Which property describes a mixture? check all that apply. it can be separated by physical methods. it has a single chemical composition. it can appear different from different sources. it cannot be described by a chemical symbol or formula. it cannot have more than one state of matter.

Answers are:

1) It can be separated by physical methods.

2) It can appear different from different sources.

3) It cannot be described by a chemical symbol or formula.

Mixture is composed of at least two substances.

Pure substance is made of only one type of atom (element) or only one type of molecule (compound), mixtures and solutions are made from two or more types of pure substances.

Mixtures can be separeted y physical means, while compounds cannot.

There is a definite recipe to make each mixture, because composition of mixture can vary.

Explanation:

When two or more substances are mixed together which are not chemically bonded together then it results in the formation of a mixture.

A mixture can be separated by physical means since it is not chemically bonded.

Therefore, properties that describe a mixture are as follows.

a polar bond is formed when electrons are shared unevenly between atoms

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
