Problem 13Balance the Equation • What mass of H2SO4 is produced from the reaction of 6.58 grams of SO3 and 1.64 grams of H2O????? SO3 + H2O H2SO4 H2SO4+SO3 H2O
Correct! SO3 + H2O H2SO4 1 Sulfur, 2 Hydrogen, 4 oxygen = 2 Hydrogen, 1 Sulfur, 4 Oxygen
Step 1 of Equation 1 6.58 g SO3 x __1 mol__ 80.86 g SO3 6.58 g SO3 x ___65 mols__ ` 81.34 g SO3 6.58 g SO3 x ____1 mol___ 101.25 g SO3
Correct! Good Job Keep Up The Good Work
Step 2 of Equation 1 1 mol x 265.17 g H2SO4 1 mol 2 mols 1 molx 98.08 g H2SO4 1 mol 1 mol 1 molx 121.55 g H2SO4 1 mol 1 mol
Excellent! Congratulations! From now on… If you get an answer correct, you will be forwarded to the next question
Step 3 of Equation 1 (6.58 + 98.08) (80.07) = 8.01 g H2SO4 (6.58 x 98.08) (80.06) = 8.06 g H2SO4 (7.0 x 97.99) (80.06) = 2.25 g H2SO4
Equation 2 of Problem 13 Repeated Question What mass of H2SO4 is produced from the reaction of 6.58 g of SO3 and 1.64 g of H2O?
Step 1 of Equation 2 1.64 g H2O x 1 mol 18.02 g H2O 1.64 g H2O x 1 mol 21.71 g H2O 1.64 g H2O x 1 mol 19.65 g H2O
Step 2 of Equation 2 1 mol x 145.23 g H2SO4 1 mol 1 mol x 98.08 g H2SO4 2 mols 1 mol x 98.08 g H2SO4 1 mol
Step 3 of Equation 2 • 8.9 g H2O • 9.7 g H2O • 4.2 g H2O
The Final Question • Which compound is the limiting factor??? • SO3 • H2SO4
