Question

I need a question paper of class 10 mid term in which these two question are available 1.What is amfoteric oxide? 2.What is nutralisation reaction?

Answer 1

In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid as well as a base. Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide.

In chemistry, neutralization or neutralisation, is a chemical reaction in which an acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.

PLEASE MARK ME AS A BRAINLIST ANSWER

Answer 2

acid with base react and neutralise to form salt and water
