  2. Br2 + Cl2 2 BrCl • Page 311 #4a. How many moles of BrCl form when 2.74 mol Cl2 react with excess Br2?

  3. Br2 + Cl2 2 BrCl • Page 311 #4b. How many grams of BrCl form when 239.7 g Cl2 react with excess Br2?

  4. Br2 + Cl2 2 BrCl • Page 311 #4c. How many grams of Br2 are needed to react with 4.53 x 1025 molecules Cl2?

  5. 2C2H2(g) + 5O2(g)  4CO2(g) + 2H2O(g) • Page 311 #5a. If 15.9 L C2H2 react at STP (Standard Temperature and Pressure), how many moles of CO2 are produced? (Hint: At STP, 1 mole = 22.41 L for any gas.)

  6. 2C2H2(g) + 5O2(g)  4CO2(g) + 2H2O(g) • Page 311 #5b. How many milliliters of CO2 (density 1.977 g/L) can be made when 59.3 mL O2 (density = 1.429g/L) react?
