HELP WILL GIVE BRAINLIEST What is heat energy indirectly measured by?

A. temperature

B. recording the motion of molecules

C. kinetics

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.
