andy chuks A clathrate, clathrate compound or cage compound is a chemical substance consisting of a lattice of one type of molecule trapping and containing a second type of molecule. The name clathrate complex used to refer only to the inclusion complex of hydroquinone, but recently it has been adopted for many other weak composites which consist of a host molecule...

andy chuks The equation above shows the mole ratios of the reaction. 4 moles of ammonia (NH3) reacting with 3 moles of Oxygen (O2) produced 2 moles of Nitrogen (N2) and 6 moles of water (H2O).
Note 1 mole of gas is = 22.4dm3
Therefore 4 moles of NH3 = 89.6 dm3
Since it was complete combustion, that means if 15dm3 of NH3 was burnt completely 0.67 moles of... Read All 1024 April 2012
andy chuks The Kinetic Theory of Matter states that matter is composed of a large number of small particles (atoms or molecules) that are in constant motion.
The small particles are always in constant motion and collide with one another and their container.
The degree of motion or collision of these particles is dependent of the state of the matter or the force... Read All 0002 January 2012
andy chuks A Polarimeter is a device for studying a transparent sample between crossed polarizing devices.
A polarimeter is a scientific instrument used to measure the angle of rotation caused by passing polarized light through an optically active substance.
Some chemical substances are optically active, and polarized (ie unidirectional) light will rotate either... Read All 0028 November 2011

andy chuksHow to Name Hydrocarbons - Locate the longest continuous chain of carbon atoms. Remember that the longest chain may be bent.
- Number your chain from the end nearest a double or triple bond, otherwise from the end with the closest branch.
- Use Greek numerical prefixes to find the "parent name" of your compound. This is based on the size of your longest chain. For... Read All12 April 2011Comment
