. Don not round

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

i think it's letter a.
