2

Each circle represents an atom and each different color represents a different kind of atom. If two atoms are touching then they are bonded together as a compound. 

Which of the following describes the contents of the given image?

Possible Answers:

Mixture of Compounds

Mixture of Compounds and Elements

Compound

Element

Mixture of Elements

Correct answer:

Mixture of Elements

Explanation:

This is a mixture of elements. Each different circle is one type of element. Because there are two different colors and none of them form compounds that means this is a mixture of two different elements.

Example Question #42 : Compounds

3

Each circle represents an atom and each different color represents a different kind of atom. If two atoms are touching then they are bonded together as a compound.

Mixture of Elements

Correct answer:

Mixture of Compounds

Explanation:

There are two different molecules in this picture, but because there are no single circles that means this picture is only a mixture of compounds.

Example Question #43 : Compounds

4

Each circle represents an atom and each different color represents a different kind of atom. If two atoms are touching then they are bonded together as a compound.

Mixture of Elements

Correct answer:

Element

Explanation:

This picture only contains pictures separate circles. All the circles are the same color. Therefore this is a picture of just one element.

Mixture of Compounds and Elements

Element

Mixture of Compounds

Compound

Correct answer:

Mixture of Compounds

Explanation:

There are two different types of molecules in this picture (one with two circles, and another with three circles). Therefore this picture is a mixture of compounds.

Example Question #48 : Compounds

8

Possible Answers:

Compound

Mixture of Compounds

Mixture of Compounds and Elements

Mixture of Elements

Element

Correct answer:

Compound

Explanation:

Although it can hard to to tell, this picture just contains several of the same type of molecules. Therefore this picture is just one compound.
