An addition reaction is a situation in which two substances called reagents react with each other to form a product. While the...
In 1789, Antoine Lavoisier wrote "Elementary Treatise on Chemistry," which is considered the first modern book on chemistry. He defined an element as a simple substance that can't be broken down further and listed many of the elements that we know of today. He arranged the elements into met...
‘The notion of an element is central to chemistry and serves a number of purposes,’ Ghibaudi says. ‘For example, it identifies what stays unchanged in a system undergoing a chemical transformation, and it distinguishes between chemical and nuclear changes. So it seems reasonable to expect ch...

Chemistry in Everyday Life We use chemistry every day, even if we don’t realize it. When you bake cookies, chemistry changes the ingredients in the oven. Soap cleans your hands because of chemistry. Even brushing your teeth is a chemical reaction. Chemistry helps with cooking, cleaning, and...
Chemistry is the branch which deals with the detailed study of matter, its properties, how and why atoms/substanced combine or separate to form other substances. Understand all the basic concepts of Organic, Inorganic, and Physical Chemistry with detaile
Alloys- mixtures in which the main element (or, usually, elements) are metal(s). A more technical definition of an alloy is 'a partial or complete solid solution of one or more elements in a metallic matrix'. Common examples of alloys include bronze, brass and steels. When alloys are sp...

enclosed container, the container will weigh exactly as much as it did prior to the reaction, only it will have changed to ash. Because of his efforts in popularizing chemistry and making it more accessible to the common person, Lavoisier is often regarded as the father of modern chemistry. ...
QSY is a non-fluorescent quencher, however the QSY probes don’t have a MGB moiety. If for example, you are running a 4-plex reaction, two TaqMan assays can be FAM and VIC probes labeled with an MGB-NFQ quencher while the other two assays should have ABY ...
