Use the periodic table to determine the amount of copper and aluminum nitrate formed in the reaction. Type the correct answer in the box. Express your answer to the correct number of significant figures. 2Al +2Cu(NO₃)₂⇒ 3Cu +2Al(NO₃)₃

In the reaction, ___ moles of Cu and ___ moles of Al(NO3)3 are formed.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
