1. Why do acid- and base-catalyzed elimination reactions often result in a mixture of products? Be specific. Hint - there is more than one reason.2. Why is the formation of substitution products by reaction of bisulfate on the carbocation not a reaction of concern?
What is the magnitude of the change in pH when 1.8 g of NaOH is added to 1.00 L of a solution that is 0.100 M in NH3 and 0.100 M in NH4Cl?
A 4.305-gram sample of a nonelectrolyte is dissolved in 105 grams of water. The solution freezes at -1.23°C. Calculate the molecular weight of the solute. Kf for water = 1.86°C/m.
A bone sample with 2.8 g of carbon has 17.4 disintegrations per minute. How old is the bone sample in years. What percentage of the atoms of carbon in the biosphere are C-14?
Derive Eh-pH equations based on the progressive oxidation of Mn to form oxides starting with metallic Mn. b) Plot these equations in coordinates of Eh and pH
To the organic chemist, mass spectrometry is especially useful in the determination of the structure of a new compound because it provides information about
Is it possible to convert Calcium Carbonate (CaCO3)into Calcium Oxide (CaO), mixing CaCO3 with water and vinegar and boiling this mixture?
The atmospheric pressure in the room when the measurement was made was 628 mmHg and the temperature was 36.0 degrees C. What is the density of the gas?
A 350 mL air sample collected at 35 degrees C has a pressure of 550. mmHg. What pressure will the air exert if it is allowed to expand to 425 mL at 57 degrees C?
Carry out a calculation that would show only Al(OH)3, but not Mg(OH)2, will form precipitate in a solution that contain 0.10 M Al3+ and 0.10 M Mg2+ if the solution is buffered at pH = 9.00.
the density of plutonium metal is 19.84 g/cm3 , and the density of plutonium (IV) oxide is 11.46 g/cm3. over a period of 7-10 years, a 2.5-kg sample of plutonium metal stored at Los Alamos National Laboratory in New Mexico was converted to plutoni..
An individual's blood alcohol content (% alcohol in blood as measured mass per volume = mass of alcohol per volume of blood) was 0.15. If we assume the individual drank all of the alcohol at once
Several rate constants were measured for a particular reaction at several temperatures. It was found that k = 0.0173 at 923 K, and k = 0.00919 at 773 K. What is the activation energy, Ea , for this reaction?
