Question

DEFINE:
1) metallurgy
2) amphoteric oxide

Answer 1

metallurgy--
the process of extracting metals from their ores is called metallurgy.
,#amphoteric oxides--
the oxides which shows dual nature of acids as well as base,
ex is cu( copper)

Answer 2

Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are called alloys.

An amphoteric oxide is an oxide that can act as either an acid or base in a reaction to produce a salt and water. Amphoterism depends on the oxidation states available to a chemical species. Because metals have multiple oxidation states, they form amphoteric oxides and hydroxides.
