A voltaic cell is constructed based on the following reaction: Sn* (aq) + Pb(s) Sn (s) + Pb?* (aq) a) If the concentration of Sn2+ in the cathode half-cell is 1.00 M and the cell generates an emf of +0.22 V, what is the concentration of Pb2+ in the anode half-cell? b) If the anode half-cell contains [SO,?-] = 1.00 M in equilibrium with PbSO4 (s), what is the Ksp of PbSO4?

Assume the data below was collected for two different sample solutions using the same experimental procedure you carried out. Based on the two lines shown below, which solution (orange data points or blue data points) corresponds to the sample that would look DARKER in terms of how much light goes through the glass. 0.9 y= 4.7713x - 0.0728 R0.99953 0.8 0.7 0.6 0.5 0.4 0.3 0.2 y1.414x - 0.0546 R0.99642 0.1 0.02 0.04 0.06 0.08 0.1 0.12 0.14 0.16 0.18 0.2 0.1 [Concentration, M] orange data points (lower line) blue data points (upper line) Absorbance

Arrange these substance according to how many drops we could add to a penny before the "bubble" popped, FEW DROPS (left-most) to MANY DROPS (right-most). The description labels on the images are small, so use the following legend to identify the materials: A: vegetable oil B: motor oil C: dish soap D: syrup E: honey A CITE EVIDENCE from your Learning Experience and provide REASONING for why you arranged these substances in this order.

Rank the elements or compounds in the table below in decreasing order of their boiling points. That is, choose 1 next to the substance with the highest boiling point, choose 2 next to the substance with the next highest boiling point, and so on.
