Reaction Type Facts
What are products?
The elements/compounds created during a chemical reaction
AB ---> A + B
Decomposition
What is the number before a molecule called? (ex: the "4" in 4NaCl)
The coefficient
What are reactants?
The atoms present at the start of the reaction
What is on the right side of the equation arrow?
Products
A + B ---> AB
Synthesis
___Na + ___Cl2 -----> ____NaCl
2Na + Cl2 -----> 2NaCl
Write a Decomposition Reaction using "AB" as your starting molecule
AB ---> A + B
What type of reaction combines two atoms to make one product?
Synthesis
AB + CD ---> AD + BC
Double Replacement
Why do we need to balance equations?
All atoms must be accounted for: you cannot create or destroy matter
Balance this:
___H2 + ____O2 -----> ____H2O
2H2 + O2 -----> 2H2O
True or false: a decomposition reaction will have two or more products
True
AB + C ---> AC + B
Single Replacement
Balance this:
___H2O2 -----> ____H2O + ____O2
2H2O2 -----> 2H2O + O2
