a. How can a colloidal solution and true solution of the similar colour be distinguished from each other?
b. Give four applications of adsorption
calculate the surface coverage obtained after exposure to a pressure of 10 torr of CO for 20s at 300K. sticking probability of CO is 0.9
Can we vary the pressure while phases remain in equilibrium? Consider a system containing only NH 4 Cl(s), NH 3 (g), and HCl(g). Assume that the equilibrium NH 4 Cl(s) ↔ NH
Lowest sum rule - iupac system of nomenclature previously it may be noted that, the numbering of the parent chain consisting of two or more substituents was done in such a way
A Tris buffer at pH 6.0 (here "Tris" is a nickname use for Tris hydroxymethyl amino methane). For the given pK A table is Tris a compound you would select for a buffer at pH 6.0?
How can we control the product yield of the Benkeser reaction?
Q. Show properties of the Borax? Salts of boric acids are known as borates. As said earlier, hydrated borates occur naturally, e.g., borax, Na 2 B 6 0 11 . 5H 2 0, kernite, Na
Q.How can we determine Concentrations of Solutions? Ans. The concentration of a solution is the quantitative expression of the amount of solute dissolved in the solution.
If n+l= 6 , then total possible number of subshells would be: (1) 3 (2) 4 (3) 2 (4) 5 Ans: 3
