Tris(pentafluorophenyl)borane, sometimes referred to as "BCF", is the chemical compound (C 6 F 5) 3 B.It is a white, volatile solid. The molecule consists of three pentafluorophenyl groups attached in a "paddle-wheel" manner to a central boron atom; the BC 3 core is planar.
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
Constructive developmental framework. The constructive developmental framework (CDF) is a theoretical framework for epistemological and psychological assessment of adults. The framework is based on empirical developmental research showing that an individual's perception of reality is an actively constructed "world of their own", unique to them ...
Fillet of iridescent shark. A fish fillet, from the French word filet (pronounced [filÉ›]) meaning a thread or strip, [1] is the flesh of a fish which has been cut or sliced away from the bone by cutting lengthwise along one side of the fish parallel to the backbone. In preparation for filleting, any scales on the fish should be removed.
Fugacity and BCF relate to each other in the following equation: = [6] where Z Fish is equal to the Fugacity capacity of a chemical in the fish, P Fish is equal to the density of the fish (mass/length 3), BCF is the partition coefficient between the fish and the water (length 3 /mass) and H is equal to the Henry's law constant (Length 2 /Time 2) [6]
Baldwin's rules in organic chemistry are a series of guidelines outlining the relative favorabilities of ring closure reactions in alicyclic compounds. They were first proposed by Jack Baldwin in 1976. [1][2] Baldwin's rules discuss the relative rates of ring closures of these various types. These terms are not meant to describe the absolute ...
A fillet knife (also called a filleting knife) is a kitchen knife used for filleting. It gives good control and aids in filleting. It is a very flexible member of the boning knife family that is used to filet and prepare fish. Fillet knife blades are typically 15 to 28 cm (6 to 11 in) long. This allows them to move easily along the backbone and ...
Year Yet questions. If you want help or explanations as you go along, turn to the chapter in PART TWO that relates to the question you're working on. 2. Read Part One and Part Two as preparation for your workshop, perhaps making notes as you read. When you've finished, set aside three hours and write your answers to the questions in Part Three.
