There are many chemical reactions that take place between chemicals and their reactants, most of them occuring inside our body without us realizing it. These reactions include synthesis, decomposition, single-replacement, double replacement, and combustion.
Synthesis is a chemical reaction in which it is purposely made to react with another chemical or chemicals. it is also physically or chemically manipulated. This usually means that the reaction is reproducible and reliable.
Another type of reaction is known as chemical decomposition. This involves the seperation of chemical compounds, and, in turn, breaking the compound down to simpler elements or compounds. These type of reactions are usually undesired.
Single-replacement reactions are yet another type of reaction. This type of reaction is also known as an oxidation-reduction chemical reaction. This is when an element or ion moves from one compund to another. the elements usually replace each other in their respective compounds.
Another similar reaction to the single- replacement reaction is called the double-replacement reaction. It is also called the metathesis reaction. Instead of exchanging single elements, like the single-replacement reaction, this involves the exchange of bonds resulting in chemical species with similar bonding affiliations.
The last form of reaction is called combustion. This, no doubt, involves heat. It is a series of exothermic reactions with fuel and its oxidant accompanied by heat. This heat usually causes glowing or flames. Many fuels often include hydrocarbons.
These reactions provide the basis of what created life and helped to create the world we know today.

COMBUSTION
A combustion reaction takes place when a fuel and an oxidant react, producing heat or heat and light. The most recognizable form of combustion reaction is flame, with explosions being an even faster form of combustion reaction. A combustion can happen at a wide range of speeds, and can occur in many different environments, but the majority of combustions we know and recognize happen in a fairly limited spectrum.
DECOMPOSITION
A decomposition reaction is a type of chemical reaction in which a substance degrades into two or more basic components. It is a process in direct contrast to that of chemical synthesis, which involves molecular bonding so that two or more components may join to form a single chemical compound. The decomposition reaction often requires exposure to a catalyst, such as a heat source or solvent.
SYNTHESIS
A synthesis reaction or direct combination reaction is one of the most common types of chemical reactions. In a synthesis reaction two or more chemical species combine to form a more complex product.
A + B → AB
SINGLE-REPLACEMENT
A single replacement reaction, sometimes called a single displacement reaction, is a chemical reaction where one element replaces another element in a compound to increase stability. An example of a single replacement reaction that takes place in real life is when oxidation forms rust on cars.
DOUBLE-REPLACEMENT
double replacement reaction - a chemical reaction between two compounds where the positive ion of one compound is exchanged with the positive ion of another compound.

The making of the "Halloween Reaction"
Austin performing on stage: 
When Austin performed this demonstration on stage, i was surprised too. Even though we were already told of what was going to happen i was amazed by how the colors changed so quick. I felt the the audience like it because all the excitement i heard from them. Austin looked great up there because he was constantly smiling and he looked like he totally knew what he was doing, like it has already been practiced on a few times. when the colors changed you could see his face light up, before when he was pouring in the chemicals, he look like he wasn't sure of what was going to happen; he was probably thinking the same as me when i saw it, i didn't know that the demonstration was actually going to work because we haven't experimented it before the show, but when the color changed i was relieved, happy that it did what it was supposed to do. I think that this was a great experience to be able to show how fun science is to other peers. I don't know how the others felt about the show, but I felt really good about it.
