***Remember to balance!!!*** This stuff again? We covered that ages ago. I KNOW WE DID! BUT there is a little more to it this time. First of all lets go over the 6 types of reactions. Sythesis, Decomposition, Single Replacement, Double replacement, Combustion and Neutralization Synthesis This type of reaction combines 2 or more rectants to form a product A + B ---> C 2Fe + 1O2 ----> 2FeO Decomposition This reaction breaks down a reactant into two or more products. A ----> B + C 2FeO ---> 2Fe + 1O2 Singple Replacement This reactions replaces the ion in an ionic compound.. Metal elements replace positive ions and Non-metal elements replace negative ions. For Metals For Non-Metals A + BC ----> B + AC A+BC ---> C +BA Ba + Ca(NO3)2 ---> Ca + Ba(NO3)2 Now for the extra thing I was talking about. We are going to add something to spice up our equations. Activity Series The activity series is a chart which tells how reactive a metal or a a non-metal is. The element higher up on the series replaces the ion below it on the table. Here is what it looks like *Note* There are more metals and non-metals that could be placed on this chart. Reactive? E.G. 2Li + MgCl2 ----> 2LiCl + Mg YES For more info please visit these following websites: http://chemistry.about.com/od/chartstables/a/Activity-Series-Of-Metals.htm http://www.chemistryexplained.com/Ce-Co/Chemical-Reactions.html
