entropy
is entropy on moleculare basis relates to the tras.,vib.,and rotational motions?
Can protein act as the buffer? Briefly comment on that statement.
Presence of small concentrations of appropriate electrolyte is necessary to stabilize the colloidal solutions. However, if the electrolytes are present in higher concentration, then the ions of the electrolyte neutralize the charge on the colloidal particles may unite
Briefly describe the difference in the Mendeleev’s table and modern periodic table?
Energy changes in some chemical reactions can be used to deduce the energies of chemical bonds. Our understanding of the molecular basis of thermodynamic properties is extended when we ask why the enthalpy change for a reaction is what it is. We deduce,
The coordination number of a cation engaging a tetrahedral hole is: (a) 6 (b) 8 (c) 12 (d) 4 Answer: (d) The co-ordination number of a cation occupying a tetrahedral hole is 4.
Briefly state the wavelengths which the human eye can see?
Give me answer of this question. When a non-volatile solute is dissolved in a solvent, the relative lowering of vapour pressure is equal to: (a) Mole fraction of solute (b) Mole fraction of solvent (c) Concentration of the solute in grams per litre
An extension of the kinetic molecular theory of gases recognizes that molecules have an appreciable size and deals with molecule-molecule collisions. We begin studies of elementary reactions by investigating the collisions b
Average covalent radii can be assigned on the basis of molecular structures. The accumulation of structural data by spectroscopic studies and both electron and x-ray diffraction studies allows one to investigate the possibili
