Points to Consider
- In an earlier section, we discussed the origins of the chemical recipe for gunpowder, one of the earliest
chemical formulas to be described. The recipe for gun powder is 75 percent potassium nitrate, 15 percent
charcoal, and 10 percent sulfur. How might one measure out these amounts in a predictable and reliable way? - So far, we have discussed the characteristics of a variety of reactions. However, we have spent little time
discussing how we might measure and calculate amounts of reactants and products. The steel wool reaction is
as follows: 4Fe(s)+3O 2 (g)→2Fe 2 O 3 (s). How might you measure the amounts of each reactant used and the
product that forms? - In the chemical reactions that we have already studied, we have assumed that all reactants are transformed
into products (the reaction "goes to completion"). Are there reactions that do not go to completion? How do
you know whether you will have reactants left over? - What are some factors that control whether or not a chemical reaction takes place?
