acid-base ractions

THESE REACTIONS FORM WATER!!!!!!!!!!!!!!! Just in case you were wondering. An acid-base reaction consists of an acid and a base. Which produce water as the driving force behind the reaction. Also there is a high likelihood of production of salts. These reactions are most easily figured out by looking at the type of acid/base used in the reaction. This will tell you some important information on the products of the reaction. One of the big factors is if the base/acid is strong or weak. In any case if the reactants are strong then they will "Disappear"from the reaction. If a reactant is weak then it will also appear in the products.

Double-replacement reactions

Double replacement reactions consist of two separate compounds trading anions with each other. Now I know its not that simple. There is a driving force of the production of a solid in these reactions. The main concern when figuring out these reactions is telling if a solid actually forms. To know this we have to memorize the solubility rules. These rule tell whether or not the compound that forms is aqueous or not.

Redox reactions Part 2

The third and fourth chemical reactions are Single replacement and Combustion reactions. Single replacement reactions are when an external metal and a metal anion switch places to form a compound and a single metal as products. For example, A+BC -> AC+B. The driving force, because it is a redox reaction, is the transfer of electrons. A Combustion reaction is when a compound/element reacts with oxygen to form water and carbon dioxide. For example, (compound) + O2 -> H2O + CO2. If the combustion reaction is using a hydrocarbon (compound with hydrogen carbon and sometimes oxygen), then to balance it you should use the CHO method. Which consists of starting by balancing Carbon then Hydrogen and then Oxygen.

Redox Reactions

Decomposition and synthesis reactions. The Driving force of a redox reaction is the transfer of electrons. Two different ways the electrons can be transferred are decomposition and synthesis reactions. Decomposition is when a single compound is split apart in to separate products. The second way is a synthesis reaction. Opposite from a decomposition, a synthesis reaction is when two compounds/atoms form together to make a single compounded product. Both of these are redox reactions.

Chemical reactions lab

Today we did a lab to test how certain elements would react with certain liquids. The elements were Lead, copper, calcium, magnesium, Zinc, and Tin. We had to place one of each of the metals into a well plate and then put a couple drops of water on each metal. We also did this with Hydrochloric acid, copper sulfate, and silver nitrate. Each liquid was put onto a fresh piece of metal that had not been reacted with. The most reacted liquid was Silver Nitrate which reacted with all but one metal. The results were quite interesting in that multiple different compounds of varying color formed.
