What is the History of chlorine?
150930
Chlorine (Gr. χλωρος, greenish yellow) was discovered in 1774 by Swedish chemist Carl Wilhelm Scheele, who mistakenly thought it contained oxygen. Chlorine was given its name in 1810 by Sir Humphry Davy, who insisted that it was in fact an element.\n\nChlorine gas was first used as a weapon against human beings in WWI on April 22nd, 1915.

keep your pool clean.i don't know if chlorine is good for your pool.\n\nthere is a website below that i hope helps.

A chlorine atom needs only one electron to have a stable outer shell.\n\nLooking at its atomic number, a chlorine atom has the same number of electrons.

It might be worth thinking about entropy.  \n\nIf you take a system that has Chlorine molecules together and Oil molecules then the system is more chaotic with Chlorine and Oil randomly mixed so the driving force is increased chaos (although you have a gas going to a gas dissolved in a liquid the chaos of the total system may increase)\n\nHowever on a molecular level, it does seem confusing, to work out the arrangement. it would be important to look at the magnitude of the VDW forces between Oil-Oil chains and their usual form, and the net benefit of the VDW forces between Oil and CL and the added entropic element.

First, look at the oxygen.  Oxygen has a charge of 2-, and there are 4, so in the entire molecule, oxygen gives a charge of 8-. The total charge of the molecule is 1-, therefore to find Cl, create the equation -8+x = -1\nx=7\nTherefore chlorine has a charge of 7+\nThe total charge of the molecule = the sum of the charges of each atom

Hmm, kinda hard to help you here, since we can't see all your options for the first two.  The ellipses (. . .) indicate that you have more in your message than is being displayed.  Perhaps if you retyped them, it would be easier for us to help.\n\nHere's what I *can* help with:\n\nHalogens:Reactive as Noble Gas:STABLE\n(the halogens are very reactive gases, while the noble gases are extremely stable, almost to the point of being inert)\n\nOxygen:molecule as chloride:ION\nOxygen gas is a molecule, while chloride is the ionic form of chlorine\n\nRatio:subscript as oxidation number:CHARGE\nthe ratio of components in a mixture is denoted by the subscripts, as the oxidation number of an atom is denoted by its ionic charge

More than likely a chlorine gas I would rec. NOT experimenting with the two. I work in the water treatment field. Trust me

NaCl IS NOT TWO ATOMS (sodium and chlorine) BONDED TOGETHER!\n\nNaCl is what is known in chemistry as an ionic salt.  That means that a very positively charged Na+ ion met up with a very negatively charged Cl- ion, and because opposite charges attract, they got close to each other in what is known as an ionic bond, which isn't really a bond, just two particles hanging out together.

This is different for the different halogens. Chlorine is obtained by electrolysis of sea-water, but bromine and iodine can be obtained by using the differences in reactivity between them and chlorine.  Look them up as "extraction of chlorine" and "extraction of bromine" (and so on) and you'll get the answers.

single covalent bond.the electron arrangement of chlorine is 2.8.7\nthe outermost shell lack of one electron to achieve stable electron arrangement.since covalent  bonding involves sharing of electrons,one pairvof electros os shared between two chorine atoms to produce a chlorine molecule.\n\ngood luck!\n\nthe answers are definetily correct .i coppied from chemistry text book from malaysia.

i am not sure but every pools i've visited use chlorine and people say it kills bacteria

Chlorine (Cl2) is dosed in water to disinfect gems & bacteria, so it might have an effect.Pressure pump does increase this corrosion due to the friction between the water & the pipe.

One of the earliest attempts to explain the nature of water was made by the Greek philosopher Aristotle in 335 B.C. when he issued his Theory of Matter. According to Aristotle's theory, every substance was a combination of four basic elements—fire, earth, air and water. This idea was to keep alchemists busy for centuries trying to change common metals into gold by rearranging their "elements." They were not very successful, however, since no one was ever able to break down a substance and find out just how much fire, earth, air and water was in it. Not until the eighteenth century did scientists decide that air, earth and fire were not really elements at all, and in 1781 a British chemist proved that water wasn't an element either.\n\nThat year Joseph Priestley exploded a mixture of air and hydrogen in a bottle as "a mere random experiment to entertain a few philosophical friends," and noted with interest that the explosion caused moisture to condense inside the bottle. He repeated the experiment until he was certain that the moisture was produced from the reaction of air and hydrogen, thereby proving that water, rather than being a basic element, was itself composed of other chemicals.\n\nIn 1783 the French chemist Antoine Lavoisier elaborated on Priestley's experiment and discovered that the hydrogen was not combining with air to form water, but only with the oxygen in air. Further experiments determined that a molecule of water contained two atoms of hydrogen and one atom of oxygen, a chemical combination which has been given the symbol H2O.\n\nThe discovery that water was H2O or "hydrogen oxide" raised more questions than it answered, for chemists learned that despite its apparent simplicity water is actually a most puzzling and paradoxical substance which seems to defy the rules of chemistry.\n\nCompared to other liquids, water requires a great deal of heat to raise its temperature even a few degrees, and once it is warm it loses its heat slowly. This ability to "store" heat enables water to modify the world's climate. Oceans don't warm up as fast as the coastlines they touch, nor do the)' cool off as fast, with the result that coastal areas usually have milder winters and cooler summers than areas inland. For example, Bismarck, North Dakota has average temperatures of 8 degrees in January and 70 degrees in July, while Seattle, at the same latitude, has averages of 41 degrees and 66 degrees for the same two months.\n\nWater is the only substance found abundantly in all three natural forms—liquid, solid and gas. But in changing from one form to another some more peculiarities become evident. One of water's most paradoxical qualities is that when it changes into a solid it expands (and so becomes relatively lighter for its volume). Other substances, with the exception of bismuth, contract or condense and so become relatively heavier. Of course, if water condensed when it froze the world would have some serious problems. Ice would form on the bottom of a lake because it would be denser and therefore heavier than the liquid water. And there it would stay, growing upwards, killing all marine life. Underneath the surface, shielded from much of the sun's heat, very little of it would melt in the spring and eventually the rivers, lakes and seas in cooler parts of the world would become solid ice.\n\nThe world would have different but even greater temperature problems if there were no water vapor in the air to absorb the sun's heat during the day and retain it during the night. Daylight hours would be miserably hot, and nightfall would bring freezing temperatures. In southern states where winter crops are grown, farmers dread a cold, dry, clear night for this same reason. Without clouds and moist air to act as insulation, the earth's heat quickly escapes, permitting the temperature to drop unusually low and sometimes ruin citrus fruit and tender pl

Mixing chlorine and alcohol to produce an exposion is quite dangerous, and has caused numerous injuries in children who tried to emulate those videos.  However, the reason for the explosion is that chlorine is highly reactive because it only needs to acquire one electron to fill its valence shell, so it reacts explosively with alcohol to form alkyl chloride, also called chloroalkane.

The CRC Handbook of Chemistry and Physics has all kinds of good information like that (although it is pricey).\n\nOr, search the web for the specific liquid of interest.
