Solving Stoichiometry Problems
Solving Stoichiometry Problems
In this lesson, students explore three combustion reactions to develop skills necessary to solve stoichiometric problems.
- Students will write mole ratios from balanced chemical equations.
- Students will use mole-to-mass conversion to determine mass of reactants and products given the number of moles.
- Students will calculate the number of moles and the mass of a reactant or product when given the number of moles or the mass of another reactant or product using the balanced chemical equations.
- Students will list the steps used in solving stoichiometric problems.
- mole
- mole ratio
- mole-to-mass conversion
- mass-to-mole conversion
- molar mass
- combustion
- reactant
- product
This lesson involves students using a simulation of three combustion reactions to develop skills necessary to solve stoichiometric problems. A guided lesson video (optional) is also available for this activity. The video is targeted at students and designed to help guide them through the interactive exploration and the concepts covered within. (It may also be helpful for teachers who may be using the activity for the first time.)
- Students will use the combustion of methane to analyze mole ratios in chemical reactions.
- Students will the use the combustion of propane to analyze mole to mass conversion.
- Finally, students will use the combustion of propane to analyze mass to mole conversion.
As a result, students will:
- Reinforce the skills of balancing chemical equations
- Develop a method of solving stoichiometry problems
