4nh3+5o2--> 4no+6h20 what is the total number of moles of h2o produced when 12 mole of nh3 is completely consumed?

18 mol  

Step-by-step explanation:

Step 1. Balanced equation

4NH₃ + 5O₂ ⟶ 4NO + 6H₂O

Step 2. Calculation:

You want to convert moles of NH₃ to moles of H₂O

The molar ratio is 6 mol H₂O:4 mol NH₃

Moles of H₂O = 12 mol NH₃ × (6 mol H₂O/4 mol NH₃)

Moles of H₂O = 18 mol H₂O

The reaction will form 18 mol of H₂O.

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.

50.23 i believe is correct but don't quote me on that.
