What molarity of aqueous aluminum sulfate solution can be expected to show the same conductivity as 0.030 M Na2SO4 at 36,000 units?
What is the solubility in moles/liter for copper(II) iodate at 25 oC given a Ksp value of 1.4 x 10-7. Write using scientific notation and use 1 or 2 decimal places (even though this is strictly incorrect!).
Calculate the pH of the solution that results when 100.0 mL of 0.15 M NaOH is added to 50.0 mL of 0.25 M HNO3
What is the solubility of BaF2 (Ksp = 1.8x10-7) in pure water in grams per liter? The molecular weight of BaF2 is 175.
Carbonyl bromide decomposes to carbon monoxide and bromine. COBr2 (g) ↔ CO(g) + Br2 (g) Kc is 0.190 at 73?C. If you place 0.500 mol of COBr2 in a 2.00 L flask and heat it to 73 ?C,
The orbital energy of any atomic species depends on factors other than the principle quantum number n and any given energy level in H is more stable than the same level in H+.
The pH in a lake the size of 4.0 km X 7.0 km and an average depth of 100 m is found to be 4.5. Calculate the mass of calcium carbonate that must be added to the lake water in order to raise its pH to 6.0.
Consider a solution formed by mixing 61.0 mL of 0.100 M H2SO4, 26.0 mL of 0.100 M HOCl, 25.0 mL of 0.200 M NaOH, 25.0 mL of 0.100 M Ca(OH)2, and 10.0 mL of 0.150 M KOH.
At 25 degree celcius ,the second order reaction NOCL(g) - NO (g) + 1/2 CL2 (g) is 50 % complete after 5.82 hours when the initial concentration of Nitrosyl chloride is 4.46 ml/L.what time will it take for the reaction to be 75 % complete.
An aqueous solution of ethanol, C2H5OH, is 19.00% ethanol by mass and has a density of 0.9700 g mL-1. Calculate the molarity of the ethanol solution.
This is a fact that Bromine(Br) is larger than chlorine(Cl) but indication of equilibrium constant suggests that a bromo substituent has a less preference for the equatorial position than chloro substituent? Explain it briefly?
