CE : Section 5 Fossil Fuels 1. 93 1(c) Alkenes can be obtained from petroleum fractions by a process called ’cracking’. Using a suitable petroleum fraction‚ a student carried out this process in the laboratory and collected the gaseous product over water. (i) What is ’cracking’ ? (ii) Draw a labelled diagram of a laboratory set-up that can be used for carrying out the process and collecting the gaseous product. (iii) An important safety precaution in the experiment is to prevent sucking

Cleaner Renewable Resources‚ VS. Fossil Fuels By Michael Lawson Assignment: To Drill or Not to Drill Renewable energy is a debatable issue because on one hand‚ it could potentially reduce the need to Burn fossil fuels. Burning fossil fuels for energy releases much of the harmful gases that exist today. Scientists estimate that about 35 percent of the greenhouse gases‚ such as carbon dioxide‚ being released into the atmosphere are from the United States (Renewable Energy Is Beneficial

beginning of industry humans have been in search of fuel to power machines and generate energy. Fossil fuels‚ such as crude oil and coal‚ discovered beneath the Earth’s surface were found to be an excellent source of fuel. These fossil fuels are burnt in order to generate the energy required to complete various tasks. However‚ we are now realizing the problems that are created by using fossil fuels to generate energy. These problems are so great that they will force humans to find an alternative

diminishing fossil fuels In 1977‚ the President of the United States of America‚ Jimmy Carter‚ advocated for the use of alternative energy to the American people “because we are now running out of gas and oil‚ we must prepare quickly to strict conservation [of fossil fuels] and to the use of coal and permanent renewable energy sources‚ like solar power.” More than thirty years later his announcement still rings true and is relevant. In fact‚ the current situation of non-renewable fuels is worse than

Oil‚ or petroleum‚ is one of the most common fossil fuels utilized by people all over the world on a daily basis. Crude oil is a smelly‚ yellow-black‚ viscous liquid composed of mostly nitrogen‚ oxygen‚ and sulfur‚ which is

Scientific and Economic Advantages and Disadvantages of Unconventional Fossil Fuels December 13‚ 2013 EES 402: Energy Issues in Geoscience Term Paper I. Introduction “Just as fossil fuels from conventional sources are finite and are becoming depleted‚ those from difficult sources will also run out. If we put all our energy and resources into continued fossil fuel extraction‚ we will have lost an opportunity to have invested in renewable energy.” –David Suzuki (Brainy Quote)

1/ what is the essential difference between alternative energies (AE) and fossil fuels? Alternative energies will not have a lot of pollution‚ but fossil fuels will cause some pollution of the environment. Some fossil fuels causes environmental pollution‚ for example‚ global climate change‚ a lot of carbon dioxide cause the greenhouse effect‚ acid rain emissions of harmful gases cause serious pollution to the atmosphere. 2/ name the AE that you have chosen to research.

These poisons have led to long-term detrimental effects on ecosystems and has attributed to the premature deaths of 40% or 2.8 billion of the world’s

“The use of fossil fuels‚ such as coal and oil‚ belongs to the past.” For the time being‚ the world is mostly dependent on the use of fossil fuels. All the infrastructure is fossil fuel based. i.e. if the world runs out of fossil fuels now‚ there won’t be any alternative energy source to power the entire world. Fossil fuels are usually found in rock formations containing fossils from decomposed animals and plants. The formation of fossil fuels happens in the course of hundreds of millions of years

Fossils Fossils are the remains of ancient organisms‚ usually animals and plants but there are also minute bacteria and occasionally fungi. They are preserved by natural processes of burial. Most are entombed in sediment i.e. mud‚ silt or sand which with time transforms into a sedimentary rock such as sandstone. Rarely‚ fossils are enclosed in ash erupted from volcanoes‚ resin that oozes from trees and hardens into amber‚ or natural tar seeping from the ground. Normally only the resistant hard
