Explain the MOLECULAR difference between an electrolyte solution and a non-electrolyte solution
Evaluate the specific rate constant for the reaction at the temperature for which the data were obtained. The rate-law expression is rate = k[A][B]2
A block of Iron has a mass of 483 g. What is the mass of a block of Graphite that has the same volume as the block of Iron?
What is the pH of a buffer prepared by adding 0.809 of the weak acid HA to 0.305 of NAH in 2.00 L of solution. The dissociation constant Ka of HA is of is (5.66 X 10^{-7})
The atoms in Barium metal are arranged in a body-centered cubic unit cell. Calculate the radius of a Barium atom if the density of barium is 3.5 g/cm3
Each reaction needs to be balanced and all physical states (s, l, g, aq) noted (you may need to look these up or read the lab to determine the physical states).
What is the expected freezing point of an aqueous solution of 2.62 kg of nitric acid, HNO3 , in a solution with a total mass of 5.91 kg? Assume that the nitric acid is completely ionized.
To what final concentration of NH3 must a solution be adjusted to to just dissolve .060 mol of NiC2O4 (Ksp: 4x10^-10) in 1L if sikution. Neglect the hydrolsis of C2O4 because the solution will be quite basic.
Magnesium reacts with iron(III) chloride to form magnesium chloride and iron. 3Mg(s) + 2FeCl3(s) => 3MgCl2(s) + 2Fe(s)
The molecule iodine monochloride ICl has a diple moment of 1.6 D and a bond length of 2.32 A. What is the effective charge on I in untis of electronic charge e
