Calculate the molar solubility of AgBr in a 1.00 M aqueous solution of ammonia. Then calculate the solubility of AgBr in pure water, and compare the two solubilities. (Ksp for silver bromide is 7.7x10 -13 and Kf for Ag(NH3)2+ is 1.6x10^7)
10.0 grams of sodium bicarbonate reacts with 50.0 mL of 2 M acetic acid, what is the limiting reactant? what reactant is in excess, and by how much? what volumeof carbon dioxide gas would form?
Determine the molecular weight of a compound given the gas phase data: mass of 11.8 g, temperature of 39.1 C, pressure of 630 torr, volume of 1.31 L.
Calculate k, Calculate also how long it would take for half of A to react. assume pseudo first order with k'=k[OH-], since [OH-] is in great excess.
For the reaction 2A + B --> 2C, if B is initially 4.0M and 2min later is 3.0M, what is the rate of appearance of C?
What mass of ice at 0C must be added to 45g of water at 20C to cool it to the final temperature of 10C?
if 1.500 g of solute that has a molar mass of 125.0 g were dissolved in 35.00 g of camphor, what would be the resulting freezing point of the solution?
Determining Copper in Brass, 1st I titrated Na2S2O3 and determined the molarity to be 0.164. I am having trouble with the calculations for the dissolution of brass.
Li is in row 2 of the periodic table, Na is in row 3, and K is in row 4. How do their row numbers affect how their electron configurations end.
A certain quantity of a gas occupies 61.3 mL at 68 ?C. If the pressure remains constant, what would be the volume of the gas at 128 ?C?
A 24.0 g sample of nitrogen gas reacts with an excess of hydrogen gas to give an actual yield of 3.85 g NH3. What is the percent yield for this reaction? Reaction: N2(g) + 3 H2(g) ? 2 NH3(g)
We are asked to construct an energy level diagram (molecular orbital) for the molecule SO. We are then asked to comment on the ionic species of SO - bond order, bond distance etc. So far so good.
How long would it take for 1.50 mol of water at 100. 0C to be converted completely into steam if heat were added at a constant rate of 16.0J/s ?
