Application Examples:
1. Reactivity Series
The alkali metals are never found in an uncombined form in nature. Using the activity series, explain
this observation.
2. Types of Reactions
Both single and double displacement reactions result in removal of an ion from a solution. Which type
of displacement reaction would you use if the ion were of a valuable element, such as gold?
3. Law of Conservation of Mass
Why is it important for manufacturers of products to understand the law of conservation of mass?
4. Chemical Formulas
What is the correct ratio of aluminum ions to carbonate ions in the compound aluminum carbonate?
(Ratio 1:1)
