Concept explainers
(a)
Interpretation:
The formula of a compound formed with hydrogen and sulfur needs to be determined.
Concept introduction:
All the elements in the periodic table can be classified as metals, non-metals and metalloids. Metals are electropositive elements which mainly form basic oxides and non-metals are electronegative elements, they mainly form acidic oxides. Non-metals are placed at the right side of the periodic table and their oxides react with water to form acidic solutions. Hydrogen is a unique element which can react with metal as well as non-metals. It forms hydride with metals and different acidic compounds with non-metals.
(b)
Interpretation:
The formula of a compound formed with hydrogen and nitrogen needs to be determined. The compound so formed must be liquid at 1 atm and
