How many moles of ammonia would be required to react exactly with 0.870 moles of copper(II) oxide in the following chemical reaction? 2NH3(g)+3CuO(s)=3Cu(s)+N2(g)+3H2O(g )

Simple Stoich Question

Explanation:

0.870 moles divided by 3 mol ratio of CuO, multiplied by 2 mol ratio of NH3 (ammonia)

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.
