Business Requirements. Business requirements for a project are a series of needs that must be fulfilled to achieve a high-level objective. Clear business requirements help ensure that the end result of a project fulfills the stakeholders' needs. Functional Requirements.
Introduction. The solubility of aromatic hydrocarbons, such as toluene, in water, and the decrease in solubility in aqueous salt solutions is an important factor controlling the behavior of hydrocarbons in a variety of environments.. Variation of toluene solubility (expressed as C 0 / C salt, where C 0 =toluene solubility in distilled water, and C salt =toluene solubility in salt solution) versus salt concentration for various inorganic salts.
Fatty ingredients such as butter help interfere with crystallizationagain, by getting in the way of the sucrose molecules that are trying to lock togeter into crystals. Toffee owes its smooth texture and easy breakability to an absence of sugar crystals, thanks to a large amount of butter in the mix.
