Calculate the pH of 100. mL of 0.28 M NH3 before and after the addition of 4.5 g of NH4NO3, and account for the change. Assume that the volume remains constant. What is the pH before and after the addition of NH4NO3
Ksp for PbCrO4 at 25oC is 2.0 x 10-14. A sample of 1.000 mg of PbCrO4 is added to 1.0 L of water at this temperature.
ALso suppose that an equal Vmax is possible with both of the substrates. Which substrate will show a greater rate of rection at 1 x 10^-3 M. Which substrate will show a greater rate at 1 x 10^-2 M. What will be the effect of addition of B on the r..
For the gas phase decomposition of t-butyl alcohol, (CH3)3COH (CH3)2C=CH2 + H2O the rate constant at 811 K is 1.05E-3 /s and the rate constant at 846 K is 5.64E-3 /s. The activation energy for the gas phase decomposition of t-butyl alcohol is
Assume that the heat capacity of water for the temperature rangere in the heat exchanger is constant at 7.54x10^-2 kJ/mol C) What is the temperature of water leaving the heat exchanger?
The resolution limit of a microscope is approximately equal to the wavelength of light used in producing the image. Electron microscopes utilize an electron beam in place of photons to produce much higher resolution images, about 0.22 nm in modern..
What fraction of the original reactant concentration will remain after 2.0 hours?
what happens to NH3+H2O=NH4+OH when you add NH4Cl?. what type of change is this, which way is the equilibrium shift, and please explain.
Carbonyl fluoride, COF2, is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, CF4 via the reaction
