Use the localised electron model to describe the bonding in hydrogen cyanide and phosgene (COCl2)
a) Write a C program that reads marks of 10 students in to a single subscripted array. b) Above marks should be between 0 to 20. Modify the above program to add marks to the array only if the input mark is between the given range. c) Display the values stored in the array
Titration of 0.2121 g of pure Na2C2O4 (134.00 g/mol) required 43.31 mL
of KMnO4.What is the molar concentration of the KMnO4 solution?
Titration of 0.2121 g of pure Na2C2O4 (134.00 g/mol) required 43.31 mL
of KMnO4.What is the molar concentration of the KMnO4 solution? The
chemical reaction is
2MnO4 + 5C2O4+ 16H* ->2Mn+ 10CO2+ 8H2O
Helium gas is contained inside a piston cylinder assembly as shown in the figure. Initially the gas is
having pressure 1 bar and volume 0.01 m3
. Then the current is supplied, and the gas is heated such
that the final pressure is 1.2 bar and the final volume is 0.0145 m3
. 10 % of the electrical energy
supplied to the gas is lost as heat from the cylinder. Determine the followings. If necessary, make
assumption(s) with justification.
(a) How long the current is supplied if process is ideal?
(b) How long the current is supplied if process is real?
describe the preparation of 900 ml of 3 M HNO3 from the commercial reagent that is 70.5% HNO3 (w/w) and has a specific gravity of 1.42
Let X, Y be a independent and identically distributed random variables, each having Poisson distribution with rate parameter λ. Find the probability generating function of W = X + Y and hence the mean and variance of W
The joint density function of the random variables X, Y is given as
f(x, y) = { 0.4 (2x + 3y), 0 < x < 1, 0 < y< 1
0, elsewhere
1)Determine P [ 0.33 < X < 2/3 |Y > 3 /4 ]
