Suppose that in the reaction Q + R --> P, only the product, P, is colored.
What happens to the absorbance at the analytical wavelength for P of the mixture as the reaction progresses?
Suppose you do an experiment involving this reaction in which Q is present in large excess of R. If this reaction is first order with respect to R, would the graph of ln A for P versus time be straight line?
imagine you are a water molecule, describe your travels through the many you have been and might go in the future as you make your way around the hydrologic cycle time after time. Include travels through organisms.
Calculate the total pressure if the volume of the reaction container is then (i) doubled; or (ii) reduced 7-fold.
you add 7.3 iron to 25.10 of water and observe that the volume of iron and water together is 26.03. calculate the
What is the pH after 0.150mol of HCL is added to the buffer from part A? Assume no volume change on the addition of the acid.
How much benzoic acid should be formed and will it be pure (in theory)? Is 50mL of water an appropriate volume for this procedure. If not, what is the minimum volume of water required? Use calculations to aid in your explanation.
Explain how the electron configuration of calcium can be determined by changes in I.E. (specifically, the large changes, for example between electron 18 and 19).
