How many kilograms of a fertilizer made of pure P2O5 would be required to supply 1.86 kilogram of phosphorus to the soil
A diprotic acid, H2A, has the following ionization constants: Ka1 = 1.1 multiplied by 10-3 and Ka2 = 2.5 multiplied by 10-6. In order to make up a buffer solution of pH 5.80, which combination would you choose, NaHA/H2A or Na2A/NaHA?
The decomposition of N2O to N2 and O2 is a first- order reaction. At 730°C the half-life of the reaction is 3.58 3 103 min. If the initial pressure of N2O is 2.10 atm at 730°C, calculate the total gas pressure after one half-life.
What do you expect will happen to the position of this equilibrium when the total pressure of the gases in the reaction mixture is doubled by injecting some argon (Ar) while maintaining the temperature constant.
Briefly discuss the importance of the principles of solubility and miscibility when choosing extraction solvents
