Which 0.1 m solution contains an electrolyte?
(1) c6h12o6 (aq) (3) ch3 oh(aq)(2) ch3 cooh(aq) (4) ch3 och3 (aq)

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.
