Combustion
How many products are in decomposition?
Two or more
How do you know if a reactant is a combustion reaction?
If it is a compound plus a oxygen
What is the difference between single and double replacements?
Single replacement is when the single element is swapped out with one of the elements in the compound and double replacement is when an element from each compound is exchanged
