8.962 Consider the unbalanced chemical equation Na+Cl2 -NaCl 1.Balance the equation. 3. To
produce 1 mole of NaCl from the reaction, how many grams of Na and Cl2 must you combine?
reaction you ran in part (c)? What is the percent yield? 4. What is the theoretical yield in grams
of NaCl from the 5. You carry out the reaction and recover 45.50 g of NaCl.
Solution
2Na + Cl2 ---------------> 2NaCl
2 mole of NaCl produced from 2 mole of Na
2molesof NaCl produced from 2*23g of Na
1 mole of NaCl produced from = 2*23*1/2Â Â = 23g of Na
2 mole of NaCl produced from 1 mole of Cl2
2mole fo NaCl produced from 71g of Cl2
1 mole of NaCl produced from = 71*1/2 = 35.5g of Cl2
