Balancing an equation is to make sure the numbers of the same atoms are the same on both side of the equation Displacement Reactions and Ionic Equations When we place a metal in solution of a less reactive metal,themore reactivemetal will displacethe less reactivemetal from the solution. This...
Tips: If you could not find kChem when tap globe key : Remove kChem in the system settings, re-add it. --- Easter Egg This is not a keyboard , it's a tool which could help you to create a chemical equation image.
balanced equation- chemical equation in which the number and type of atoms and the electric charges are the same on both the reactant and product sides of the equation. Balmer series- the part of the hydrogen emission spectrum for electron transitions n=2 and n>2, There are four lines in...

If possible, always review the topics you learn in class, and review your notes on the same day. ●Secondly, think carefully whether you really understand the meaning of a formula (分子式) or the use of an equation (方程式). A good way to test your understanding is to explain a ...
The very word chemicals has come to be used all too frequently in a pejorative sense. There is, as a result, a danger that the pursuit and application of chemical knowledge may be seen as bearing risks that outweigh the benefits. It is easy to underestimate the central role of chemistry ...

Joe Townsend, and Jim Downing from the Unilever Centre for Molecular Science Informatics at the University of Cambridge, the Chem4Word project took inspiration from the mathematic-equation authoring capabilities in Word 2007. We also have taken advantage of user-interface extensibility and XML fe...
In the 1980s NMR became well known to the general public, when the technique was applied to medicine—though the name of the application was altered to magnetic resonance imaging (MRI) to avoid the loaded word nuclear. Many other instrumental methods have seen vigorous development, such as ...
