Bitesize crude oil and fuels
Crude oil, coal and gas are fossil fuels. They were formed over millions of years, from the remains of dead organisms: coal was formed from dead trees and other plant material. crude oil and gas were formed from dead marine organisms. Ethanol is an alcohol-based fuel made by fermenting and distilling starch crops, such as corn. It can also be made from "cellulosic biomass" such as trees and grasses. The use of ethanol can reduce our dependence upon foreign oil and reduce greenhouse gas emissions.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. -H is made by reactibg steam with either coal or natural gas, not a carbon neutral fuel. -v flamable, can explode (potentially more dangerous than oil based fuels) -needs to be chilled and compressed in strong tanks, hard to transport. -H (used as rocket fuel), extremly light, very powerful. Most of the compounds found in crude oil are hydrocarbons. They are so-called because they only contain hydrogen and carbon atoms, which are joined together by covalent chemical bonds. There are different families of hydrocarbon, each containing a variety of related chemicals. Crude oil is a mixture of a very large number of compounds. It is formed from the remains of plants and animals which died millions of years ago. This is why it is called a fossil fuel. Most of the compounds in crude oil consist of molecules made up of hydrogen and carbon atoms only, we call these type of compounds hydrocarbons. GCSE Chemistry module: Crude Oil and Fuels By the end of this topic you will have covered: - Crude oil - Fractional distillation of oil - Burning fuels - Alternative fuels - Cracking hydrocarbons - Polymers GCSE revision videos and apps from L
Crude oil Carbon atoms can form four covalent bonds, and join together to form chains and rings in hydrocarbon molecules . In the ball and stick models below, carbon atoms are black and hydrogen
23 Sep 2019 Fossil fuels take millions of years to form; therefore petroleum is considered a Petroleum refining is the process of converting crude oil into useful Example of catalytic equation (BBC Bitesize – accessed December 2018) :. Chemistry - Vegetable Oils and Their Uses (AQA). In GCSE Science students will look at crude oil and other fuels but they will also look at plant oils. This quiz is 15 Oct 2018 In the United States it has significantly boosted domestic oil sources of energy, and encouraging continued reliance on fossil fuels. Crude oil was formed from the remains of tiny sea animals and plants and is therefore a fossil fuel. Small marine animals and plants that died millions of years BBC Bitesize for Chemistry papers · BBC Bitesize for Physics papers C8: Rates and equilibrium; C9: Crude oil and fuels; C12: Chemical analysis; C13: The Medicinal paraffin (Liquid paraffin) NOT the fuel, about 2 cm3 The demand for petrol is greater than the gasoline fraction obtained by distilling crude oil.
Crude oil is a finite resource. Petrol and other fuels are produced from it using fractional distillation and cracking. Combustion products may cause environmental and health problems.
Crude oil, coal and gas are fossil fuels.

The use of ethanol can reduce our dependence upon foreign oil and reduce greenhouse gas emissions.
Crude oil, liquid petroleum that is found accumulated in various porous rock formations in Earth's crust and is extracted for burning as fuel or for processing into
The oil is called crude oil (or petroleum, from Latin - rock oil), and has natural gas in it or in a pocket above it trapped by non-porous rock. Drilling through the rock allows the oil and gas to escape to the surface. Crude oil is a mixture of hydrocarbons and is used to make fuels, polymers, chemicals, solvents, lubricants and roads.
C1.4 Crude Oil and Fuels . Quick revise. Rate: Fossil fuels developed billions of years ago, when dead organic matter became buried at the bottom of the sea and altered as a result of anaerobic digestion. Oil deposits in the North Sea are around 150 million years old, while much of Britain’s coal began to form over 300 million years ago. Crude oil contains a mixture of different hydrocarbon compounds that boil at different temperatures. The larger the hydrocarbon molecule (the longer its carbon-chain length), the higher its boiling point. Liquids boil (liquid→gas) at their boiling point and start to condense (gas→liquid)
