The chemical formula for pure water is H 2 O. Pure water breaks up into an equal number of H + (aq) and OH - (aq) ions. As the amounts of the H + and OH - ions are equal, water i
Characteristics of tautomerism (a) Tautomerism (cationotropy) is caused by the oscillation of hydrogen atom between two polyvalent atoms present in the molecule. The modificati
While studying evolution, a student comes across a cladogram that includes clades like amphibia, reptilia, aves, and mammalia. What must be the basal clade?
It is important to differentiate the stoichiometric or empirical formula of a molecular substance from its molecular formula. The former expresses only the relative numbers of atom
