The various principle pollutants emit from vehicles are as follows- Carbon monoxide (CO) Suspended particulate matter (SPM) Oxides of nitrogen (NOx) Hydrocarbons (HC) Polynuclear aromatic hydrocarbons (PAHs) 2005 Air Toxic Emissions from On-road Mobile Sources (Tox-weighted) Affects of Automobile Pollution 1.

here in the Philippines as kalburo. When this chemical compound is mixed with water there will be a chemical reaction and it produces acetylene gas. The two anions of carbon‚ the carbide (C4-) and dicarbide (C22-) ions react with water to produce hydrocarbons. The carbide ion gives methane gas‚ and the dicarbide ion gives acetylene gas. This video shows the reaction between calcium carbide and water to produce acetylene and calcium hydroxide. Acetylene is combustible‚ and burns when ignited. Acetylene

chlorine (a chlorofluorocarbon‚ or CFC). CFCs are nontoxic‚ nonflammable‚ and make almost ideal aerosol propellants. But when it was learned that they causedestruction of stratospheric ozone‚ they were replaced with other solvents‚ like alcohols and hydrocarbons. Unfortunately‚ these are flammable. One of the polymers used is polyvinylpyrrolidine‚ which is also used to glue the layers of wood in plywood together. An non-water soluble polymer called polydimethylsiloxane is added to make the hold last a

Making Connections: Chemistry Assignment By. Sujay Sukumar 5. a) When analyzing the graph‚ a relationship between the hydrocarbon chain of the alkane and its corresponding boiling point can certainly be noticed. There is a increasing correlation which can be explained using the theory that as each hydrocarbon chain gets bigger‚ there are more atoms and thus more electrons which contributes to higher dispersion forces and therefore a higher boiling point which is clearly seen through the graph.

Carbon tax is an environmental tax levied on the carbon content of fuels. It is a form of carbon pricing. Carbon is present in every hydrocarbon fuel ‚ such as coal‚ petroleum‚ and natural gas. It is then released as carbon dioxide (CO2) when they are burnt. In contrast‚ non-combustion energy sources—wind‚sunlight‚ hydropower‚ and nuclear—do not convert hydrocarbons to CO2. CO2 is a heat-trapping "greenhouse" gas. Scientists have debated and discussed the potential effects on the climate system of

Precautionary measures to be taken when cleaning cargo tanks: Gas-Freeing for Cargo Tank entry Cargo Tank entry shall not be permitted unless the Oxygen Content is 21% and the hydrocarbon vapor content is less than 1% of the Lower Flammable Level (LFL).

disturbance and thermal decomposition. All transformers generate gasses to some extent at normal operating temperature. Insulating mineral oils for transformer are mixtures of many different hydrocarbons and the decomposition process for these hydrocarbons are complex. During this process‚ active hydrogen atoms and hydrocarbons fragments are formed. These fragments can combine with each other to form gasses such as Hydrogen (H2)‚ Methane (CH4)‚ Acetylene (C2H2)‚ Ethylene (C2H4)‚ Ethane (C2H6) and many more

Natural gas can often times be confused with gasoline; however‚ it is a colorless‚ odorless‚ and smokeless gas. 1. It is composed of hydrocarbon compounds‚ (carbon dioxide‚ hydrogen‚ water vapor‚ and 90% methane.). a. It is generated when the formation of plant and animal matter get trapped under solid rock‚ below loads and tons of pressure for millions of years underneath the earth’s
