Question

What is the chemical formula of a compound that is composed of ions ca2+ and br-

Answer 1

The chemical formula of a compound that is composed of ions Ca+2 and Br-1, is Ca(Br)2.

Answer 2

Answer: Calcium Bromide

Step-by-step explanation:

• The valency of Calcium (Ca) is +2 and valency of Bromine (Br) is -1.

• When these two chemically combine with each other, Calcium Bromide (
  `CaBr_2`) is formed.
• In order to form a neutral molecule,
  `2 Br^-` combines with one
  `Ca^(2+)`.
• So, the resulting chemical formula would be
  `CaBr_2`.
