Explanation:

Reaction of metal and non-metals with oxygen

Metals react with oxygen to form metal oxides.These metal oxides are basic in nature.

Metal + Oxygen —>MetaI Oxide

1)When magnesium burns in air,it combines with the oxygen of air to form magnesium oxide(basic oxide)

Magnesium +oxygen > Magnesium

Oxide

2 Mg(s) + 02 (g) > 2MgO(s)

Magnesium oxide dissolves in water to form magnesium hydroxide solution.

MgO + 1--120

Magnesium hydroxide turns red litmus to blue which shows that magnesium oxide is a basic oxide.

Answer 2

Answer:

Reaction between metal and oxygen

When a metal reacts with oxygen, a metal oxide forms. The general equation for this reaction is: metal + oxygen → metal oxide.

EXAMPLE

• magnesium + oxygen → magnesium oxide
• iron + oxygen → iron oxide
• copper + oxygen → copper oxide.

Reaction between non metal and oxygen

Non-metals react with oxygen to form non-metal oxides. The non-metal and oxygen gas (O2) are the reactants in this type of reaction, and a non-metal oxide is the product.

EXAMPLE

• The reactions of carbon and sulfur with oxygen are examples of non-metals reacting with oxygen.
• Similarly when Carbon react with with one molecule of Oxygen i.e. C+O = CO (carbon monoxide) which is a neutral oxide.
