Use retrosynthetic analysis to suggest a way to synthesize 3-hexanol using the grignard reaction
Using a flow diagram, show the separation of a mixture containing p-bromoacetanilide, N-cyclopentyl-N-methyl-N-propylamine (N means the group is attached to the nitrogen of the amine) and m-nitrophenol. Specify the organic solvent and aqueous
The absorbance at 595 nm was 0.78 and,according to a standard curve, corresponds to 0.015 mg of proteinon the x axis. What is the protein concentration of the original solution?
dissolved in water and completely neutralized by the addition of 43.70 mL of 0.303 M NaOH. Calculate the molar mass of the acid, assuming it to be a monoprotic acid.
100.0 ml of 0.100 M acetic acid is placed in a flask and is titrated with 0.100 M sodium hydroxide. An appropriate indicator is used. Ka for acetic acit is 1.7 x 10^-5. Calculate the pH in the flask at the following points in the titration.
If a solution contains 0.60 mol of OH^-, how many moles of H^+ would be required to reach the equivalence point in a titration. Express your answer using two significant figures.
a calorimeter contains 27.0 ml of water at 13.0 circc. when 1.30 g of rm x a substance with a molar mass of 81.0 gmol
What are these Lewis Structures?
How many grams of methane gas (CH4) are in a 15.8 liter sample at 1.2 atmospheres and 27°C? Show all work used to solve this problem.
Write the correct Lewis structure and describe the species geometry for polar HFCCHF.
Diagram the most accurate procedure so you end up with at least 500 uL each of 5 ug/uL, 0.5 ug/uL and 0.05 ug/uL working solutions of BSA.
Compute the molality of a solution containing 327 g glucose(C6H12O6) dissolved in 1.52 L of water. (Assume a density of 1.00 g/mL for water.)
You were given an unknown which gave precipiates with all four test solutions, 1 M H2SO4, 0.25 M (NH4)2C2O4, 1M K2CrO4 and 1M CH3COOH and 1M Na2CO3. Which of the four groups IIA metal cations are deffinitely absent from your unknown?
