Can Fracking Solve the Global Energy Crisis? Hydraulic fracturing or better known as fracking is a very contentious and cost-saving procedure in which fossil fuels are extracted from the earths crust. Instead of conventional oil drilling‚ it is used to exploit any possible sources of oil and natural gas‚ beyond the major known well sites. It was introduced in the 1940s and since then the practice has become increasingly controversial regarding its environmental impact. The pros and cons of this

in earth’s atmosphere. Helium is the by-product of millennia of radioactive decay from the elements thorium and uranium. The helium is mostly trapped in subterranean natural gas bunkers and commercially extracted through a method known as fractional distillation. C) The loss of helium on Earth would affect society greatly. Defying the perception of it as a novelty substance for parties and gimmicks‚ the element actually has many vital applications in society. Probably the most well known commercial

Another term ‘LNG’ (liquified natural gas) is also in news these days. This is also a fuel and is obtained by liquifaction of natural gas. Petrol‚ diesel and kerosene oil are obtained by the fractional distillation of petroleum found under the earth’s crust. Coal gas is obtained by the destructive distillation of coal. Natural gas is found in upper strata during drilling of oil wells. The gas after compression is known as compressed natural gas. LPG is used as a domestic fuel with the least pollution

Chemical Report The chemical I will be writing this report on is oxygen. The name oxygen comes from the Greek word “oxygens‚” which means “acid producer”. Dictionary.com defines oxygen as “a colorless‚ odorless‚ gaseous element constituting about one-fifth of the volume of the atmosphere and present in a combined state in nature.” Oxygen has many uses today. First‚ oxygen is used by people‚ plants‚ and animals in the respiration process. Tanks of oxygen are used in the healthcare field to treat

Developing Fuels * All gases take up the same volume under the same conditions. AT room temperature and room pressure this volume is 24 dm3. * Number of moles= volume in dm3 24 * Balanced equations can also be used to work out gas volumes. In the equations: 2Na + 2H2O 2NaOH + H2‚ where 15g of sodium is reacted‚ you can work out the volume of gas from working out the number of moles in 15g Na = 0.65 mol. Then you see that 2 mol of Na 1mol of H2‚ Thus 0.65 mol Na 0.325 mol H2. 0.325

(3x25 mL). The acidic compound was then washed with 100 mL of water‚ dried over MgSO4‚ filtered. The solvent CH2Cl2 then was removed by evaporating it. Purification of The Unknowns The liquid yield (acidic component) was purified by fractional distillation. The boiling point of the compound was determined afterwards. The solid yield (neutral component) was purified by recrystallization by using ethanol as the solvent. ~20 mL of ethanol was added to the solid. Water was then added to this

Chemistry design: Fuel energy lab Research question: What is the energy density of cyclohexane‚ and how does it compare to the energy density of normal hexane? Variables: Independent variable – The independent variable in this experiment will be the type of fuel that will be used. This will be either Hexane or Cyclohexane. Each type will be given to us and labelled so it will be quite simple to control this variable. This cannot be measured using any apparatus so the lab assistant must be entrusted

Chemistry All about matter There are three different stages of matter: Solid‚ Liquid and Gas Solid (s): Have a certain volume and shape. “Particles” are arranged in a specific crystalline patter and they only vibrate around fixed positions. Liquid (l): Have a fixed volume‚ but not shape. The particles have some freedom and can move around each other. They collide often. Gas (g): Doesn’t have a fix volume or shape. (Takes up the space where it is) Particles move freely in all space available
