Carbon and oxygen combine to from two oxides, carbon is respectively ` 12: 16` and ` 12 : 32`. These figures illustrate the :

Carbon and oxygen combine to form two oxides, carbon monoxide and carbon dioxide in which the ratio of the weight of carbon and oxygen is respectively 12:16 and 12:32 . These figures illustrate the : (a)law of multiple proportions (b)law of reciprocal proportions (c)law of conservation of mass (d)law of constant proportions

Percentage of oxygen and carbon dioxide in air is respectively

The pair having oxide and carbonate ore respectively

Nitrogen and oxygen combine to form many oxides. In some oxides, 14 g of nitrogen combine with either 16 g of oxygen or 32 g of oxygen. In some other oxides, 28 g of nitrogen combine with 16, 48, or 80 g of oxygen, (i) What are the formulae of the oxides ? (ii) What law of chemical combination does the formation of these compounds illustrate ?

Carbon and oxygen form two compounds. Carbon content in one of them is 42.9% and in the others is 27.3%. The given data is in agreement with

The valancy of carbons is generally 4 , but its oxidation state may be -4, -2, 0, +2, -1 , etc. In the compounds containing C, H , and O , the oxidation number of C is calculated as Oxidation number of C= (2n_(O)-n_(H))/(n_(C )) Where n_(O), n_(H) and n_(C ) are the numbers of oxygen, hydrogen, and carbons, atoms, respectively. In which of the following compounds is the oxidation state of carbon is zero?

Average oxidation number of carbon in C_3O_2,Mg_2C_3 are respectively.

The vapour density of carbon dioxide [C=12,O=16]

Carbon reacts with oxgen forming carbon monoxide and/or carbon dioxide depending an availablity of oxygen. Find moles of each product obtained when 160gm oxygen reacts with (a) 12 g carbon (b) 120 g carbon (C ) 72 g carbon.

The distance between the carbon atom and the oxygen atom in a carbon monoxide molecule is 1.1 Å . Given, mass of carbon atom is 12 a.m.u. and mass of oxygen atom is 16 a.m.u., calculate the position of the centre of mass of the carbon monoxide molecule
