Question

What volume of oxygen is required to produce 100 centimeter cube of sulphur dioxide

Answer 1

The reaction that takes place is as follows:

S + O2--------> SO2

100 cm3 of SO2 are needed.

From the reaction, it is observed that 1 volume of O2 forms 1 volume of SO2.

So, let 1 volume = 100 cm3 ( As 100 cm3 of SO2 is to be formed).

Hence, 1 volume of O2 gas will have to react completely with sulphur to form 1 part SO2 gas.

So, 100 cm3 of O2 will react completely with sulphur to give 100 cm3 of sulphur dioxide gas.

So, 100 cm3 of Oxygen is required.
