Question

What is the volume of oxygen required for the complete combustion of 4 litre of ethane?

Answer 1

Answer:

1 litre of ethane requires = 3.5 litres of oxygen for combustion.

4 litres of ethane will require = 3.5×4=14 litres of oxygen.

Hence, 4 litres of ethane requires 14 litres of oxygen for combustion.

Answer 2

Answer:

14 liters of oxygen are required for the complete combustion of 4 liters of ethane.

Explanation:

Ethane:- ethane stands for $C_{2}H_{6}$ basically it is an organic compound it is a colorless substance at standard temperature and pressure and also odorless gas, it belongs to the hydrocarbons family it is also used as a petrochemical by-product of petroleum refining.

Combustion:- it is a chemical reaction basically it releases heat and light when this reaction takes place in the form of flame. It is an exothermic redox reaction that mostly occurred between a fuel and an oxidant and lastly produces smoke.

combustion reaction as follow:-

$C_{2}H_{6} + O_{2} \to CO_{2} + H_{2}O \\C_{2}H_{6} +\frac{7}{2} O_{2} \to 2CO_{2} + 3H_{2}O$

   $4$ liters of ethane at S.T.F $=\frac{4}{22.4}$ moles $= 0.1785$ moles

   $1$ moles of $C_{2}H_{6}$ $= \frac{7}{2}$ moles of $O_{2}$

   $0.1785$ moles of $C_{2}H_{6}$  $= \frac{7}{2}$ ×$0.1785$ moles of $O_{2}$ $= 0.62475$ moles of $O_{2}$

   the volume of $O_{2}$ $=0.62475$ × $22.4$ liters $= 13.9944$ liters $=14$ liters of $O_{2}$.

So, $14$ liters of oxygen are required for the complete combustion of $4$ liters of ethane.
