background Air pollution consists of many types. Smog‚ acid rain‚ ozone layer‚ and the green house effect destruction all cause serious problems for people and the environment. Smog and acid rain are caused by the release of noxious gases‚ like carbon monoxide. The ozone layer is being destroyed by another form of air pollution‚ Chlorofluorocarbons‚ even though these were band in 1995 people now use hydro chlorofluorocarbons‚ which destroy the ozone more slowly (maybe take this out?).

POLLUTION Pollution is the introduction of contaminants into the natural environment that cause adverse change.[1] Pollution can take the form of chemical substances orenergy‚ such as noise‚ heat or light. Pollutants‚ the components of pollution‚ can be either foreign substances/energies or naturally occurring contaminants. Pollutant A pollutant is a substance or energy introduced into the environment that has undesired effects‚ or adversely affects the usefulness of a resource. A pollutant

Internal combustion engines using gasoline emit carbon monoxide‚ lead and particulates into the atmosphere. Pictures of air pollution What cause air pollution- * Burning of garbage’s * Using gasoline emit carbon monoxides * sulphur dioxide and nitrous oxide * sugarcane factories at time emit black polluted dust * cement and chemical plants emit white polluted dust‚ tainting

produce carbon dioxide and water during combustion test. When the oxygen is limited‚ the product will be carbon monoxide and water. The alkenes are highly flammable and burn readily in air‚ forming carbon dioxide and water. In this experiment‚ the combustion of cyclohexene burns in an orange flame and produces relatively high amount of black soot. The black soot produced is actually carbon monoxide. Cyclohexane is a saturated hydrocarbon and cyclohexene is an unsaturated hydrocarbon due to the presence

Chemical bond From Wikipedia‚ the free encyclopedia A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electrostatic force of attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such ascovalent or ionic bonds and "weak bonds" such as dipole–dipole interactions

We‚ as an industrial society‚ have become far too familiar with terms like smog‚ radon‚ lead‚ asbestos‚ ozone‚ and carbon monoxide. We have also seen on the news‚ read in the newspaper‚ or experienced in our own lives some of the harmful consequences that result from these pollutants -- perhaps as allergies or congestion from exposure to smog or more dangerous carbon monoxide poisoning. Regulations have been established in an attempt to minimize these harmful air pollutants. For example‚ we have

Alternative Fuels – Data By: Denise Claire Tan Yet Nee Structure and physical properties of Molecules Nowadays‚ there are a lot of alternative fuels which have discovered by human beings in order to replace the depleting non-renewable fossil fuels supply. In fact‚ organic chemistry has successfully proved that organic compounds can be served substitution of fossil fuel supply. The structure and physical properties of organic molecules are characteristics that aid them to become useful fuels

*CHEMICAL KINETICS Collision theory and rates of reaction *One of the main considerations when examining chemical reaction is whether it will take place fast enough for it to be useful. *In other words‚ there’s no point carrying out a reaction if it takes 150 years to form the product! *Many chemical reactions occur very quickly. *Studying Reaction Rates *Defined as the change in concentration of reactants of products per unit time. *Units: mol dm¯³ s¯¹ *Rate of Reaction * ‚ the

Worldwide‚ there are about six million deaths each year from illnesses that are traced back to tobacco use. Also‚ for every person that dies‚ at least thirty people live with serious smoke-related health complications (Smoking and Tobacco Use‚ CDC 2015). There are many factors that shape smoking to be unhealthy‚ but why are people still choosing to do it…especially the youth? Does the youth know/understand these factors that make smoking so unhealthy? It is good that people are trying to form

contain an anion of oxygen in the oxidation state of −2. Most of the Earth’s crustconsists of solid oxides‚ the result of elements being oxidized by the oxygen in air or in water. Hydrocarbon combustion affords the two principal carbon oxides:carbon monoxide and carbon dioxide. Even materials considered pure elements often develop an oxide coating. For example‚ aluminium foil develops a thin skin of Al2O3 (called a passivation layer) that protects the foil from further corrosion.[2]Different oxides of
