investigated is chlorine‚ which was named by Sir Humphry Davy in 1810 for the Greek word chloros- meaning greenish yellow. The element was first synthesized in 1774 when the Swedish chemist Carl Wilhelm Scheele combined the mineral pyrolusite with the solution hydrochloric acid. Originally‚ Scheele believed that this newly produced gas contained the element oxygen. However‚ in 1810 Sir Humphry Davy proved that this gas was actually its own distinct element. The chemical symbol for Chlorine is Cl; the

and their uses Exploration milestone-an overview. INTRODUCTION: By definition petroleum is a generic name for hydrocarbons‚ including crude oil‚ natural gas liquids‚ natural gas and their products. Petroleum comes from the Latin petra meaning rock or stone & oleum meaning oil. Petroleum occurs in the earth in combination of any of the four states: gas‚ liquid‚ semisolid‚ and solid. Chemically‚ petroleum is a mixture of carbon‚ hydrogen and oxygen (called hydrocarbons) with minor amounts of nitrogen

next 5 minutes. How do manufacturers bleach something into light colors? How do things in white are easily to get yellow? Why do they do so? The reason of getting yellow. The solution to the problem. Difference between sulfide bleach and chlorine bleach. PPT 3 We heard words such as “bleach for unbleachables” from TV commercials. But what exactly is bleaching? Does it mean making things turn into a lighter color or does it mean making thing become purely white? According to Wikipedia

Review the behavior of the gas phase vs. the liquid phase. Solution: a) The volume of the liquid remains constant‚ but the volume of the gas increases to the volume of the larger container. b) The volume of the container holding the gas sample increases when heated‚ but the volume of the container holding the liquid sample remains essentially constant when heated. c) The volume of the liquid remains essentially constant‚ but the volume of the gas is reduced. The particles in a gas are further apart than

How does chlorine effect the evaporation of pool water? Over time‚ sunlight and evaporation cause the chlorine and other chemicals in pool water to lose their effectiveness. Chemicals that are designed to disinfect swimming pools have chlorine concentrations ranging from approximately 12 to 95%. The concentration must be high because the chemicals are designed to be diluted in water. The amount of chlorine you need to add to a swimming pool is greater than the amount you need to add to regular drinking

GAS LAWS Properties of Gases Gases expand into any available volume • gas molecules escape from open containers. Gases are completely miscible • once mixed they will not spontaneously separate. Gases are described in terms of T‚ P‚ V and n Volume‚ Amount and Temperature • A gas expands uniformly to fill the container in which it is placed – The volume of the container is the volume of the gas – Volume may be in liters‚ mL‚ or cm3 • The temperature of a gas must be indicated
