Combined chlorine

Phosphorus and chlorine combine directly to form either the trichloride or the pentachloride depending on the relative amounts of phosphorus and chlorine used. 

A diagrammatic illustration of the effect of an isotope pattern on a mass spectrum. The two naturally occurring isotopes of chlorine combine with a methyl group to give methyl chloride. Statistically, because their abundance ratio is 3 1, three Cl isotope atoms combine for each Cl atom. Thus, the ratio of the molecular ion peaks at m/z 50, 52 found for methyl chloride in its mass spectrum will also be in the ratio of 3 1. If nothing had been known about the structure of this compound, the appearance in its mass spectrum of two peaks at m/z 50, 52 (two mass units apart) in a ratio of 3 1 would immediately identify the compound as containing chlorine. 

C06-0107. Phosgene (CI2 C I O) is a highiy toxic gas that was used for chemical warfare during World War I. Use the bond energies in Table 6 2 to estimate the energy change that occurs when carbon monoxide and chlorine combine to make phosgene. C I 0(g) + Cl2(g) CI2 C I 0(g)... 

We have learned (Chap. 7) that some reactions occur under one set of conditions while an opposite reaction occurs under another set of conditions. For example, we learned that sodium and chlorine combine when treated with each other, but that molten NaCl decomposes when treated with electricity ... 

Explanation Chlorine combined originally to chlorobutol is being converted by hydrolysis in the presence of sodium hydroxide to ionic chloride that may be estimated quantitatively by Volhard s method in the presence of nitrobenzene. 

Chlorine combines with oxygen, producing four different types of oxides ... 

Chlorine combines with numerous other elements as well. Hydrogen and chlorine gases are extremely explosive when mixed, and they produce hydrogen chloride (HCl) that, when dissolved in water, results in hydrochloric acid Hj + Cl 2HC1. 

Chlorine combines with hydrogen forming hydrogen chloride, HCl. The reaction occurs rapidly when exposed to hght, involving a photochemical chain initiation step. 

Halogens react with the metal at elevated temperatures. Fluorine reacts with ruthenium at 300°C forming colorless vapors of pentafluoride, RuFs, which at ordinary temperatures converts to a green solid. Chlorine combines with the metal at 450°C to form black trichloride, RuCF, which is insoluble in water. Ru metal at ambient temperature is attacked by chlorine water, bromine water, or alcoholic solution of iodine. 

In comparatively rare cases, two molecules combine to form only one new molecule thus a molecule of carbonic oxide and one of chlorine combine to form one molecule of carbonic oxydiohloride or phosgene gas but the union is oven here essentially atomic for after combination both the oxygon and chlorine are directly united with the atom of carbon ... 

In 1842, T. Andrews1 pointed out that although moist chlorine combines energetically with zinc, copper, and iron-filings, perfectly dry chlorine has no action whatever at ordinary temp.,. . . and the same remarks may be applied to the behaviour of dry bromine in contact with dry metals. Indeed, thoroughly dry chlorine is somewhat inert chemically, and it has no appreciable action upon bright metallic sodium, copper, etc. Dried chlorine scarcely acts at all upon, dry silver ... 

Since AgC103=AgCl + 30, if 0 = 16, it follows that the eq. wt. x of silver chloride must be 25-0795 8 + 16=74 9205 x, where x= 143 395. But 100 parts of silver are eq. to 32 8445 parts of chlorine, and henco 132 8445 parts of silver chloride will correspond with 132 8445 143 395 = 100 x, or = 107 942 parts of silver. Similarly for chlorine, since 132 8445 parts of chlorine unite with 107 942 parts of silver, 143 395 parts of silver chloride will contain 35 453 parts of chlorine. Hence, if 0 = 16, 0=36 463. Again for sodium, 32 8446 parts of chlorine combine with... 

It may appear on first consideration that neutral sulphite of lime, which is very little soluble in water, could have but little effect on the chlorine combined with the fibre but the fact that hydrochloric acid dissolves ueutral sulphite of lime with formation of soluble bisulphite of lime, will readily explain its action. Now hydrochloric acid is invariably gaueratad. whenever ohlorine gas acts as a decoloring agent on organic substances. 

Chlorine combines with the gas when the mixture is exposed to sunlight or when the sulphur dioxide is employed in solution in acetic acid or in camphor, the product being sulphuryl chloride 3 no combination occurs in the dark in the absence of a catalyst. In the presence of water the products are sulphuric acid and hydrochloric acid.4 Bromine does not combine in this manner, nor does hydrogen chloride, the freezing-point curve of the latter with sulphur dioxide showing only the formation of a eutectic mixture.5... 

Two explanations are possible of the first phenomenon either the water might form a catalytically active film over a surface, saturation of this film being complete at a very low partial pressure of the vapour or the water might combine with some reactant, such as a chlorine atom in the hydrogen-chlorine combination, present in such small amount, and having such a long life, that all of it would be certain to meet with water molecules before... 

LOWER A BURNING CANDLE INTO A BOTTLE OF CHLORINE GAS. A DENSE SMOKE OF CARBON IS FORMED. THE CHLORINE COMBINES WITH THE HYDROGEN OF THE CANDLE AND SETS THE CARBON IN IT FREE AS SOOT. 

Pure Rubber and Sulphur and Chlorine combined with it.— In the residue from the preceding determination, that is, in the part insoluble in alcoholic potash, the pure rubber and the sulphur and chlorine combined therewith may be determined by the following methods. 

Sulfur and chlorine combine in various proportions forming S2CI2, SCI2, and SCI4. Draw the Lewis structures of these molecules and, using VSEPR, predict their shapes. 

Phosphorus and chlorine combine to form two different compounds. In one compound, 3.88 g of phosphorus combines with 13.28 g of chlorine. In the other compound, 1.32 g of phosphorus combines with 7.56 g of chlorine. Do these data support the law of multiple proportions Show your work. 

Chlorine is abundantly available in NaCl and in saltwater. Hence, the quantity of chlorine combined in these natural sources is enormous. The Great Salt Lake contains 23% salt, and the Dead Sea contains about 30%. Chlorine also occurs in a few minerals, but the abundance of naturally occurring salt water makes these of little importance. 

Thiophosphoryl chloride decomposes when passed through a red-hot tube, giving PC13, S and S2C12.10 An excess of chlorine combines with both the other elements, according to the equation... 

Chlorine gas workers Whole body < 1.0 (average) NR Short-term exposure to high concentrations of chlorine combined with occasional long-term exposure to low concentrations might be associated with decreased maximum midexpiratory flow long-term exposure to low concentrations of chlorine did not appear to have such an association. Chester et al. 1969...
