Identify the reagents you would need to make the following substance via Grignard synthesis, and briefly describe your synthetic strategy.
tim and a friend left a campsite on a trip down a river in a canoe maintaining a constant speed of 4 miles per hour.
suppose 45.0g of water at 85 C is added to 105.0 g of ice at 0 C. The molar heat of fusion of water is 6.01 kJ/mol, and teh specific heat if water is 4.18 J/g C. on this basis of these data (a) what will be the final temperature of the mixture and..
For analysis, a short peptide seven residues long is treated with FDNB, followed by complete acid hydrolysis and amino acid chromatography. What are the products of these steps. What kind of information can be obtained by amino acid chromatography..
Compare the experimental mole ratio of NaHCO3 to NaCl with the theoretical mole ratio. Explain the difference. The experimental mole ratio is 1:1.
Calculate the expected change in temperature for 1.7 g of NH4NO3 dissolved in 50.0 mL of H2O. Assume that the calorimeter absorbs no heat.
Methylamine (CH3NH2) is a weak base. In a 0.100 M solution, 6.30% of the base is ionized. What is its Kb
A metal forms the fluoride MF2. Electrolysis of the molten fluoride by a current of 3.86 A for 16.2 minutes deposits 1.07 (backwards "g") of the metal.
A concentration cell is constructed which contains two Ni(s)-Ni2+(aq) half cells. The first half cell has [Ni2+] = 1.35 M, and the second half-cell has [Ni2+] = 3.75 x 10^-4 M. Which half cell is the cathode of the cell and what is the cell potenti..
The solubility of silver chromate, which has a Ksp equal to 9.0e-12 at 25 degrees celsius, is determined in water and in two different solutions. Predict the relative solubility of silver chromate in the three solutions
A chemist must dilute 80.5mL of 126mM aqueous sodium thiosulfate solution until the concentration falls to 110.mM . He'll do this by adding distilled water to the solution until it reaches a certain final volume.
