I asked this yesterday for 50 points, so you can still answer that too. The following thermodynamically favored reaction takes place in an acidified galvanic cell.

O2(g) + 2 H2S(g)  2 S(s) + 2 H2O(l)

a. What is the half reaction that takes place at the anode?

b. What is the half reaction the takes place at the cathode?

c. Calculate the standard cell potential, Eo

cell.

d. What must the partial pressures of the reactants be in order to produce the

voltage in part c?

1.aluminum chloride (alcl3), and sodium hydroxide (naoh) can react to form aluminum hydroxide (al(oh)3) and sodium chloride (nacl).    you have 13.4 g of aluminum chloride and 10.0 g of sodium hydroxide. answer the following questions: •what is the balanced equation for this reaction? •if you use all 13.4 g of aluminum chloride, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •if you use all 10.0 g of sodium hydroxide, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •how many grams of aluminum hydroxide will actually be made?     which reagent is limiting? explain your answer.

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?
