calcium | Definition, Properties, & Compounds | Britannica
The metal reacts slowly with oxygen, water vapour, and nitrogen of the air to form a yellow coating of the oxide, hydroxide, and nitride. It burns in air or pure oxygen to form the oxide and reacts rapidly with warm water (and more slowly with cold water) to produce hydrogen gas and calcium hydroxide.
chlorine as disinfectant for water
Chlorine gas can be obtained as fluid gas in 10 bar pressure vessels. It is highly water soluble (3 L chlorine/ 1 L water). To kill bacteria little chlorine is required; about 0,2-0,4 mg/L. the concentrations of chlorine added to the water are usually higher, because of the chlorine enquiry of the water.

Chemistry of Chlorine (Z=17) - Chemistry LibreTexts
Chlorine reacts with most metals and forms metal chlorides, with most of these compounds being soluble in water. Examples of insoluble compounds include \(AgCl\) and \(PbCl_2\). Gaseous or liquid chlorine usually does not have an effect on metals such as iron, copper, platinum, silver, and steel at temperatures below 230°F.

Alloys are produced by coining a pure metal with one or more other elements to form a new substance with desirable properties. (Steel, for example, is a common alloy of iron and carbon.) Magnesium alloys are found in aircraft, automobiles, rockets, luggage frames, portable power tools, cameras, laptop computer casings and mobile phones.

Correct answers: 1 question: Chlorine is a chemical that is widely used in the treatment of pools. it eliminates bacteria and algae by disinfecting & oxidizes other agents like dirt. when chlorine is added to a pool, a reaction occurs in which a weak acid called hypochlorous acid is produced. chlorinated pools are usually treated with a chemical called calcium hypochlorite, ca(clo)2. pure
Water Handbook - Chlorine & Chlorine Alternatives | SUEZ
"Available chlorine" is an expression of the equivalent weights of oxidizing agents, with chlorine gas as a basis, similar to the expression of alkalinity in terms of calcium carbonate equivalents. The term originated from the need to compare other chlorine-containing compounds to gaseous chlorine.
