The dissolving of NH4NO3is used in chemical cold packs. If 27.07 g NH4NO3is dissolved in 100.0 mL of water at 25oC, what is the final temperature of the solution?

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.

the ratio of the conjugate base to the acid required to attain the desired ph.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
