Need 2-8. All of it actually.
2) Lithium nitride is a proposed hydrogen storage medium. It is formed by the reaction of lithium metal with nmitrogen gas: Suppose you start the reaction with 5.00 g of lithium, how many grams of lithium nitride do you expect to get? (3) Tantalum (V) bromide reacts with oxygen gas to form tantalum (V) oxide and bromine as below: 4 TaBr, ol + 5 0ng' â 2 Tuo, (s. + iO Br1@ Suppose 100.0g of tantalum (V) bromide are used for this reaction. How many grams of tantalum (V) oxide will be produced? (4) Indium metal reacts with sulfur to form indium sulfide as below: Suppose you need to produce 50.0g of indium sulfide. How many grams of indium do you need? (5) 3 Ba + Al20,-, 3 Bad) + 2 Al Barium metal reacts with aluminum oxide to form barium oxide and aluminum metal as above. Suppose 200.0g of barium and 1000 g of aluminum oxide are used. (a) Which is the limiting reactant? (Hint: Calculate the number of moles of Ba and Al:0 (b) What is the theoretical yield of aluminum (in grams)y? (6) Calcium reacts with iodine to form calcium iodide: Ca+1: â Cal: Suppose you use 3,00 g of calcium and 12.0 g of iodine. Which one is the limiting reagent? How many grams of calcium iodide can you theoretically get? (7) Vanadium reacts with iodine to form vanadium (III) iodide: Suppose you heat 27.0 g of vanadium with an excess of iodine and you ohtained 172 g of vanadiam (I11) iodide. What is the percentage yield of the reaction? (8) Lanthanum burns in oxygen to form lanthanum oxide according to the following equation: Suppose you react 2.00 g of lanthanum with oxygen and you obeain 2.17 g of lanthanum oxide. What is the percentage yield of the reaction?
