Question

elements, compounds, and mixtures
classify each of the pictures below by placing the correct label in the blanks below:
a - element
b - compound
c - mixture of elements
d - mixture of compounds
e - mixture of elements and compounds
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.

Explanation:

Step1: Recall definitions

An element has only one - type of atom, a compound has different types of atoms bonded together, a mixture of elements has different non - bonded elements, a mixture of compounds has different compounds, and a mixture of elements and compounds has both non - bonded elements and compounds.

Step2: Analyze picture 1

All particles are the same type of compound (two different atoms bonded), so it is a compound (B).

Step3: Analyze picture 2

There are two types of non - bonded atoms, so it is a mixture of elements (C).

Step4: Analyze picture 3

There are compounds and non - bonded elements, so it is a mixture of elements and compounds (E).

Step5: Analyze picture 4

There are two types of compounds, so it is a mixture of compounds (D).

Step6: Analyze picture 5

All particles are the same element (single atoms of the same type), so it is an element (A).

Step7: Analyze picture 6

All particles are the same compound, so it is a compound (B).

Step8: Analyze picture 7

All particles are the same element (diatomic molecules of the same type), so it is an element (A).

Step9: Analyze picture 8

There are non - bonded atoms and compounds, so it is a mixture of elements and compounds (E).

Step10: Analyze picture 9

There are non - bonded atoms and compounds, so it is a mixture of elements and compounds (E).

Step11: Analyze picture 10

There are two types of compounds and non - bonded elements, so it is a mixture of elements and compounds (E).

Step12: Analyze picture 11

All particles are the same compound, so it is a compound (B).

Step13: Analyze picture 12

All particles are the same compound, so it is a compound (B).

Step14: Analyze picture 13

All particles are the same compound, so it is a compound (B).

Step15: Analyze picture 14

There are two types of compounds, so it is a mixture of compounds (D).

Step16: Analyze picture 15

There are two types of compounds and non - bonded elements, so it is a mixture of elements and compounds (E).
