What is the Difference between Flammable and Combustible Liquids? Put simply‚ flammable and combustible liquids are liquids that can burn. The real difference lies within their flash point range‚ or lowest temperature at which vapours of the material will ignite when supplied with an ignition source. Flammable and combustible liquids are utilised in most workplaces‚ from manufacturing to retail and service entities. To ensure the safety of property‚ people‚ and the environment‚ both flammable

Functional Groups of Organic Compounds A functional group is a specific arrangement of atoms in the HC derivative other than carbon and hydrogen. Literally‚ the functional group determines the functions of the particular HC derivative in chemical reactions. This means that the specific properties of the HC derivative are due to its functional group. Each functional group is attached to an alkyl radical (R). An alkyl radical is one H atom less than the given alkane. The alkyl radical (R) uses

Chem 3418 Organic Chemistry Laboratory I Acid Base Review Definition In general‚ an acid is a substance that can donate a proton (H+) and a base is a substance that can accept a proton. Any proton in an organic molecule can potentially be donated. The most acidic proton in a molecule would be donated first. Any lone pair in an organic molecule can act as the proton acceptor. An acid (HA) reacts with a base (in this case H2O) to form the conjugate base of the acid (A-) and the conjugate acid of the

“Science does not know it’s debt to imagination.” “Men love to wonder‚ and that is the seed of science.” Ralph Waldo Emerson was right on point when he said these two statements. There have been numerous great scientists that have come in and out of this world‚ and there are many to still come. When Emerson said these two quotes‚ he was talking about all of these scientists. The world we live in today would not be the same without the imagination and wonder of scientists; therefore we owe everything
