contains sufficient energy to break the weaker nonpolar chlorine-chlorine bond‚ but it has insufficient energy to break the stronger carbon-hydrogen bond. The fracture of the chlorine molecule leads to the formation of two highly reactive chlorine free radicals (chlorine atoms). A free radical is an atom or group that has a single unshared electron. This initial reaction is called the initiation step of the mechanism. Once the high-energy chlorine free radicals are formed‚ the energy source (UV light

Most common gases used in the war were phosgene‚ chlorine‚ and mustard gas. Chlorine is often used in biology the first being in emergent properties. Pure chlorine is a poisonous gas; used in emergent properties of a compound‚ when chemically combined with sodium it forms sodium chlorine also known as table salt. Out of the several elements in the human body‚ one of them being chlorine makes up 0.2% of our body mass. Lastly‚ we see Chlorine in electron transfer and ionic bonding: “When an atom

Electrolysis Electrolysis is the process by which ionic substances are broken down into simpler substances using electricity. During electrolysis‚ metals and gases may form at the electrodes. What is electrolysis? Ionic substances contain charged particles called ions. For example‚ lead bromide contains positively charged lead ions and negatively charged bromide ions. Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric

with ozone.4 They are broken down into chlorine atoms by ultraviolet radiation.5 Chlorine acts as the catalyst for breaking down atomic oxygen and molecular ozone into two molecules of molecular oxygen. The basic set of reactions that involve this process are: Cl + O3 -->ClO + O2 and ClO + O -->Cl + O2 The net result: O3 + O -->2O2 Chlorine is initially removed in the first equation by the reaction with ozone to form chlorine monoxide. Then it is regenerated through

Part Ca)Up until the 1940’s rubber had only been obtained from the latex of rubber trees(Hevea brasiliensis) in plantations situated in tropical areas such as Malaya and Burma. The demand for rubber increased significantly during world war 2 as rubber was needed for tyres of military vehicles and the supply was interrupted by the conflict between the countries. Scientists in Germany and the US developed synthetic polymers that could replace rubber. Even after the war ended the traditional sources

Hypothesis The Researchers believe that using salt and water for solar bottle bulb will be effective it is very cheap and affordable who will use it compared to solar bottle bulb that uses chlorine and water will be more expensive. The researchers are pushing forward to have a successful experiment and better quality for the people who will use. d. Significance of the Study In this study the people will benefit because they can use it

relatively stable and has greater available chlorine than sodium hypochlorite (liquid bleach). Preparation It is manufactured by the calcium process: ~\mathrm{2Cl_2 + 2Ca(OH)_2\longrightarrow \ Ca(OCl)_2 + CaCl_2 + 2H_2O}. "Bleaching powder" is a mixture of calcium hypochlorite (Ca(OCl)2) and the basic chloride CaCl2‚ H2O with some slaked lime‚ Ca(OH)2. Properties Calcium hypochlorite is a yellow white solid which has a strong smell of chlorine. It is not highly soluble in water and is
