In the compound aluminum oxide, which is the cation?

Answer:

-Aluminum Oxide: The cation is Al3+ and the anion is O2-. The sum of the charges for aluminum oxide is 2(3+) + 3(2-) = 0. Thus, the formula is Al2O3. An ionic compound is named using the name of the cation followed by the name of the anion, eliminating the word ion from each.

Two identical spoons are electroplated with Ag or Cd through the use of the electrolytic cells. A current of 5.00A was supplied to each cell for 600. seconds, and the masses of the spoons before and after the electroplating were recorded. Write down the mathematical equations can best be used to account for the much larger increase in mass of the spoon electroplated with Ag compared with the spoon electroplated with Cd.

You have two compounds that you have spotted on a TLC plate. One compound is more polar than the other. You run the TLC plate with neat hexanes and find that only one spot moved a small distance up the plate. Next you made a 50/50 mixture of hexanes and ethyl acetate. What might you expect to see on your TLC plate (what would the spots do)?

Arsenate (AsO43-) is structurally and chemically similar to inorganic phosphate (PO43-), and many enzymes that act on phosphate will also use arsenate as a substrate if it is available. However, unlike phosphates, organic compounds of arsenate are kinetically unstable. For example, acyl phosphates (such as 1,3-bisphosphoglycerate) require an enzyme to catalyze phosphate hydrolysis on a biologically relevant timescale, but acyl arsenates hydrolyze almost instantaneously in water without an enzyme.
a) Predict the effect on the net reaction catalyzed by glyceraldehyde 3-phosphate dehydrogenase if phosphate were replaced by arsenate.
b) Write a balanced overall equation for the conversion of glucose to pyruvate in the presence of ATP, ADP, NAD+, and arsenate.
c) Arsenate is extremely toxic to most organisms. Based on your answers above, explain why.
