Show mathematically that addition of a common ion will decrease the ionization of a weak acid OR a weak base
Even with a perfect shima and a higher field of instrument, the spectrum of 2-methyl-2-hexanol is difficult to interpret. Give two different reasons for this difficulty
Using Tables from the book when needed, determine the volume of 0.280 M NaOH needed to reach the equivalence point in the titration of 41.1 mL of 0.343 M HNO2
Instead of 6 M NaOH being added to the test solution, 6 M HCl is added. How will this affect the test for the presence of ammonium ion in the solution? Explain.
A 145 g aluminum cylinder is removed from a liquid nitrogen bath, where it has been cooled to -196° C. The cylinder is immediately placed in an insulated cup containing 226 g of water at 15.0° C,
Calculate the ionic strength ad all the individual activity coeffcient for all solution in which 0.02 mole of (Feso4) and 0.1 mole of (NH4)2cro4
Description of Chemical Reactions, Why when heating and cooling three different separate substances in open containers does the mass change in two of them (one loss mass; the other gained mass) but stays the same in the third when it is known that..
what is the difference between the solvents used to run TLC's of polar and non-polar lipids?
the calculation of the Ksp value be affected if the endpoint of titration was surpassed (i.e. too much HCl was added)?
13.00 moles of gas are in a 5.00 L tank at 22.6 C. Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane are a = 2.300 L^2*atm/mol2 and b = 0.0430 L/mol.
The delta G for the reaction is 2.60 kj/mol at 25 degrees C. The initial pressures are P H2 = 3.34 atm, P I2 = 0.024 atm and P HI = 0.24 atm.
Calculate the fraction of atoms in a sample of argon gas at 391 K that have an energy of 12.7 kJ
Predict the probability P9v) that a molecule will have a given total velocity of more specifically P(v)dv is the probability that a molecule will have a velocity btwn v and v+dv.
