Answer 1

Answer:

Diagram B is a mixture of compounds

Explanation:

The false statement about any of the diagram is that diagram B is a mixture of compounds.

Diagram is not a mixture of compounds. It is a single compound in gaseous state .

• A compound is a combination of elements in a definite grouping.
• The properties of the compound is distinct from that of the element that combines to form it.
• Therefore, since we just a black and yellow circle, the diagram is a compound and nothing more.
• The other descriptions are perfect.
