Answer:
Explanation:
1. The molecular formula for water is H2O. One molecule of water consists of one oxygen atom covalently bonded to two hydrogen atoms
2.The chemical formula of ammonia is NH3, and its molar mass is 17.03 g/mol. The ammonia molecule has a trigonal pyramidal shape, with nitrogen connected to the three hydrogen atoms. The nitrogen atom has a lone electron pair, which makes ammonia a base.

4.the chemical structure of chlorine gas is Cl2 and its molecular weight is 70 g/mol. Its structure is Cl-Cl, which is also called the element form of the chlorine element, consist in 2 atoms of chlorine joined by a covalent bond.
5.Ethane is a colorless, odorless, and flammable gas with a chemical formula of C2H6; it has two carbon (C) atoms and six hydrogen (H) atoms. It's only composed of carbon and hydrogen atoms, so it is classified as a hydrocarbon.
