1
Q
What is bio fuel?

= fuel made from plants
2
Q
What does carbon neutral mean?
A
= actiivy that does not have any no net annual carbon (green house gas) emission to the atmosphere
3
Q
Why is fermentation seen as carbon neutral?
A
= co2 given off would be extratced from the air by photosynthesis where the plant grew
= no net co2 emission into the atmopshere
4
Q
What is the equation for removal of co2 by photosynthesis?
A
= 6CO2 + 6H2O ==> C6H12O6 + 6O2
5
Q
What is the equation that releases co2?
A
= C6H12O6 ==> 2CH3CH2OH + 2CO2
2CH3CH2OH + 6O2 ==> 4CO2 + 6H2O
