Propose a structure for an amine of formula C4H9N, which liberates a gas when treated with NaNO2 and HCl. The 13C NMR spectrum is as follows
Calculate the mass of oxygen dissolved in a 5.00 L bucket of water exposed to a pressure of 1.13 atm of air. Assume the mole fraction of oxygen in air
Calculate the partial pressures of the gases if the total pressure is 2.00atm at a given temperature.
what would the rate constant be at a temperature of 150C for the same reaction described in Part A?
