Predict the reaction at both the anode and cathode for the electrolysis of molten NaF(in molten NaF,only the ions are present,ie no water is present).
a solution of silver nitrate can be used to prepare photograpic film. if 50.00 g silver nitrate is used to make 500 ml
A 354 gram sample of C6H12O6 has a pressure of 648 torr at 31°C. What is the volume (L) of the container?
To ensure the impurity does not exceed this amount, how much water must be added to the solution before the temperature is dropped if the initial solution weighed 500 kg? How much Na2S2O2 will be generated in this process?
A 32.0 g sample of liquid water at 21.0C absorbs 2276 J of heat energy. What will be the final temperature of the water? The specific heat of liquid water is 4.185 J/gC.
The osmotic pressure of blood at 27 degrees Celcius is 7.7 atm. A solution that is given intravenously must have the same osmotic pressure as the blood.
How many millilitres of 0.200 M HCl must be added to 50.0 mL of a 0.200 M solution of NH3 in order to prepare a buffer that has a pH of 8.60? Kb of NH3 = 1.8 x 10-5.
