the chemical composition corresponds to the relative amounts of the elements constituting the substance. Normally, it can be expressed with achemical formula. For an example, the chemical formula for water is H2O, thus the chemical composition of water may be interpreted as a 2:1 ratio...
Write the respective valency for each element and criss-cross. 2. If the valency is equal then just write out the formula. 3. If a number is required for polyatomic ions then a bracket must be used. 4. Reduce the ratio by a common factor if possible. ...

silicon carbide, exceedingly hard, synthetically produced crystallinecompoundofsiliconandcarbon. Itschemical formulais SiC. Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More recently, it has found application in refractory ...
The most important part for nearly all of us was, that within 3 minutes we were able to draw molecules the way we wanted them to be drawn! Also as I already told you, we tested a few things and nothing came close to ChemDoodle, as it exceeds ChemDraws capabilities in a lot of ...
The first element in the formula is given first, using the element’s full name. The second element is named as if it were an anion. Prefixes are used to denote the numbers of atoms present. If the first element exists as a single atom, the prefixmono-is omitted. For example, CO is...
