Give the names of the elements present in the following compounds:(a) Quicklime (b) Hydrogen bromide

Sure! Let's identify the elements present in the given compounds.

Quicklime

• Chemical Formula: $\text{CaO}$
• Elements Present:
  1. Calcium (Ca)
  2. Oxygen (O)

Quicklime, or calcium oxide, is derived from limestone and is primarily used in various industrial processes, including metallurgy and construction. It consists of calcium, which is a metal, and oxygen, a non-metal.

Hydrogen Bromide

• Chemical Formula: $\text{HBr}$
• Elements Present:
  1. Hydrogen (H)
  2. Bromine (Br)

Hydrogen bromide is a diatomic molecule made up of hydrogen and bromine. It's a colorless gas with a pungent smell and is highly soluble in water, forming a strong acid known as hydrobromic acid.

In summary, the elements present in the compounds are:

• Quicklime: Calcium and Oxygen
• Hydrogen Bromide: Hydrogen and Bromine
