You get to know the major kinds of chemical reactions including polymerization, hydrolysis, combustion, replacements, and redox. Experiment with some electrochemical reactions as well.
After completing this tutorial, you will be able to complete the following:
What is a single-replacement reaction?
~ A single-replacement reaction occurs when one element replaces another element in a compound. In single-replacement reactions, only one element, called a reactant, replaces another element in a compound, which forms the other reactant. One reactant in a single- replacement reaction must be an element, while the other must be a compound. For example, when an aluminum plate is dipped into a copper chloride solution, the copper ions in the solution are replaced by aluminum atoms.
What are the different types of single-replacement reactions?
~ One type of single-replacement reaction occurs when a metal atom, the reactant, replaces another metal atom in a solution. A second type of single-replacement reaction occurs when a nonmetal atom reactant replaces another nonmetal atom in a solution. In the third type of single-replacement reaction, a metal atom replaces one of the hydrogen atoms in a water molecule. The fourth type of single-replacement reaction occurs when an active metal atom replaces a hydrogen atom in a diluted sulfuric acid hydrochloric acid solution.
In a single-replacement reaction, a reaction only takes place if a more reactive metal replaces a less reactive one. In a single-replacement reaction, would manganese replace tin? Why or why not?
~ In a single-replacement reaction, manganese would replace tin because manganese is more reactive than tin.
Like metals, nonmetals have different reaction levels. In a single replacement reaction, would iodine replace bromine?
~ No, iodine would not replace bromine in a single-replacement reaction because iodine is less reactive than bromine.
