New discoveries in chemistry include a special coating for roof tiles that reduces air pollution, the ability to provide information regarding the dangers of sewer gases and improvements in food storage options. New discoveries continue to improve human life and protect the environment.Know More
Chemists have recently developed a special titanium dioxide coating for roof tiles which breaks down nitrogen oxide and reduces air pollution. The amount of nitrogen oxides broken down annually is equal to the amount an automobile produces driving 11,000 miles. According to ScienceDaily, the cost of titanium dioxide to treat an average home is about $5.
Another advancement in chemistry involves chemical analysis of sewer gas to determine the condition of sewer pipes. As pipelines begin to deteriorate, the gases emitted contain more sulfur dioxide and are more uniform in nature. This knowledge can warn maintenance teams as to when they should look for developing problems to be able prevent contamination of surface and ground water.
Chemistry also continues to improve food storage alternatives. ScienceDaily reports that use of essential oils from oregano and cloves in plastic wrap helps to retard the growth of mold and bacteria in bread. When bread that contains the commonly used calcium propionate is stored in normal plastic bags, the preservative loses its effectiveness after 10 days. However, bread stored in edible films made with these essential oils continues to remain fresh for a much greater period.Learn more about Chemistry
In chemistry, pK is the logarithmic value of the dissociation constant, Ka, of a hydrogen atom present on a molecule. A molecule has a distinct pK for each hydrogen atom that can be deprotonated. The acidity of a specific hydrogen atom in a molecule is represented by the pK value.Full Answer >
Chemistry performed in the liquid phase is defined as wet chemistry. The term "wet chemistry" is synonymous with "bench chemistry" because the experiments are often performed at a chemistry bench. Wet chemistry involves the use of beakers, flasks and other glassware to perform general experiments.Full Answer >
Chemistry provides several key advantages to the public and the fields of medicine by allowing for basic needs to be met and allowing for the production of medicines. Chemistry, indirectly and directly, provides benefits for people around the world on a daily basis. It helps meet basic needs such as clothing, energy and shelter, and contributes to the improvement of air, water and soil quality.Full Answer >
AP or "advanced placement" chemistry is a hard high school course often taken by college-bound students looking to improve their chances for admission into a four-year college or university. This course, along with other challenging, advanced-placement courses, is recommended to high school students who plan on attending college after graduation.Full Answer >
