Single Replacement

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.
