| The picture shows Mr. Oil and Mr. Vinegar fighting and no one knows the reason. So, the kind-hearted Mr. Emulsifier (yeast) tries to stop them. And BAM! A chemical reaction had just occurred. *laughs out loud* The end. |
HELLO THERE FRIENDS! There are five types of chemical reaction and here they are:
1) Combustion: A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide. These reactions are exothermic, meaning they produce heat. An example of this kind of reaction is the burning of napthalene:
C10H8 + 12 O2 ---> 10 CO2 + 4 H2O
 |
| Familiar isn't it? Yes, those our candies. Blah! I'm just kidding, those are NAPTHALENE BALLS. Look inside your drawers, you can see one! :D |
2) Decomposition: A decomposition reaction is the opposite of a synthesis reaction - a complex molecule breaks down to make simpler ones. These reactions come in the general form:
AB ---> A + B
One example of a decomposition reaction is the electrolysis of water to make oxygen and hydrogen gas:
2 H2O ---> 2 H2 + O2
3) Single displacement: This is when one element trades places with another element in a compound. These reactions come in the general form of:
A + BC ---> AC + B
Example:
When magnesium replaces hydrogen in water to make magnesium hydroxide and hydrogen gas:
Mg + 2 H2O ---> Mg(OH)2 + H2
4) Double displacement: This is when the anions and cations of two different molecules switch places, forming two entirely different compounds. These reactions are in the general form:
AB + CD ---> AD + CB
Example:
Reaction of lead (II) nitrate with potassium iodide to form lead (II) iodide and potassium nitrate:
Pb(NO3)2 + 2 KI ---> PbI2 + 2 KNO3
5) Synthesis or Combination: A synthesis/combination reaction is when two or more simple compounds combine to form a more complicated one. These reactions come in the general form of:
A + B ---> AB
Different kinds of Combination/Synthesis Reaction
1) Combination of metals and oxygen to form metallic oxide. Metal oxides, sometimes called basic oxides, are usually ionic compounds.
2) Molecular compounds, this is created when nonmetals react with oxygen or another nonmetals.
3) Salts, combination of metals and nonmetals.
4) Compounds also undergo combination reactions. Metal oxides react with water to form metallic hydroxides called bases.
5) Nonmetal oxides or acidic oxides react with water to form acids. Example of this reaction is the formation of acid rain.
So, this is all we have and all we can give to you for now dudes! When there's an update we'll give you the update, no more and no less also, still fresh! So long dear ones! Ciao! :D
