How many moles of HNO3 can be produced from 115 g of NH3? The reactions involved are given below. Assume
each reaction is 100% efficient.
4NH3 + 502 → 4NO + 6H2O
2NO+ O2 → 2NO2
3NO2 + H2O → 2HNO3 + NO

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

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.
