For the combustion of ethane,beginning with 0.27 mole of CH3 CH3.
How many moles of CO2 are obtained when the CH3 CH3 is completely combusted?
The balanced chemical equation for the combustion of ethane is:
2C2H6 + 7O2 → 4CO2 + 6H2O
This means that for every 2 moles of ethane (CH3CH3) that react, 4 moles of CO2 are produced.
To determine how many moles of CO2 are produced when 0.27 moles of ethane is combusted, we can use a proportion:
2 moles of CH3CH3 : 4 moles of CO2
0.27 moles of CH3CH3 : x moles of CO2
Cross-multiplying and solving for x, we get:
x = (0.27 moles of CH3CH3 x 4 moles of CO2) / 2 moles of CH3CH3
x = 0.54 moles of CO2
Therefore, when 0.27 moles of ethane is completely combusted, 0.54 moles of CO2 are produced.
