I have read in Silberberg general chemistry that in the periodic table the acidic character increases from left to right, but due to this table, it shows Mn, Tc and Re are exceptions, I wonder why? can anyone explain? Basic-acidic_oxides_periodic_table (1).png(268.96 kB, 2032x1232 - ...
Acidic character of oxides increases as we move from left to right in a period and depends upon oxidation state of central element.
The use of annual or monthly mean values, for example in Table 24.3, conceals large variations in individual rain events. Like sulphate aerosol concentration, sulphate ion deposition has an episodic character. In some remote areas, up to 30% of annual sulphate deposition can come down in one ...
The decreasing order of acidic character of the following is: (I)(II) (III) (IV) View Solution The set with the correct order of acidity is View Solution The correct order of acidic strength is View Solution Doubtnut is No.1 Study App and Learning App with Instant Video Solutions for NC...
(in)stability to the determination of the character of active species and defects under operating conditions. The application of these methods to long-time-scale diffusive processes and reaction networks in highly defective model systems that match those of industrial application is already underway, ...
Co3O4 was investigated by checking the Co 3d, O 2p and Ir 5d pDOS, in which it can be clearly observed that the Ir 5d orbit is substantially overlapped with Co 2p orbit in pDOS, sug- gesting the strong interaction and more covalent character between Co and Ir atoms (Fig. 4f, g)...
ii) First ionisation enthalpy increases from left to right in the periodic table. iii) Electron gain enthalpy increases as the electronegativity of the atom increases. iv) The metallic character increases as the size of the metal atom increases. View Solution Arrange the following groups in ...
(a) Account for the following : (i) The acidic strength decreases in the order HCl gt H2S gt PH3 (ii) Tendency to form pentahalides decreases down the g
(ii) The solubility and the nature of oxides of Group 2 elements. View Solution The metallic character of element of group 14 View Solution How does the basic character of oxides of group 2 elements vary on moving down the group ? View Solution ...
the hydrophilic character, whereas a higher propylene oxy or butylene oxy content increases the hydrophobic character of the additive composition. It has been found that additive compositions of a poly (propylene oxy) or poly (butylene oxy) capped with one or more ethylene oxy units have good ...
