Single Replacement

What do we look at to determine if an element is strong enough to replace another element in a single replacement reaction?

• Solubility Rules 
• Ionic Charges
• It must be insoluble!
• Activity Series

Define a single replacement reaction.

• A compound reacts with another compound to produce two new compounds.
• A hydrocarbon reacts with water to produce carbon dioxide and water. 
• An element reacts with a compound and produces a new compound if the single element is higher in reactivity.
• An element reacts with another element to produce a compound.
