**Stoichiometry!**Paige Powell Period 8; April 2011 Mr. Kirk Click to start!**Your question is…..**How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? What now?! Set up the equation Solve the problem Give up**WRONG!!!**Why?: You haven’t even set up the equation yet! (hint hint) Click here to go back and try again!**What makes you think you can do that?!**Go to study tables… Smh Click here to start over!**Great Job .. And how would you do that?!**How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? SO + H O H SO 2SO + 2H O 2H SO 2 2 2 3 2 2 2 3 SO + H O H SO 3 2 2 3**You really know your chemicals! What now?**How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? 128g H SO Balance the equation 2 3 1 128g SO 2 1**WRONG!!!**Why?: You have the wrong chemicals! (check your periodic table) Click here to go back and try again!**WRONG!!!**Why?: The equation is already balanced! (use the laundry method to check) Click here to go back and try again!**x**1 mol SO 64.1g SO 1 mol SO 2 2 2 64.1g SO 1 mol SO 65g SO 2 2 2 128g SO 128g SO 128g SO 2 2 2 1 1 1 Great job! What’s the next step? How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? x x**WRONG!!!**Why?: Make sure you add up the chemicals correctly. (check the periodic table) Click here to go back and try again!**WRONG!!!**Why?: During gfm you need to cancel outgrams! Click here to go back and try again!**x**x x 1 mol SO 1 mol SO 1 mol SO 2 2 2 64.1 g SO 64.1g SO 64.1 g SO 2 2 2 128g SO 128g SO 128g SO 2 2 2 1 1 1 Great job! What’s the next step? How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? 1 mol SO__ 2 mol H SO 1 mol H SO x 2 3 2 3 1 mol SO 1 mol SO 1 mol H SO 2 3 2 2 x 2 x**WRONG!!!**Why?: In the balanced equation, there is only one mole of Sulfurous Acid, not two! Click here to go back and try again!**WRONG!!!**Why?: To cancel out the Sulfur Dioxide, it has to be placed in the denominator! Click here to go back and try again!**x**1 mol Super! What should we do next? How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? x 1 mol g H SO H SO H SO 2 3 2 3 2 3**WRONG!!!**Why?: You aren’t supposed to divide… I don’t even know what you’re thinking right now! For THAT kind of mistake, I’m going to have to make you START OVER!**WRONG!!!**Why?: To end up with grams at the end of your equation, it needs to be in the numerator in your last section of the problem! Click here to go back and try again!**Alright, so how many grams would that be?**How much sulfurous acid can be produce when 128g or sulfur dioxide combines with water? 82 g 82.1 g 83 g**WRONG!!!**Why?: Make sure you add up the chemicals correctly, using correct sig figs. (check the periodic table) Click here to go back and try again!**Okay smarty pants, what’s the final answer?**x 1 mol x 1 mol SO 2 64.1 g SO 2 128g SO 2 1 1 mol H SO 164 g H2SO3 x 2 3 1 mol SO 2 165 g H2SO3 164 g SO2 82.1gH SO 2 3**WRONG!!!**Why?: Make sure you’re multiplying correctly, and using the correct amount of sig figs! Click here to go back and try again!**WRONG!!!**Why?: You don’t even have the right ending chemical! Click here to go back and try again!
