  1. Level ONE (I) • Write the correct formula for the following compounds: A. TriphosphorusNonaselenide B. Aluminum bromide C. Cobalt (VI) Oxide

  2. Level ONE (II) • Predict and Balance the following chemical equations: A. Vanadium (VI) phosphate + Potassium sulfide  B. Lithium + Mercury (III) silicate 

  3. Level TWO (I) • Cesium chlorate decomposes to form cesium chloride and oxygen gas. How many moles of oxygen can be produced by decomposing 10 moles of Cesium chlorate?

  4. Level TWO (II) • When nitrogen gas reacts with hydrogen gas, ammonia is produced. If 15 moles of ammonia were produced, how many moles of nitrogen gas would be required?

  5. Level THREE (I) • What mass of carbon monoxide must react with oxygen to produce 5g of carbon dioxide?

  6. Level THREE (II) • How many molecules of sugar (C6H12O6) are required to produce 1.82L of carbon dioxide gas at STP from the reaction described by the following equation: C6H12O6 2C2H6O + 2CO2

  7. Level THREE (III) • How many liters of oxygen are necessary for the combustion of 500 g of propane gas (C3H8)?

  8. Level THREE (IV) • Determine the mass of sodium fluoride when bubbling fluorine reacts with 12g of Sodium chloride.

  9. Level FOUR (I) • If you were given 10 grams of ammonium nitrate and 20 grams of rubidium phosphate, 1. determine the limiting reagent and excess reagent2. What is the maximum amount of each product formed? (mol or mass) • 3. How much of your excess is used up? Left over? (grams)

  10. Level FOUR (II) • If you were given 12 grams of calcium chloride and 18 grams of francium permanganate, 1. determine the limiting reagent and excess reagent2. What is the maximum amount of each product formed? (mol or mass) 3. How much of your excess is used up? Left over? (grams)
