Question
Identify the products (X and Y) obtained in the reactions below.
Mercury (II) oxide 
X + Y
- X = Mercury, Y = water
- X = oxygen, Y = mercurium oxide
- X = Mercury, Y = mercury (I) oxide
- X = Mercury, Y = oxygen
Hint:
A chemical reaction is in which the bonds are broken within reactant molecules, and new bonds are formed within product molecules to form a new substance.
The correct answer is: X = Mercury, Y = oxygen
the products (X and Y) are obtained in the reactions below
Mercury (II) oxide Mercury + oxygen.

John performed one experiment. Find out the composition of air. He took the test tube fitted with a rubber cork. Then he poured some fresh lime water into it. Then he fitted the two long-bent tube through the two holes of rubber cork. He blew the air by an air pump through the long tube. The lime water present inside turns into a milky solution. This shows that the air contains
