Treatment of 4-chloro-1-butanol with one equivalent of lithium diisopropylamide (LDA) as a base leads to rapid formation of a compound with the molecular formula C4H8O. Propose a structure and a complete arrow pushing mechanism for its formation.
Write the structures for the major monobromination products that would be formed from each of the following substrates used. Explain your predictions.
a) what is the ratio of conjugate base to conjugate acid after 100 ml of 1M HA is adjusted to a pH of 8? b) under the conditions in part a, how many moles of HA are present? How many moles of A- are present? c) What is the pH of the solution descr..
Amphetamines in urine can be confirmed by mass spectroscopy at a concentration of 500 ng/mL. Assuming a urine density of 1.025 g/mL, what is this concentration in parts per million
The initial temperature of the calorimeter is 20.7oC. If 6g of CaCl2 is added to the calorimeter, what will be the final temperature of the solution in the calorimeter?
what is the chemical calculation to figure out the following: calculate the new molarity if the following dilution is made (assuming the volumes are additive): 25.0 mL of water is added to 10.0 mL of 0.251 M CaCl2 solution.
How much heat energy, in kilojoules, is required to convert 65.0g of ice at 18.0 degrees celcius to water at 25.0 degrees celcius.
the half-life of tritium 31h is 12.3 years. if 47.0 mg of tritium is released from a nuclear power plant during the
methyl alcohol (CH3OH) is made by reacting carbon dioxide with H2. Starting with 2.5g of H2 and 30.0 L of Co, what mass of methyl alcohol could be produced at STP.
A sample of 1.0 mole of a perfect gas with cp= 20.8 J K-1 is initially at 3.25 atm and 310K. If it undergoes reversible adiabatic expansion until its pressure reaches 2.50 atm. Calculate the final volume and temperature and the work done.
Whats the reduced mass of CO2. I know how to do it for CO but since its 3 molecules do you go m1+m2+m3/m1m2m3 or is m2 just 32
