• One chemical species breaks down to simpler elements/compounds

What occurs during a double replacement reaction?

• A hydrocarbon burns in oxygen

• An uncombined element replaces a less reactive element in a compound

• One chemical species breaks down to simpler elements/compounds

• Involves two ionic compounds that trade cations, creating two new compounds

What is produced in a combustion reaction?

• A more complex product from two or more elements/compounds

• Two new compounds from the trading of cations between two ionic compounds

• Carbon dioxide and water from a hydrocarbon burning in oxygen

• A less reactive element in a compound is replaced by an uncombined element
