q.3. fill in the blanks using the following word bank. compound homogeneous heterogeneous element q.4. which of the diagrams below represent a compound made of two elements? a) b) c) d)

Answer

Explanation:

Step1: Recall compound definition

A compound is a pure - substance made up of two or more different types of elements chemically combined in a fixed ratio.

Step2: Analyze each diagram

  • Diagram a: Shows individual atoms of the same type, so it is an element.
  • Diagram b: Shows molecules made up of two different types of atoms chemically bonded, which is a compound made of two elements.
  • Diagram c: Shows molecules of the same type, but they are made up of only one type of atom, so it is an element.
  • Diagram d: Shows a mixture of different types of atoms and molecules, not a pure compound.

Answer:
