1. HMSA: Agenda Work on Computer Simulation
Today’s WS: Types of Reactions, Stoichiometry Review

2. For Balanced Chemical Equations:
The coefficients represent the relative number of moles of substance that is being reacted or produced.
We can use the mole ratios (from the coefficients of the balanced equation) and dimensional analysis to solve stoichiometry problems involving chemical reactions.

3. 1 N2 + 3 H2 ---> 2 NH3 10 moles NH3 1 mole N2 2 moles NH3

10 moles NH3
1 mole N2
2 moles NH3

4. 1 N2 + 3 H2 ---> 2 NH3

5. 1 N2 + 3 H2 ---> 2 NH3 3 mole H2 1 mole H2 2.02 grams H2
d. If moles of NH3 were produced, how many grams of H2 are required?
