E^@ of three metals A, B, C are -1.4 V, + 0.6V, - 3.4V respectively. The reducing power of these metals are in order :
The probability that a student will receive an A, B, C or D grade is 0.40, 0.35, 0.15 and 0.10 respectively. Find the probability that a student will receive : B or C grade.
The probability that a student will receive an A, B, C or D grade is 0.40, 0.35, 0.15 and 0.10 respectively. Find the probability that a student will receive : at most a C grade.
The probability that a student will receive an A, B, C or D grade is 0.40, 0.35, 0.15 and 0.10 respectively. Find the probability that a student will receive : not an A grade.
the protective power of the lyophilic colloids es expressed in terms of gold number, a term introduced by Zsigmondy. Gold number is the number of milli - gram of the protective colloid which prevent the coagulation of 10 mLof red gold sol , when 1 mL of a 10 per cent solution of sodium chloride is added to it . thus smaller the gold number of lyophillic colloid, the greater is the protective power. which of the following statement (S) is / are correct? higher the gold number, more protective power of colloid, Lower the gold number, more protective power, Higher the coagulation value, more the coagulation power, lower the coagulation value, higher the coagulation power.

On addition of one mL of sloution of 10 % NaCl to 10 mL. of red gold sol in presence of 0.025 g of starch the coagultion is just prevented . the gold number of starch is : 0.025, 0.25, 2.5, 25.
If vec a , vec b , vec c , vec d are the position vector of point A , B , C and D , respectively referred to the same origin O such that no three of these point are collinear and vec a + vec c = vec b + vec d , than prove that quadrilateral A B C D is a parallelogram.
The reaction A(g) + 2B(g) to C(g) is an elementary reaction. In an experiment involving this reaction, the initial pressures of A and B are P_A = 0.40 atm and P_B = 1.0 atm respectively. When P_C =0.3 atm, the rate of the reaction relative to the initial rate is:-
Find the area of the triangle ABC where A,B,C are the points (a,0,0), (0,b,0),(0,0,c )respectively, where abc != 0 .
