Question

Non metals do not generally do not react with acids.name two non metals that react only with hot concentrated acids

Answer 1

Answer:

Metals, like gold and platinum, do not react with dilute acids. Non-metals generally do not react with acids. Some non-metals, like sulphur and phosphorus, react with hot concentrated sulphuric acid, or nitric acid, but they do not liberate hydrogen gas.

Answer 2

Non-metals do not generally react with acids because when a substance, reacts with acids it provides electrons to the H+ ions produced by the acids. Non-metals are acceptors of electrons and hence, they cannot donate electrons. They have 4,5,6,7 electrons in their valence shell and therefore, they readily gain electrons.
