Chlorine

I: Chemical Formula and Breakdown Chlorine gases chemical formula is CI2. The elements that make chlorine gas is mainly chlorine. Chlorine is a common element and is used in salt, which is very important. Chlorine is highly reactive. Also, a highly toxic greenish yellow gas, has a pungent odour, and fumes in moist air. Its density is .003, so it is very light. II: Physiological/Psychological Effects Because of its reactivity, Chlorine does not exist in the free elemental state in nature, although

Chlorine      Chlorine is (at room temperature) a greenish-yellow gas that can be readily liquefied at 5170 Tarr or 6.8 atmospheres, at 20 C (68 F), and has a very disagreeable odor. It’s Element Symbol is Cl, atomic number is 17, and atomic mass is 35.453. Chlorine’s melting point is -101 C or 149.8 F. The boiling point is -34.05 C or -29.29 F, at one atmosphere pressure. Chlorine is a member of the halogen group. Chlorine was discovered by Swedish scientist Karl Wilhelm

Element: Chlorine General Information We researched the chemical element known as chlorine. Chlorine has an atomic number of 17 and an atomic weight of 35.453. It has a valence number of 3. The element has 3 energy levels. Chlorine exists as a greenish-yellow gas at normal temperatures and pressures. Chlorine is second in reactivity only to fluorine among the halogen elements. Chlorine is a nonmetal. It is estimated that 0.045% of the earth's crust and 1.9% of sea water are chlorine. Chlorine

I have chosen to research for my assignment is Chlorine. It is a very important element as Chlorine is in a lot of things that most people use in their everyday lives. Chlorine is an element of the periodic table. It’s chemical symbol is Cl, it has the atomic number of 17 and an approximate atomic mass of 35.5. It was discovered by a man named Carl Wilhelm Sceele who mistakenly thought it was a gas that contained oxygen and discovered chlorine and noticed its other properties and uses.

RESULT Chlorine: Sample no. 1 N1V1 of water sample = N2V2 of hypo solution N1×50 = N/50×V2 N1 = V2/2500 N Where V2 = 7.8 = 7.8/2500 N1 = .00312 Strength of chlorine = N1×35

Chlorine, element No. 17 on the Periodic Table of Elements, has multiple applications, atomic number 17 , atomic symbol is Cl , atomic weight is 35.453 . It is used to sterilize drinking water and to disinfect swimming pools, and it is used in the manufacturing of a number of commonly used products, such as paper, textiles, medicines, paints and plastic, particularly PVC. Moreover, chlorine is used in the development and manufacturing of materials used in products that make vehicles lighter, from

Chlorine (Cl) is an element and it has an atomic number of 17. It forms diatomic molecules (Cl₂). It belongs to the halogens family and it reacts with almost all the other elements except with the noble gases. It has an atomic mass of 35.453u and the most abundant isotope of this element is chlorine-35. There two stable isotopes of chlorine which are chlorine-35 and chlorine-37. Chlorine is in a gas state at room temperature. It boils at -34.04°C and melts at -101.5°C. It has a density of 3.2 g/L

the swimming pools use chlorine to sanitize. Chlorine can cause dry and irritated skin, as well as damaged hair. It could even cause some sicknesses. A swimmer´s life is not so easy! Is there a way to successfully remove chlorine in a swimmer's hair by making a more efficient swim spray for hair? How is chlorine used and what is it? Chlorine is used in swimming pools to kill harmful bacteria. It is a chemical used to disinfect water(Department of Health, n.d.,para 2). Chlorine is a yellow-green gas

Chlorine Chlorine has 17 protons, 18 neutrons, and 17 electrons. It's atomic number is 17 and the atomic mass is 35.45. Its symbol on the periodic table is Cl. Question #1 It is surprising how many ways humans use chlorine. One way humans use chlorine is to kill bacteria and germs in pools. It cleanses the pool so when people go swimming, they will not get sick. Chlorine is also used to make paper. Scientists use it to drain all the color to make it white. Chlorine is also used
