is given credit for the discovery of oxygen. Later work showed the new gas to be a constituent of nitre, a common name forpotassium nitrate(KNO3), and, accordingly, it was named nitrogen by the French chemist Jean-Antoine-Claude Chaptal in 1790. Nitrogen first was considered achemical elemen...
(additional information:the molar mass of water is about 18 g/mol,which means that in 18 g of water the number of molecules equals to the Avogadro constant,6.02X10.One molecule of water ,H2o consists of two atoms of hydrogen and one atom of oxygen.Hydrogen has one electron,oxygen has 8...
Which has maximum number of atom? The Avogadro's number is 6.022×1023atoms. Thus, carbon has a maximum number of atoms.Which has maximum number of atoms of oxygen? Thus there are two moles of atoms present in \[12.044 \times {10^{23}}\] molecules of carbon dioxide. Thus, the ...
the stabilization of the initially formed zwitterion increases due to coulombic attraction of the nonbonded amine nitrogen atom and carbonyl substrate oxygen atom, while, on the other hand, the zwitterion is destabilized due to weakening of the N-C bond between the nucleophile and the substrate. ...
A salt is formed due to the reaction between an oxy acid containing chlorine and a base containing a monovalent metal of atomic mass x. The number of oxygen atoms in one molecule of the acid is more than the corresponding 'ic' acid. Calculate the molecular mass of the salt. View Solution...
Applicability of the emission spectroscopy technique in calculating the concentration of chlorine atoms in a chlorine-oxygen plasma was shown by comparing experimental and calculated relative intensities of the 452.62-nm chlorine line ( 5 p 2 p 3/20 4 s 2 p 3/2 transition, excitation potential ...

The 17O chemical shifts of simple aliphatic ethers were studied, and the additivity substituent increments for carbon atoms in the alkyl groups were determined. The additivity parameters were used to establish a linear correlation with experimental data for a series of aliphatic ethers, alcohols,...
