An unknown amount of Lithium hydroxide is dissolved in 50.0 mL of water. If it take 14.7 mL of a 0.150 M solution of oxalic acid (H2C2O4) to neutralize the lithium hydroxide solution, what is the mass of lithium hydroxide (in grams) that was dissolved in the 50.0 mL of water.
Write a paper on an article and it shows many different compounds and need a better understanding of where each originated and what steps were made in their synthesis.
the ksp of agcl is larger than the ksp of k2cro4,yet k2cro4 is more soluble than agcl. explain the fallaciousness of the statement.
Enough of a monoprotic acid is dissolved in water to produce a 0.0142 M solution. The pH of the resulting solution is 2.51. Calculate the pKa for the acid
Concentrations of Components in an Equilibrium, The following equilibrium process at 686 deg. C. CO2(g) + H2(g) f/r CO(g) + H20 (g)
Using phosphoric acid, what concentrations are needed to give a pH 8.10 solution with an ionic strength of 0.100 M?
What is the molality of a solution prepared by dissolving 413 mg of KBr in 6.45 mL of water at 25.0 0C. The density of water at 25.0 0C is 0.997 g/mL.
Assume that the specific heat and density of the resulting solution are equal to those of water [4.18 rm J/(g cdot {^circ C}) and 1.00 rm g/mL] and that no heat is lost to the calorimeter itself, nor to the surroundings.
The [OH-] = 1.3 x 10^ -6 M for a 0.025 M solution of a weak base. Calculate the value of Kb for this weak base.
What is the volume of 455 mL of oxygen gas at 67.0°C and 300. mm Hg if the conditions are adjusted to 890. mm Hg and 107°C? Assume the amount of gas is held constant.
Which components of an acrylamide gel effects qualities of the final product, and which components affect the speed of polymerization?
Given that the Ka of boric acid is 5.8x10^-10M, what is the pH of a 0.50M boric acid solution? Are there any good approximation available?
You are given a worked wooden item from an archaeological dig believed to date to during the last glaciation. As such, the artifact would be another piece of evidence.
