An unknown is believed to be an alcohol because the IR spectrum showed broad absorption at 3200-3500 cm-1 and no absorption in the 1700-1750 cm-1 region. The H NMR spectrum showed a number of signals in the 1-5 region. What can be done experimentally to identify the OH proton in the NMR spectrum?
How many grams of dry NH4Cl need to be added to 2.10 L of a 0.500 M solution of ammonia, NH3 , to prepare a buffer solution that has a pH of 8.76? Kb for ammonia is 1.8*10 ^-5.
A laboratory method of preparing oxygen gas involves decomposition of solid potassium chlorate. The products of the reaction are solid potassium chloride and oxygen gas.
In some solar-heated homes, heat from the sun is stored in rocks during the day and then released during the cooler night. (a) Calculate the amount of heat required to raise the temperature of 78.7 kg of rocks from 25.0°C to 43.0°C.
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.
