Question

Mixtures are different from compounds because compounds have to be:
A. physically separated
b. chemically separated
c. both a and b

Answer 1

a compound is when the atoms of different elements are chemically held to one another. a mixture is a substance that has two or more different materials in such a way that no chemical reaction occurs.
A mixture can usually be separated back into its original components, a compound can not.
Example of mixture: salt water, because you can evaporate the water and get the salt. it is not chemically held together.
