Presentation Transcript
1. DRILL ON STOICHIOMETRY

2. This is one of the reactions in fireworks……2KClO3 → 2KCl + 3O2If 1.40 moles of KClO3 decompose, how many moles of O2 are formed?

3. 2KClO3 → 2KCl + 3O2If enough KClO3 decomposes to form 1.00 grams of O2, how many grams of KCl are formed?

4. You are a NASA engineer. Your job is to design the CO2 filters for the Space Program….

5. The CO2 is pumped through the filters, and the following reaction occurs:2LiOH + CO2 → Li2CO3 + H2O Make-shift carbon dioxide filter on Apollo 13

6. 2LiOH + CO2 → Li2CO3 + H2OIf you react 1.00 g LiOH, how many grams of CO2 will be consumed?

7. If only 0.800 grams of CO2 are comsumed, what is your percent yield?
