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 (CH3CH3) is:
2CH3CH3 + 7O2 → 4CO2 + 6H2O
This means that for every two moles of ethane, we get four moles of CO2.
To find out how many moles of CO2 are obtained from 0.27 moles of ethane, we can use a proportion:
2 moles ethane : 4 moles CO2 = 0.27 moles ethane : x moles CO2
Cross-multiplying and solving for x, we get:
x = (4 moles CO2 / 2 moles ethane) x 0.27 moles ethane
x = 0.54 moles CO2
Therefore, when 0.27 moles of ethane is completely combusted, we get 0.54 moles of CO2.
