REALLY NEED HELP Perform each of the following unit conversions using the conversion factors given below: 1.000 atm = 760.0 mmHg = 101.325 kPa 1.429 atm = mmHg 9,361 Pa = kPa = mmHg 725 mmHg = atm = kPa

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.

the answer is c. nacl

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
