Reaction Types of Doom!!!

Ahh we're finally into my favorite part of chemistry!  I love molecules and chemical equations.  They're so much fun to balance.  I loved balancing equations in intro to chemistry but I really need a refresher on how to do it.  I took the class freshman year and, alas, I have forgotten how to do it.  I just like it.

Learning the reaction types will do for now!

Synthesis:                    A+B→AB
Decomposition:           AB→A+B
Single Replacement:    A+BC→B+AC
Double Replacement:  AB+CD→CB+AD
Combustion:               Fuel+O2→H2O+CO2

So reaction types are easy to remember and are quite obvious.  We did a series of little labs, seven in total, where we mixed a couple of things together or added heat to something and observed the reaction.  Nikki and I wrote down the equation for what happened and what we saw happening and labelled the reaction as one of the types of reactions.  I'm not going to write up all the labs because there were seven of them and I don't feel like writing them up.  Besides that I probably got them all wrong.  It's a lot different to name a reaction or equation from what you see verses what you can do on paper with other reactions.  I might not be able to perfectly translate my skills with this stuff to real world application but I still have fun doing it on worksheets.
