Use the equilibrium constants to calculate \DeltaGo for the formation of [Cr(NH3)6]2+, [Cr(en)3]2+, and [Cr(dien)2]2+ from [Cr(H2O)6]2+ and NH3, en, or dien, respectively.
R=8.314 J/mol*K
If 141 mL of wet H2 is collected over water at 24°C and a ba?rometric pressure of 738 torr, how many grams of Zn have been consumed.
The molar mass of cellulose is approximately 6.0 x 10^5 g/mol and the molar mass of a soluble starch is on the order of 4.0 x 10^3 g/mol. The monomer unit in both of these molecules has the emperical formula C6H10O5.
If Ka is 1.85 x 10^-5 for acetic acid, calculate the pH at one half the equivalence point and at the equivalence point for a titration of 50 mL of 0.100 M acetic acid with 0.100 M NaOH.
How much heat is required to warm 1.50 L of water from 30.0 C to 100.0 C? (Assume a density of 1.0g/mL for the water.)
if I weigh KHP to use in an experiment (to titrate with NaOH ) on a triple beam balance opposed to analytical scale to eventually find molar mass of unknown NH4 salt, what effect, if any, would this have on the accuracy of final results
A 4.50-g sample of LiCl at 25 C dissolves in 25.0 mL of water also at 25 C. The final equilibrium temperature of the resulting solution is 60.8 C. What is the enthalpy, change of enthalpy, of LiCL expressed in kj per mole?
using a sample having 1.50ml of nitroglycerinng that has density1.592gml then calculate how many total moles of gas are
Hydrogen gas can be prepared by reaction of zinc metal with aqueous HCl : Zn(s) + 2HCl(aq) = ZnCl2 (aq) + H2 (g). How many liters of H2 would be formed at 530mm Hg and 16C if 27.0g of zinc was allowed to react
Which one of the following molecules has tetrahedral geometry?
In an electrolysis cell similar to the one employed in this experiment, a student observed that his unknown metal anode lost 0.238 g while a total volume of 84.90 mL of H2 was being produced.
start with 4-cyclopentylphenol and react with NaOH, CH3I, NBS, heat show each step to get the final product.
