Question

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

• 1) All the molecules are the same and composed of two different atoms (bonded), so it is a compound (\(B\)).
• 2) There are two different types of un - bonded atoms, so it is a mixture of elements (\(C\)).
• 3) There are two different types of molecules (one is a diatomic element and the other is a compound), so it is a mixture of elements and compounds (\(E\)).
• 4) There are two different types of molecules (one is a diatomic element and the other is a compound), so it is a mixture of elements and compounds (\(E\)).
• 5) All the particles are the same un - bonded atoms, so it is an element (\(A\)).
• 6) All the molecules are the same and composed of three different atoms (bonded), so it is a compound (\(B\)).
• 7) All the molecules are the same and composed of two of the same atoms (bonded), so it is an element (\(A\)).

Answer:

1. \(B\)
2. \(C\)
3. \(E\)
4. \(E\)
5. \(A\)
6. \(B\)
7. \(A\)
