18. Identify the following as saturated, unsaturated, or supersaturated
a. 100g of water containing 32g of sodium
nitrate at 40°C.
b. 100g of water containing 30g of sodium chloride
at 80°C.
C. 100g of water containing 45g of potassium
chlorate at 10°C.

the answer is d. 74.02

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.
