Chemistry is a broad scientific field, and its relevance is seen in almost every aspect of society, including medicine, cooking, environmental processes, cleaning and manufacturing goods. Class notes from the Department of Chemistry at Michigan State University state that the Chemical Age is one of the great three ages of the 20th century, the others being the Nuclear Age and the Electronic Age.Know More
The Chemical Age began around 1930, and its effects reach deeply into daily life. Humans rely heavily on a wide array of chemical tools; adhesives, cleaning agents, synthetic fabrics, pesticides, vitamins, plastics and explosives are just a few. In a world without chemistry, explains Science Week, humans would never have invented liquid oxygen, a key component in rocket fuel. The space race would not have happened and the related technologies society gained from it, such as the Internet and satellite TV, would not exist. Humans would still be plagued by illnesses, like smallpox and polio, and penicillin would not be available to fight bacterial infections.
The Chemical Age had negative consequences as well. Pollution, environmental disturbance and effects on human health are problems that manifest as society comes to rely more and more on chemical tools. Careful handling of chemical products and a thorough testing of their effects is an essential step in reaping the benefits of chemistry.Learn More
The chemical reaction between aluminum and bromine is an exothermic one that produces aluminum bromide. The equation of the chemical reaction is 2 Al + 3 Br2 ? 2 AlBr3. It indicates that two molecules of aluminum combine with three molecules of bromine to produce two molecules of aluminum bromide.Full Answer >
As the name suggests, metalloids often possess properties that true metals hold. In addition to these, metalloids also have non-metal properties. They are able to conduct electricity and heat, like metals, but not as well.Full Answer >
The molar mass of butane, which is represented by the chemical formula C4H10, is 58.12 grams per mole. The molar mass of butane is calculated by adding the atomic weight of each carbon and hydrogen atom contained in the compound.Full Answer >
CFCs, also known as chlorofluorocarbons, are compounds that are most commonly used as refrigerants, propellants and solvents. Best known as "Freon," CFCs have been discontinued as the main source of coolant in air conditioners and refrigerators because of their ability to deplete the ozone layer in the atmosphere.Full Answer >
