Question

PLEASE HELP DIFFERENCE BETWEEN COMPOUND AND MIXTURE

The chemical properties of a compound are different from the chemical properties of a mixture because:
a. the substances in a compound are chemically joined in a fixed proportion b. the substances in a compound are always composed of at least three different types of atoms
c. mixtures are always homogeneous
d. the properties of a mixture are different from those of the substances from which it is made

Answer 1

A mixture is formed of two substances (molecules, elements, compounds, etc.) that are not chemically bonded. A compound is formed of two substances chemically joined together, so the answer is A.

Answer 2

a. the substances in a compound are chemically joined in a fixed proportion.

Step-by-step explanation:

A compound is defined as a pure substance that has more than one element. Compounds have a fixed composition. This means that a compound always has the same elements with equal percentages by mass. Meanwhile, a mixture is made up of two or more components that are mixed, but are not chemically combined.
