How is a mixture different from a compound? a. Mixtures have 2 or more components
b. Mixtures are commonly found in nature
c. Solids, liquids, and gases can form mixtures
d. Each substance in a mixture keeps most of its characteristic properties

d. Each substance in a mixture keeps most of its characteristic properties

Explanation:

Compound is formed by the fixed composition of two or more substances while mixture is formed by the different composition of two or more substances.

Compound and mixture are different from each other as each substances in mixture shows its own properties while compounds shows a different new properties.

Hence, the correct answer is "d".

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.

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
