write the chemical formulae of the following
Answers
Explanation:
Magnesium chloride (MgCl2)
An inorganic compound consisting of one magnesium and two chloride ions. Magnesium chloride is used to treat or prevent magnesium deficiency (lack of natural magnesium in the body).
(b) Calcium oxide (CaO)
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound.
(c) Copper nitrate Cu (NO3)2
Cupric Nitrate is a bluish-green, odourless crystalline (sand-like) material.
(d) Aluminium chloride (AlCl3)
Aluminium chloride (AlCl3) is the main compound of aluminium and chlorine. It is used to treat excessive sweating, also called hyperhidrosis.
(e) Calcium carbonate (CaCO3)
Calcium carbonate also is used as an antacid to relieve heartburn, acid indigestion, and upset stomach.
