1) The absorbance of a cationic iron(II) sample solution was measured in a spectrophotometer, but the instrument returned an error because the absorbance was too high. The sample was then diluted by using a pipette to take 100.0 μL of the sample and injecting it into a cuvette already containing 2.00 mL of water (total volume is 2.00 mL + 100.0 μL). The absorbance value of the diluted solution corresponded to a concentration of 6.80Ã10â6 M . What was the concentration of the original solution?
2)What did Rutherford expect to happen when he aimed particles at the gold foil?
Check ALL that apply.
A. | Rutherford expected the particles to react with gold atoms forming a new compound. |
B. | Rutherford expected the particles to stop moving after touching the gold foil. |
C. | Rutherford expected the particles to reflect from the gold foil and return in the opposite direction. |
D. | Rutherford expected the particles to be deflected from their straight paths as they passed through the gold foil. |
E. | Rutherford expected the particles to travel in straight paths through the gold foil. |
