Alkanes as Fuels

Question 1

Describe Complete combustion of alkanes?

Answer 1

this is where alkanes burn in oxygen completely -> CO2 + H2O.

Question 2

Whats the impact of size of alkane on complete combustion?

Answer 2

The larger the chain, the more energy produced

Question 3

Describe Incomplete combustion of alkanes

Answer 3

this is where alkenes burn in limited oxygen supply -> CO (or C-soot) + H2O

Question 4

Whats the effect of CO on humans?

Answer 4

CO binds to haemongoblin stronger than oxygen displaying it and preventing O2 from bonding. Its very poisonous

Question 5

Whats the effect of soot

Answer 5

Soot can cause breathing difficulties

Question 6

How and what is the effects of Acid Rain

Answer 6

is produced from burning fossil fuels, releasing SO2 and NOx, causing this which damages plants and kills fish.

Question 7

Write the 4 step equations for production of Sulfuric acid

Answer 7

S + O2-> SO2 and 2SO + O2 -> 2SO3

SO2 +H2O -> H2SO3 and SO3 + H2O -> H2SO4

Question 8

How the 3 Step equations for production of Nitric acid from N2 and O2 being heated in atmosphere

Answer 8

N2+ O2 -> 2NO

2NO + O2 -> 2NO2

2NO2+H2O-> HNO2 +HNO3

Question 9

How do catalytic converters work in cars

Answer 9

reduce the amount of unburned hydrocarbons and NOx being released into the atmosphere. Catalysts like platinim are spread over thin honeycomb mesh increasing surface area
