How many mole of O2 are needed for complete combustion of two mole of butane C4H10?
ANS 13
2C4H10+13O2>>8CO2 + 10H2O
so what does this tell you? Why did you post this question?
Thnx bobpursley
To determine the number of moles of O2 needed for the complete combustion of two moles of butane (C4H10), we need to balance the chemical equation for the combustion of butane.
The balanced equation is as follows:
C4H10 + 13/2 O2 → 4 CO2 + 5 H2O
From the balanced equation, we can see that 1 mole of butane reacts with 13/2 moles of O2. Therefore, if we have 2 moles of butane, we would need:
2 moles C4H10 × (13/2 moles O2 / 1 mole C4H10) = 13 moles O2
So, 13 moles of O2 are needed for the complete combustion of two moles of butane (C4H10).
