Answer:Not sure what exactly you are asking but here are the 5 types of reactions
Step-by-step explanation:
1) synthesis(combination, or composition old name) You add all reactants together to form 1 compound
A+ B--> AB
2) decompostion- Start with one reactant and it breaks down to 2 or more products
ABC--> AB + C
3) single replacement or sometimes called single displacement
You have one single element on both the reactant and product side
AB + C --> CB + A (positive charges trade places)
( this one is tricky because somtimes the element is a negative charge and if it is negative than it looks like this)
AB + C --> AC + B (negative charges trade places)
4) double replacement or double displacement
start with 2 compounds and produce 2 new compounds. I tell my students that the positive charges trade places
AB + CD ---> AD + CB
5) Complete combustions
hydrocarbon + oxygen --> Carbon dioxide + water
CH4 + O2--> CO2 + H20
to balnace it
CH4 + 2O2--> CO2 + 2 H2O
