help i really really need it!:) thanks.

Give an example of a single transformation of energy and an example of multiple transformations.

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'm pretty sure its b i might be wrong though!
