Chemical Weapons Chemical weapons use the toxic properties of chemical substances rather than their explosive properties to produce physical or physiological effects on an enemy. Although instances of what might be styled as chemical weapons date to antiquity‚ much of the lore of chemical weapons as viewed today has its origins in World War I. During that conflict "gas" (actually an aerosol or vapor) was used effectively on numerous occasions by both sides to alter the outcome of battles. A significant

Liquid Crystal Displays (LCD) – Working We always use devices made up of Liquid Crystal Displays (LCDs) like computers‚ digital watches and also DVD and CD players. They have become very common and have taken a giant leap in the screen industry by clearly replacing the use of Cathode Ray Tubes (CRT). CRT draws more power than LCD and are also bigger and heavier. All of us have seen an LCD‚ but no one knows the exact working of it. Let us take a look at the working of an LCD. We get the definition

this experiment was to obtain some experimental measurement of Vapor Liquid Equilibrium for the Ethanol – Water system to verify the literature data. For this the Ethanol – Water system was heated to a certain temperature which is called the equilibrium temperature at atmospheric pressure and equilibrium temperature and compositions of vapor and liquid were measured. At the equilibrium temperature the samples of both vapor and liquid were taken in two different test-tube and the refractive index of

The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to decompose into two gases‚ due to the absence of anything solid or liquid following the reaction. A wood
