Ammonia reacts with oxygen according tot he following equation: 4NH3+5O2=4NO+6H2O deltaHrxn = -906kJ Calculate the heat (in kJ) associated with the complete reaction of 155g of NH3.
The Milikan experiment is important because it determined the of an . Using Thomson's and Milikan's the of an was determined. Rutherford's experiment is important because it clearly demonstrated that the is mostly
Each of four compounds shown has one signal in the aromatic region and one signal in the alkyl region of its H NMR spectrum. Use the integral values to determine which compound's H NMR spectrum is shown below
In this experiment we used ortho-vanillin and p-toluidine to form the imine. Why does the reaction mixture turn into a liquid when the ortho-vanillin and p-toluidine are initially mixed? What is the name or melting point of the product?
How would you separate a mixture of eugenol and cholesterol
When heated, ammonium carbonate decomposes as follows. NH4CO2NH2(s) -> 2NH3(g)+CO2(g) At a certain temp, the equilibrium pressure of the system is 0.318 atm. Calculate Kp for the reaction.
