(18 cards)
Refinery Gases
1/6
Used as a fuel for cooking, heating
Gasoline
2/6
Used as fuel for cars and other internal combustion engines.
Kerosene
3/6
Primarily used as jet fuel and as a fuel for heating and lamps.
Diesel
4/6
Used as fuel for diesel engines in vehicles, machinery, and power plants.
Heavy Fuel Oil
5/6
Used as fuel for large ships, power plants, and industrial heating
Bitumen
6/6
Used in road construction as asphalt for paving roads and roofing.
name the 6 main fractions obtained from crude oil
- Refinery Gases (LPG)
- Gasoline
- Kerosene
- Diesel
- Heavy Fuel Oil
- Bitumen
PH scale
- Acid = 0-6
- Neutral = 7
- Alkaline = 8-14
examples of an acid
- lemon juice
- vinegar
examples of an PH neutral
pure water
examples of an alkaline
- bleach
- baking soda
describe the trend in boiling point, flammability and viscosity of the main fractions.
boiling point = more higher boiling point as you go down
flammability = less flammable as you go down
(Bitumen being not flammable)
viscosity = increase down
viscosity definition
It describes how thick or thin a fluid is
- high viscosity fluids flow slowly (like honey)
- low viscosity fluids flow easily (like water).
define a hydrocarbon
a compound made from hydrogen and carbon ONLY.
describe crude oil
Crude oil is a dark, thick liquid found underground, composed mainly of hydrocarbons. It is used as a primary source of energy and raw material for fuels and chemicals.
a mixture of different length hydrocarbons.
what’s the general formula for an alkane.
CₙH₂ₙ₊₂
where n is the number of carbon atoms.
define molecular and empirical formula.
Molecular formula: Shows the exact number of atoms of each element in a molecule (e.g., C₂H₆ for ethane).
Empirical formula: Shows the simplest whole-number ratio of atoms in a compound (e.g., CH₃ for ethane).
