Asample of potassium nitrate (49.0 g) is dissolved in 101 g of water at 100 °c, with precautions taken to avoid evaporation of any water. the solution is cooled to 30.0 °c and a small amount of precipitate is observed. this solution is

Saturated solution

Explanation:

Saturated solution is the solution in which no more solute can be dissolved at a particular temperature.

A amount of the solute, potassium nitrate is dissolved at elevated temperature and on cooling, it precipitates. It means that the solution is saturated at that temperature. Precipitation of the solute at lower temperature indicates that the solution is saturated solution.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
