Question

Write down the reaction of metals and non metals with oxygen

Answer 1

metals:

Metals react with oxygen to form metal oxides. These metal oxides are basic in nature. Magnesium oxide dissolves in water to form magnesium hydroxide solution

non metals:

Non-metals react with oxygen in the air to produce non-metal oxides. Non-metal oxides such as sulphur dioxide and nitrogen oxide are responsible for acid rain.

Answer 2

1). metal +oxygen = Metal oxide

     Ca +O —CaO

CaO+ H2O—Ca(OH)2

metal oxide is basic in natur e

2). non metal +oxygen—non metal oxide

S +3/2 O2— SO3

SO3 + H2O—-H2SO4

non metal oxides are acidic in nature
