Give the structure that corresponds to the following molecular formula and 1H NMR spectrum: C7H12Cl2: ? 1.07 (integral = 6203, s); ? 2.28 (integral = 1402, d, J = 6 Hz); ? 5.77 (integral = 700, t, J = 6 Hz). Note: The integrals are given in arbitrary units.
What sign. info about atomic structure came from the Millikan experiment using charged oil drops
How much potassium nitrate has to dissolve in water to absorb 118 kj of heat? Lattice E is -163.8kcal/mol and heat of hydration is -155.5 kcal/mol.
A metal, M, was converted to the chloride, MCl2. Then a solution of the chloride was treated with silver nitrate to give silver chloride crystals, which were filtered from the solution.
Carbonyl fluoride, COF2 , is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride
the equivalence point occured at 4.67 mL of HCl. Calculate the pH at 0.00 mL of added HCl and at 2.00 mL of added HCL
Ideal gas law and meteorological balloon, Balloons are still used to deploy sensors that monitor meteorological phenomena and the chemistry of the atmosphere. It is possible to investigate some of the technicalities of ballooning by using the perf..
The density of an unknown gas is 2.00 grams per liter at 3.00 atmospheres pressure and 127 degrees C. What is the molcular weight of the gas?
dilute to mark with water and mix. (You will need the extra volume of this most concentrated solution for further studies.) Record your actual standard concentrations accounting for the dilution as Cstd1, Cstd2, Cstd3, and Cstd4, respectively.
Rate Law for Proposed Mechanism, Consider the reaction 2NO(g) + O2 ---> 2NO2 (g). The following mechanism has been proposed to explain the experimental rate law
