What is the net ionic equation for the reaction between Fe3+(aq) and Na2S(aq)?

Applying a voltage of 8.00 V, moves the beam 3.00 cm (in the direction an electric field moves the beam). If it requires a magnetic field of 27.0 mT, to balance an electric field of 8.00 V, use the equation below to determine the charge-to-mass ratio.

Using the picture of the detector locations, which of the following charts would you expect to be produced from the Rutherford experiment for the number of alpha particle hits.  

If you obtained the following values for the charge of an electron, find the average charge on one electron and use that value to determine the mass of the electron. Droplet Calculated charge on one electron 1 1.591 × 10-19 C 2 1.445 × 10-19 C 3 1.652 × 10-19 C  

In which direction does the application of an electric field move the beam in the Thomson Cathode Ray experiment?

If you calculated the charge-to-mass ratio for an electron to be 1.81 × 1011, and the accepted value is 1.76 × 1011, what is your percent error?

Which item is the detector in the Thomson Cathode Ray Experiment?  

Suppose you found that the total charge (Qtot) on an oil droplet was 11.42 C. If the accepted charge on an electron (e) is 1.602 × 10-19 C, how many electrons are on the droplet?
