PROBLEM SET IN STOICIOMETRY II Use separate answer sheet for each item: ( Show your complete reaction) 1.) A mixture of 15.0 grams of Aluminum and 20.0 grams of Sulfur is made to react to form Aluminum sulfide according to the expression: Al + S →Al,Sala (A). Which one is the limiting reactant? (B). How many grams of AlI,S, can be formed? (C). How many grams of the other reactant ae left over? 2.) Given the following expression for the reaction between copper and sulfur, (A). What is the theoretical yield of Cu,S from 75.0grams Cu with an excess of S? (B). If 80.0 grams Cu,S are actually obtained, what is the percent yield? 3. If 0.4352 grams sample of Copper oxide is heated and decomposes into 0.3477 g of copper oxide and an unknown amount of oxygen gas, (A). Calculate the percent by mass of Copper. (B). the percent by mass of Oxygen in t sample. 4.) A 0.1465 grams sample of organic compound containing only C, H, and S underwent combustion to quantitatively yield 0.2075 g Co,, 0.1278 grams H,O, and an unknown amount of SO,. What is the Percent C, H, and S in the compound? 5.) The composition of a compound containing Cd, P, and O, is 63.94% Cd and 11.80% P (by mass). What is the empirical formula for this compound? 6). Using the expression: 2NaOHsa + H,SOal→ Na,SO, (sa + 2H,0 How many grams of NaOH are needed to react with excess H,SO, to prepare 60.0grams of Na,S0,? 7.) How many molecules of H; are present in 7.5 grams of H,? 8.) Calculate the number of Oxygen atoms in 300g CaCo,. 9.)
