Answer:
Honey is an homogeneous mixture
Salsa is an heterogeneous mixture
Explanation:
Honey is a sweet uniformly colored liquid that can be of a dark variety or of clear golden color. Honey is made in nature by bees from flower nectar and is used as a food additive or sweetener
Honey is a homogeneous mixture because the concentration of the components of honey are uniformly distributed throughout the mixture. Every portion has the same concentration of components
Salsa is a sauce made by mixing chopped tomatoes, onions, chilies, lime juice and seasoning and therefore consists of both solid and liquid components mixed in varying proportion such that part will have continuous that comes in between different types of solid and no two parts have exactly the same composition
Therefore, salsa is an heterogenous liquid.
Answer:
most endothermic reactions
Explanation:
In endothermic reactions, the entropy of the environment decreases.
The entropy is the measure of the disorder of a specific system.
An endothermic reaction is every chemical reaction in which energy is absorbed.
In a comparison of an endodermic reaction in which energy is released in light or heat form.

Answer:
Explanation:
Dissolving is when a soluble solute is added to a solvent. The solvent surrounds the solutes and makes a solution of it. The process of dissolving is known as dissolution. For a substance to be able to dissolve in a solvent, they must both have similar properties. It is generally known that like dissolves like. Polar solvents will dissolve polar solutes and vice versa.
Boiling can reverse dissolution process in that, the solvent can reach its boiling point and it wil begin to give out vapours. As more vapours are release, the solutes begin to aggregate and form back.
