Calculate the de Broglie wavelength for each of the following.a 57 g ball with a velocity of 35. m/s b an electron with a velocity 12% the speed of light.
dilute to mark with water and mix. (You will need the extra volume of this most concentrated solution for further studies.) Record your actual standard concentrations accounting for the dilution as Cstd1, Cstd2, Cstd3, and Cstd4, respectively.
Problem- A 24 hour urine creatinine is diluted 1:10 with saline. The value is too high for accuracy, so the solution is diluted 1:5. What is the final dilution factor
Question- Assign these peaks and create a structure tabular format. Isomers of 8 carbons 8 hydrogens 2 oxygen
The decay of radioactive elements follows first-order kinetics. Therefore, the rate of decay can be described by the same integrated rate equations and half-life equations that are used to describe the rate of first-order chemical reactions.
