In this chemical reaction, they combined two different substances. I am not sure what they are. First, the reaction was red. Then it turned yellow and started to rise and bubble. After that, it turned white and covered the cylinder. The substance bubbled up and turned into a gas like substance.

1. Single Displacement is also known as Single Replacement reaction. This elxplains when one element moves from one compound to another. Double Displacement is similar to Single Displacement except that instead of one element just moving to another compound, the element switches place with another element in the compound.
Synthesis is a reaction that combines molecules to make a compounds.
Decompesition is a reaction when compunds break up into individual molecules.
2. Precipiation is the term for a solid in a solution during chemical reaction.

The video is an example of single replacement reactions. The first in which copper in a strip of metal will replace silver in a silver nitrate compound. The second example is zinc replacing hydrogen in hydrochloric acid. The third part of thevideo is an example of double replacement reaction which sodium leaves sodium phosphate to trade places with lead in lead 2 nitrate. The next is an example of decomposition of a compound that seperates hydrogen and oxygen. The final example is and example of combustion.

Single Displacement:
Double Displacement: When each compound changes elements with the other compound. When an ion is formed and this ion takes the place of ion in the compound.
Synthesis: When two elements added together form a compound.
Decomposition: When two, or more than two, elements are formed out of a compound.
2. A Precipitate is when you separate a compound that is solid.
3. Video Link:

1. Single Displacement: In this type of reaction, a neutral element becomes an ion as it replaces another ion in a compound.
Double Displacement: the compounds in this type of reaction exchange partners.
Synthesis: A synthesis reaction involves two or more substances combining to make a more complex substance. The reactants may be elements or compounds, and the product will always be a compound.
Decomposition: In a decomposition reaction, one substance is broken down into two or more, simpler substances.
2.Precipitate: Precipitation is the formation of a solid in a solution during a chemical reaction. When the reaction occurs, the solid formed is called the precipitate, and the liquid remaining above the solid is called the supernate.
3.http://www.youtube.com/watch?v=Mx5JJWI2aaw&feature=related
this is a synthesis chemical reaction because the
sodium combines with the chlorine to make a
new substance- sodium chloride (NaCl) also
known as salt.

1. Single Displacement: In a “Single Displacement” reaction two reactants yield two products. In a “Single Displacement” reaction a single element takes the place of another element as a form of a compound.
Double Displacement: In a “Double Displacement” reaction, parts of two compounds exchange places. In this type of chemical reaction, two compounds yield two compounds.
Synthesis: In a “Synthesis” reaction two or more reactants yield one product. The two (or more) reactants (in a Synthesis reaction) are simple substances and their products result in compounds.
Decomposition: In a “Decomposition” reaction one reactant yields two or more products. In a “Decomposition” reaction a compound breaks down into smaller, simpler substances.
2. Precipitation in chemistry terms: The process of a solid substance being separated from a liquid due to chemical reactions.
3. http://www.youtube.com/watch?v=ul4xRy8hcsQ – In this video there are two experiments that take place. I will be explaining the first experiment. In the first experiment a “Single Displacement” reaction takes place. In this “Single Displacement” reaction, Copper takes the place of Silver Ions in a solution of Silver Nitrate. During the process of the chemical reaction, the water from the solution of Silver Nitrate turns from clear to light blue and silver starts to form on the metal strip of copper.

1. Single Displacement Reaction: This is also called "Single Replacement". In the single displacement, an element replaces another element in a compound.
Double Displacement Reaction: This is also called "Double Replacement", just like the single displacement. In this reaction, two compounds react and exchange positive and negative ions.
Synthesis Reaction: In a synthesis reaction, compounds or elements react to form more complex compounds.
Decomposition Reaction: In this reaction, a compound reacts to form elements or less complex molecules.
2. The definition of precipitate is to form an insoluble compound either by reacting two salts or by changing the temperature to affect the solubility of the compound. Also the name given to the solid that is formed as a result of a precipitation reaction.

