There are 6 types of reactions, and 3 of them have already been covered (synthesis, decomposition, and single replacent). Now, we will look at double replacement, combustion, and neutralization.
Reaction between two ionic combounds. (AB+CD------> AD+CB)
All ions bond with other ions that they have nota been with yet; then balance the equation.
Eg: 2LiCl + SrO -----> Li2O + SrCl2
Eg: RbF + CsBr-----> RbBr + CsF
A combustion reaction between organic molecules and an oxidant. The product will always contain water (H2O and Carbon Dioxide.
Eg: CH4 + 2O2 ----> CO2+ H2O
A neutralization reaction is when an acid reacts with a base to form a salt. The product will always include H2O. Acids have H in the front, and bases have OH at the end.
Eg: HCl + NaOH---> NaCl+ H2O
* Look at the solubility sheet to see which compounds are soluble or not soluble.
Here is a link to rules of solubility tutorial!
If all the compounds are aq, there will be no reaction!

Ions that are not useful in the reaction are reduced out of the equation.
