Date Assigned: _________________Date Due:_________________Basic StoichiometryHow do chemists calculate quantities of reactants and products in chemical reactions?Why?One of the most important tasks for chemists is to be able predict not only the formulasof reactants and products in chemical reactions, but also the quantities of reactant andproducts. For example, if a chemist for a pharmaceutical company needs to produce aspecific amount of a medication from a chemical reaction, they are going to need toknow how much of the reactants to start with. Chemists use the process ofstoichiometry to solve these kinds of problems.Model 12A + 3B5C + 4DMolar Ratio2 mol A produces 5 mol C3 mol B produces 4 mol D2 mol A reacts with 3 mol B1.What do the coefficients of a balanced equation represent?2.Write three other molar ratios from the equation in Model 1.3.Now for the three molar ratios you wrote in question #2, write each molar ratio as aconversion factor.(ex: 2 mol A = 5 mol C)4.Write a definition for the termmolar ratio5.If 6 mol A are reacted, how many mol D are formed? Explain as a group how youcalculated this answer and show your work using dimensional analysis..
Model 22A + 3B5C + 4DIf 3 mol A react, how many mol C are produced?3 mol Ax5 mol C=7.5 mol C2 mol A6.If 21.0 mol A are reacted, how many mol C are produced? Using dimensionalanalysis, show how you calculated your answer.7.If 21.0 mol B are reacted, how many mol A must have been consumed?8.If 0.013 mol D are produced, how many mol C must also be produced?9.Discuss as a group and definestoichiometryin your own terms.
