Several commercial, residential and industrial products contain red phosphorous, including chemical mixtures, plastics, flame retardants, striker plates, incendiary shells, smoke bombs and tracer bullets. Red phosphorous is contained in fireworks and sparklers and sometimes in trace amounts in matches and candles. It is considered a volatile and reactive substance and is only added to products in controlled environments.Know More
Red phosphorous is relatively toxic and flammable and is produced by heating white phosphorous to high temperatures. Red phosphorous is more stable than white phosphorous and is considered to be nontoxic in its pure form, which makes it more suitable than white phosphorous for adding to a larger variety of manufactured products.
Safety matches, or matchsticks, are common household items containing red phosphorous. This element is added to the striking panel on matchboxes, and a small amount is added to match tips too. It is then combined with a binding substance, such as polyvinyl alcohol and a sulfide filler, before being applied using a special printing method.
Red phosphorous is also used as a flame retardant in plastic products, such as polyamides, epoxy resins, rubbers and polyurethanes. Polyamides generally take the form of plastic spray cans and applicators. They are used to hold abrasive cleaners, adhesives, fabric coating and more.Learn More
The products of a reaction between HNO3 and BA(OH)2 are H2O and Ba(No3)2. The balanced equation for the reaction is notated as 2 HNO3 + Ba(OH)2 ? Ba(NO3)2 + 2 H2O.Full Answer >
In a chemical reaction, the reactants are the elements present when the reaction begins, and the products are the elements and compounds produced as a result of the reaction. In a chemical formula, the reactants are on the left side of the arrow, and the products are on the right.Full Answer >
According to the State University of New York, human-computer interaction is important because it is fundamental to making products more successful, safe, useful, functional and, in the long run, more pleasurable for the user. HCI is the study of how people interact with computers and to what extent computers are developed for successful interaction with human beings.Full Answer >
Coefficients are the numbers placed before the reactants in a chemical equation so that the number of atoms in the products on the right side of the equation are equal to the number of atoms in the reactants on the left side. If a written chemical reaction were not balanced in this manner, there would be no information available regarding the relationship between the reactants and products. Also known as stoichiometric coefficients, these numerical values demonstrate that the number of atoms on either side of the equation are equal to each other.Full Answer >
