Hydrogen sulfide reacts with sulfur dioxide to give sulfur as one of the products. H2S(aq) = S(s) + 2H+(aq).+-2e.
SO2(aq) + 4H(aq) + 4e = S(s) + 2H2O(1)

In this reaction, how many moles of hydrogen sulfide are needed to produce 1 mol of sulfur?
A 1/3 mol
B 2/3 mol
C 3/2 mol
D 2 mol

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.

If you add 10ml of hot water to 10ml of cold water and the change in tempature 8°c calculate how much energy is gained by the cold water
