Compute the energy of the Compton edge as well as the first escape peak in the gamma-ray spectrum of a 2.13 MeV gamma-ray
A mixture containing 0.232 mol He(g), 0.163 mol H2(g), and 0.161 mol N2O(g) is confined in a 22.00 L vessel at a constant temperature. The total pressure is 1.16 atm. Calculate the mole fraction of N2O(g) in the mixture.
Compound a C9H12, undergoes nitration to give three products. The 1H NMR spectrum of A shows a complex three-proton multiplet at 6.92-6.99? And a nine-proton singlet at 2.34. Explain what is the structure of A
The normal freezing point of benzene is 5.5 degrees C. A benzene solution contains 62.5 mg of naphthalene (MW = 128g/mol) per 1.00g benzene. The solution freezes at 3.0 degrees C. What is the molal freezing point constant for benzene
