ACD/ChemSketch is freeware available for personal, home, and educational use from ACDlabs.It has comprehensive chemical drawing features and can directly connect to PubChem, eMolecules and Chemspider to search these large databases by structure or substructure.
The school executives launched a web portal to help the students get lecture notes, worksheets, and other necessary academic materials. It is also possible to see the examination marks and the report cards of the students. The system is managed by the system's admin, Mr. Imran. The web portal was published along with a new website in 2016. [2]
The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.
Here is the current progress of locating pictures for the remaining elements without images, and what users can possibly do to help the search. Feel free to add your own findings (remember to sign), or discuss them on this page's talk page. See here for more details.
In chemistry, the valence (US spelling) or valency (British spelling) of an atom is a measure of its combining capacity with other atoms when it forms chemical compounds or molecules. Valence is generally understood to be the number of chemical bonds that each atom of a given chemical element typically forms.
The names "caffeine" and "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound.The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" simply names it.
A chemical composition specifies the identity, arrangement, and ratio of the chemical elements making up a compound by way of chemical and atomic bonds.. Chemical formulas can be used to describe the relative amounts of elements present in a compound.
