The chemical formula for carbonic acid, a compound used in carbonated drinks, is H2CO3. Assume that these symbols represent the three elements of this compound:

Which picture correctly represents carbonic acid?

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.
