    Question

    What is the correct formula for the compound calcium carbide?

    1. CaC
    2. Ca2C
    3. CaC2
    4. Ca2C4

    Hint:

    A compound always tends to be neutral.

    The correct answer is: CaC2

      • In the chemical formula, metals are written first followed by non-metals.
      • The subscript tells about the number of atoms present in each.
      • A compound always tends to be neutral.
      • Calcium has an oxidation state of +2, and carbon has an oxidation state of -1. To make the compound neutral one calcium atom and two carbon atoms are required. Hence, the correct formula for calcium carbide is CaC2.
