Bromine

== Description ==
A corrosive, nonmetallic element. Bromine is a dark, reddish-brown liquid at room temperature. It occurs in seawater at concentrations of about 65 parts per million. Bromine was first identified as a separate chemical element in a 1826 publication by a French chemist Antoint-Jerome Balard. Bromine is used in fumigants, dyes, photographic chemicals, and as a flame retardant in plastics. It is also used for the chemical extraction of gold from ores.

Bronze

== Description ==
An alloy of copper and tin sometimes containing small amounts of zinc, lead, silver, aluminum, or phosphorus. Bronze artifacts have been discovered in Thailand dating from 3600 BCE, while Chinese and Middle Eastern bronzes have been dated as early as 2000 BCE. Bronze is stronger, harder, and more durable than brass or iron. It was used for weapons, tools, vases, household goods, coinage, jewelry, and cast sculptures. US standard bronze is composed of 90% copper, 7% tin and 3% zinc. Ancient bronze alloys sometimes contained up to 14% tin. Bronzes are usually a yellowish gold in color unless the copper concentrations are greater than 95% then they tend to be reddish. Bronzes with high tin concentrations (20-25%) are hard, brittle, and steel-colored. 
See also art bronze, and gold bronze.

Bronze disease

== Description ==
A destructive corrosion process that occurs on copper and bronze objects. Bronze disease occurs from the reaction of chlorides on copper in the presence of moisture and oxygen. It produces blue-green powdery spots usually containing atacamite (copper oxychloride). Once initiated, the reaction is cyclic making it difficult to halt, unless the reacting compounds (chloride, water, oxygen) are eliminated.

Brown banded cockroach

== Description ==
A small, light brown cockroach, Supella longipalpa and Supella supellectilium, that grows up to 12.5 mm long. The adult brown banded cockroach has light yellow cross bands on the dorsal side. Both the nymphs and adults feed on almost anything, such as starchy, sugary and proteinaceous foods. They will eat cloth that is sized with starch or glue. The adult insects can live almost 2 years and lay eggs that cemented together in a sausage-shaped case that hatch into nymphs in about 70 days. The egg case is usually attached to walls, cabinets, ceilings or any region where the temperature is warmer. The brown banded cockroach travels on cabinets and walls and is rarely seen on the floor. Cockroaches are nocturnal and are sensitive to light. Common desiccating powders such as borax, Dri-die and sulfur are used along with pesticides to exterminate cockroaches.
