When dissolving a solid or liquid, as the temperature of the solvent increases, the rate of dissolution?
A. increases.
B. decreases.
C. stays the same.
D. either increases or decreases, depending upon the liquid.

D

Explanation:  As temperature increases, the solubility of a solid or liquid can increase or decrease depending on whether the dissolution reaction is exothermic or endothermic. In endothermic reactions, the net energy from the bonds breaking and forming results in heat energy being absorbed when the solute dissolves in solution.

explanation:

2b2t

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.
