A piece of metallic indium with a mass of 15.456 g was placed in 49.7 cm of ethanol in a graduated cylinder. The
ethanol level was observed to rise to 51.8 cm. From these
data, the best value one can report for the density of indium is

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.
