(a) If the molar solubility of Tl2S at 25 oC is 5.31e-08 mol/L, what is the Ksp at this temperature? Ksp = (b) It is found that 4.68e-06 g of Nd2(CO3)3 dissolves per 100 mL of aqueous solution at 25 oC. Calculate the solubility-product constant for Nd2(CO3)3. Ksp = (c) The Ksp of Ga(OH)3 at 25 oC is 7.28e-36. What is the molar solubility of Ga(OH)3? solubility = mol/L
Make the compounds listed from an alkyl halide having four carbons or less, with no functional groups but it can be branched, or cyclohexane, cyclopentane, or ehylene oxide.
A given mass of radium is over a million times more radioactive than the same mass of uranium
The reaction is first-order in N2O5, with the specific rate constant 6.08 x 10-4/s. Calculate the reaction rate at these conditions. a. [N2O5] = 0.200 mol/L b. [N2O5] = 0.319 mol/L
Betty, in a hurry to finish part 2 of the experiment, did not let the NaOH solution from part 1 cool at all. She just added it to the HCL solution and took the average temperature as the initial temperature of the mixture.
The initial temperature of the calorimeter is 23.0. If 6.30 of is added to the calorimeter, what will be the final temperature of the solution in the calorimeter?
In the lab using conc. HCL and heat, if the solubities of reactant and product were reversed , how would the isomerization be followed. How would one knows when it is complete
In a second experiment, a 1.217 g sample of a compound with the formula C6H14O(l) was burned in the same calorimeter. The temperature increased by 10.08 oC. Use these data, plus the information given below for CO2 and H2O, to estimate the standard..
Which pair is written with the first member having the higher boiling point?
From there, how would I find the moles of salicylic acid in aspirin sample (mol) and the mass of salicylic acid in aspirin sample (g), which should help me calculate the percent purity of aspirin and the percent yield of aspirin in sample. Thank y..
Calculate ?H, q and w when 1.00 mol of helium at 5.00L and a temperature of 298.15K is expanded and heated simultaneously
Tetrahedral complexes of Co2+ are quite common. Use a d-orbital splitting diagram to rationalize the stability of Co2+ tetrahedral complex ions.
In a 1.00 L flask, 3.40 atm of CO reacts with 2.60 atm of O2. Assuming that the temperature remains constant, what is the final pressure in the flask.
