Question 9

Petroleum:

Answer 9

Naturally occuring liquid found in formation in the earth consisting of a complex mixture of hydro carbons

Question 10

Synthetic Ethanol

Answer 10

Ethanol produced from the hydrolysis of ethylene which is a petro chemical

Question 11

Advantages

Answer 11

Theoretically inexhaustible fuel source
When direct combustion of plant mass is not used to generate energy (i.e. fermentation, pyrolysis, etc. are used instead), there is minimal environmental impact
Alcohols and other fuels produced by biomass are efficient, viable, and relatively clean-burning
Available throughout the world

Question 12

Disadvantages

Answer 12

ould contribute a great deal to global warming and particulate pollution if directly burned
Still an expensive source, both in terms of producing the biomass and converting it to alcohols
On a small scale there is most likely a net loss of energy–energy must be put in to grow the plant mass
