Which of the following is not a form of energy?
o a) light
ob) pressure
oc) heat
od) electricity

pressure

Explanation:

you have to use energy to apply pressure, so i mean

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.

fe 55.85 g/mol and h2o 18.02 g/mol.
