Treatment of an unknown alkene with Hg(OAc)2 in H2O/THF, followed by a NaBH4 workup, produces an alcohol isomeric to one obtained by hydroboration-oxidation of the same alkene. Reduction of the alkene affords the compound C5H12, while ozonolysis yields an aldehyde, CH3CHO, as one of the products. Deduce the structure of the alkene.
How many kilograms of magnesium can be obtained from 5.96 km^3 of seawater if the initial Mg^2+ concentration is .19% by mass. Remember the density of seawater is 1.04 g/ml
Suggest reasons why recrystallization from water would probably not be suitable procedure for purifying
A star is estimated to have a mass of 1 multiplied by 1036 kg. Assuming it to be a sphere of average radius 6.5 multiplied by 105 km, calculate the average density of the star in units of grams per cubic centimeter.
The atomic mass of Potassium 39 is 38.96371 AMU. Calculate the binding energy for a mass of this nuclide using 1.008665 AMU for the mass of the neutron, 1.007276 AMU for the mass of the proton, 0.00054858 AMU for the mass of the electron
How much energy is required to decompose 765 g of PCl3, according to the reaction below? The molar mass of PCl3 is 137.32 g/mol and may be useful.
Calculate the quantity of heat in calories release when 241.62 g of water is cooled from 80.6°C to 28.0°C.
below which there is too little fuel to support combustion. For propane, the LFL is 2.1 mol-%. What is the mol fraction of propane in the air at the stoichiometric concentration?
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.
What is the concentration of toluene in air produced by vaporizing 1 ml of liquid toluene into clean air to produce a total volume of 100 liters
What molarity of aqueous aluminum sulfate solution can be expected to show the same conductivity
The vessel will contain gases at pressures up to 210.0 MPa. The student's design calls for an observation port on the side of the vessel (see diagram below). The bolts that hold the cover of this port onto the vessel can safely withstand a force o..
