Compound A, C8H10, can give 2 isomeric products upon substitution of an aromatic H by -NO2. The 1H NMR spectrum of A shows 2 two-proton doublets at 7.14 and 7.34 ? and a six-proton singlet at 2.34 ?. What is the structure of A?
Calculate the pH at the equivalence point in titrating 0.100 M solution of sodium hydrogen chromate (NaHCrO_4 )with .080 M NaOH.
Sodium reacts with flourine to produce sodium flouride. If 4.0 grams of sodium reacts with 5.0 grams of flourine, how much NaF can be produced?
nknown gas effuses in 11.0 min. An equal volume of H2 in the same apparatus under the same conditions effuses in 2.56 min. What is the molar mass of the unknown gas
What is the order of a reaction that has the following time and concentration data? Time concentration
for a certain change, the value of change in U is -2.37kJ. during the change the system absorbs 650 joules. how much work did the system do?
One of the chair conformations of cis-1,3-dimethylcyclohexane is more stable than the other by 23.1 kJ/mol. Use this to estimate the energy cost of a 1,3-diaxial interaction between two methyl groups
You use 32.0 mL of NaOH to titrate 100. mL of HCl and 22.2 mL of NaOH to titrate 50.0 mL of 0.0836 M H2SO4. Find the unknown concentrations. NaOH HCl
You decide to use gel filtration. This works brilliantly and you determine that your protein is 80kDa at the same time. But wait! The gene that corresponds to HMD predicts a protein of only 38kDa. What are two potential causes of this discrepancy?
When doing the kinetic trial, Peyton mistakenly omitted the starch solution from the kinetic trials. How will this omission change the appearance of the resultant solution (from mixing solutions A&B) from that of a correctly completed expiernment?..
A solution of ethanol (C2H5OH) in water is prepared by dissolving 60.0 mL of ethanol (density = 0.79 g/cm3) in enough water to make 235.0 mL of solution. What is the molarity of the ethanol in this solution?
The density of acetic acid vapor at the narmal boiling point, 118.5 degrees C, is given as 3.15 g/L (normal boiling point is the boiling point at P =1 atm). a) calculate the fraction of the vapor that is the monomer and the fraction that is the dim..
A 15ml aliquot of this solution was the diluted to 500ml of water. Calculate the final molarity
