In a small group write up a clear, step-by-step guide to solving stoichiometry problems. Type this on a computer using everyone’s input.
Think up an example and give it after your written guide.
At the end of your document, answer this question: “What is the most important step and why?”
Do the two problems below after you have your teacher’s approval of your procedure. Everyone should make an effort to be in control of their own learning. Do not let someone else do the work while you watch and copy!
CaC2(s) + 2H2O(l) → C2H2(g) + Ca(OH)2(s)
2C2H2(g) + 5O2(g) → + 4CO2(g) + 2H2O(g)
If you have 3.0 g of calcium carbide (CaC2) how many grams of acetylene (C2H2) can you make?
If you have 5.4 g of acetylene then how many grams of carbon dioxide form when it burns?
Now that you have completed a few problems discuss any revisions or changes that need to be made to your step-by-step guide. Make them and finalize your draft.
Print a copy of your guide for each member of your group.
