What would be an explanation/discussion of product isolation? In this case, we are conduction column Chromatography.
Isooctane is a standard for gasoline octane rating. A sample weighing .5992 g was found to contain .5040 g of carbon and .09515 g of hydrogen. Its molecular mass is 114. Write the empirical and molecular formulas of isooctane (arranging the symbol..
If one cubic centimeter section of a reactor has a macroscopic fission cross section of 0.989 cm-1, and if the thermal neutron flux is 1x10^15 n/cm2 s, calculate the fission rate per cubic centimeter.
A 29.0-g sample of water at 290. K is mixed with 51.0 g water at 340. K. Calculate the final temperature of the mixture assuming no heat loss to the surroundings.
A compound containing only C, H, and O was extracted from the bark of the sassafras tree. The combustion of 50.7 mg produced 138 mg of CO2 and 28.2 mg of H2O. The molar mass of the compound was 162 g/mol. Find out its empirical and molecular formu..
At high temperatures phosgene (COCl2) decomposes to give carbon monoxide CO and Cl2. In a typical experiment, 0.631 g of COCl2 is injected into a flask of volume 472 cc. When equilibrium is established, it is found that the total pressure is 2.175..
The object ofthis problem is to determine V40, the required volume ofthe 40% mixture. Calculate V40 and do a degree-of-freedom analysis.
A pound of coffee beans yields 70 cups of coffee (4 cups = 1 qt). How many milliliters of coffee can be obtained from 1.0 g of coffee beans.
A wedge-shaped tank is filled with water at a rate of 5.00 kg/s. The tank is 4.00 m long and 4.0 m tall, and the angle of the wedge is 90°. The wedge is oriented as pictured, with the point down such that cross sectional area changes with height
Which silver salt will precipitate first? Show calculations to support your answer. What is the concentration of Ag+ when the first precipitate begins to form?
A sodium chloride crystal in a beaker. As water is added the salt dissolves into positive sodium ions and negative chloride ions. Hydration refers to the final state of this process such that the water molecules tend to orient around the ions.
a solution consisting of isobutyl bromide and isobutyl chloride is found to have a refractive index of 1.3931 at 20 degrees celsius. The refractive indices at 20 degrees celsius of isobutyl bromide and isobutyl chloride
