How many moles of each reactant are used in the epoxidation of cholesterol? Assume the 3-chloroperoxybenzoic acid is 80% pure.The reactants in this experiment were 3-chloroperoxybenzoic + Cholesterol
The next question was this: "What is the PH at it's equivalence point? AS part of your answer, define equivalence point. What does it mean for a substance to be at its equivalence point?"
Calculate the molarity of a solution made by dissolving 0.150 mol Na2SO4 in enough water to form exactly 760 mL of solution.
the equivalence point i know you need to use [A-]= moles of HA/(vol water added+vol NaOH added) and believe moles of HA=5.39x10^-3
a tank contains 150.0 g of co2 and 24.0 g o2 at a total pressure of 4.25 atm and a tempature of 25.0*C. Calculate the partial pressure of O2.
The temperature of a 2.25 L sample of gas decreases from 35C to 20C. What is the new volume?
what is the net ionic equation potassium hydroxide and iron(III) nitrate.
CaCN2 + 3H2O -> CaCO3 + 2NH3 . How much NH3 is produced if 187 g of CaCO3 are produced?
A United Nations toxicologist studying the properties of mustard gas, S(CH2CH2Cl)2, a blistering agent used in warfare, prepares a mixture
Consider 2 Al + 6 HCl → 2 AlCl3 + 3 H2 , the reaction of Al with HCl to produce hydrogen gas. This reaction has a yield of 82.5 percent. How much HCl are needed to produce 14.0 L of H2 at 351 K and 1.11 atm
A suitable storage place must be geologically stable long enough for the activity of plutonium-239 to decrease to 0.1% of its original value.
The hydrogen carbonate ion can act as both an acid and a base. Write out two equations which demonstrate this and calculate (or look up) the equilibrium constants for both expressions
What is the concentration of hydrogen ions in a solution containing 0.321 M HOCN (cyanic acid) and 0.223 M (NaOCN) (sodium cyanate)? The ionization constant of cyanic acid is 3.5 × 10-4.
