Mixture X has (Mg, Zn). Dissolve 16g of X in sufficient quantity of HNO3 solution to give off mg of NO . single reduction product, yielding 65.6 grams of salt mixture. Calculate m

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.
