Following within the culture of the 1st 5 variants, the aim of this industry prime textbook, "Chemistry in Context, 5th Edition", is to set up chemical rules on a need-to-know foundation inside of a contextual framework of important social, political, financial and moral concerns. The non conventional procedure of "Chemistry in Context" mirror modern technological concerns and the chemistry rules imbedded inside them. international warming, trade fuels, foodstuff, and genetic engineering are examples of concerns which are coated in "CIC".

Example text

Together with particulate matter (PM), they represent the most serious air pollutants at the Earth’s surface. Let’s now examine the health effects of each. Carbon monoxide earned a nickname as “the silent killer” because you cannot detect it with your senses. Once in the lungs, carbon monoxide enters the bloodstream and disrupts the delivery of oxygen throughout the body. In an extreme case, such as breathing auto exhaust or furnace emissions in a confined space, carbon monoxide can be fatal. 4) and should be used outdoors or vented if used indoors.

Common names cannot be figured out. If you don’t already know them, then you simply have to memorize them. Fortunately, the list is short, and we will introduce each name as needed. In the next two sections, we will explore combustion reactions. Following our needto-know philosophy, for combustion you will need to know the names of several common hydrocarbons, that is, compounds of hydrogen and carbon. Methane (CH4) is the simplest hydrocarbon. Other small hydrocarbons include ethane, propane, and butane.

Our noses also warn us to avoid certain places. But some of the more dangerous air pollutants have no odor. As a result, it may be necessary to rely on specialized scientific equipment to monitor the presence of such substances in the air. It is rather surprising that the gases that cause serious air pollution are present in relatively small amounts, generally in the range of parts per million to parts per billion. Yet even at such low concentrations, they can do significant harm. In this chapter, we focus on four gases that contribute to air pollution at the surface of the Earth.