1) Single displacement is where an element replaces or displaces another element from compound in a reaction. Double displacement is where parts of two compounds switch places to create to new compounds. During a synthesis reaction, two or more elements merge to create a compound or a more complex substance. A decomposition reaction is the opposite of a synthesis reaction, because it's where a compound or a complex substance breaks down in to elements.
2) A precipitate is the solid formed during the formation of a solid in a solution during a chemical reaction.

There were several different chemical reactions shown in this video, but I chose only to do the first one that is shown.
This chemical reaction starts with a silver nitrate and copper. When the copper is put into the silver nitrate the copper begins to get covered is silver particles. Slowly the silver nitrate begins to turn into copper nitrate. While the silver nitrate was clear the copper nitrate was blue, which was how I could tell that a chemical reaction had occurred. This is an example of a single displacement.

1) In a single displacement an uncombined element replaces another element that was already in a compound. A Double Displacement the elements in one compound mix with elements in another compound and form two new compounds. A Synthesis Reaction is where two simple elements combine together to form a more complex element. Decomposition is the opposite as Synthesis. Decomposition is where one complex substances yield into two simple substances.
2) A Precipitate is to form a compound by reacting two salts or changing the temperature. A Participate is the solid that is forming from reacting two chemicals and water. Participation is the process.
3) The chemical reaction is a single replacement, a thermite reaction which has a reducing metal and a metal oxide http://video.google.com/videosearch?q=single+replacement+reactions&emb=0&aq=f#

1) Synthesis
A synthesis reaction is when there is a combination of two or more substances and a compound results. An example of a synthesis reaction is as follows:
A + B --> AB
Decomposition
Decomposition is the opposite of synthesis. It is when a compound is broken down into simpler substances, usually through electrolysis. An example of decomposition is as follows:
AB --> A + B
Single Replacement Reactions
In a single replacement reaction, there is a rule that is always followed. A metal replaces a metal, or a nonmetal replaces a nonmetal. An example of a single replacement reaction is as follows:
A + BC --> AC + B
Double Replacement Reactions
In a double replacement reaction, this rule is always followed. A metal replaces a metal, and a nonmetal replaces a nonmetal. An example of a double replacement reaction is as follows:
AB + XY --> AY + XB

3) The first part shows sodium exploding violently in water. The sodium chunk starts to sizzle and when it is heated enough, the sodium explodes due to a chemical reaction. The second is showing potassium being dropped in green water. Due to a chemical reaction, the potassium reacts almost instantaneously and also the water changes color.

1)Single Replacement is when a chemical reaction turns into something else because one atom switched with the other. Double Replacement is when 2 atoms switch with 2 others. Synthesis is when something combines to make something else. Decomposition is when a chemical splits into something smaller like water splitting to hydrogen and oxygen.
2)Precipitate is the solid at the bottom of our experiments. It is when liquids combine and make a solid.

1. Single Displacement:
When an element moves out of a compound and go into another compound. Which easily say, one element is replaced by another a compound.
Ex) A + BC→ AC + B
Double Displacement:
This is totally opposite of Single Displacement. It is when two compounds switch places to form two new compounds.
Ex) AB + CD → AD + BC
Synthesis:
It is a reaction that two or more compounds combine to form a more compound.
Ex) A + B →AB
Decomposition:
Decomposition reaction is a compound breaks down into two or more compounds.
Ex) AB → A + B
2. Precipitate is formation of a solid in a solution during a chemical reaction

1. A "single displacement" is when one single uncombined elememt replaces another element in a compound. The element replaces a spot in the product side of the arrow. A single displacement mostly has 2 reactants yield to 2 products.
A "double displacement" is nearly the same as a single displacement. But the only thing different about this is that a parts f 2compounds replace to form 2 new ones. So instead of only one replaceing this is two parts replacing 2 others, to form 2 new compounds.
A "synthesis" reaction is when 2 or more simple substances(elements,compuonds) goin together to form a more complex substance.
It is likely that 2 or more reactants yeild into 1 product.
"Decomposition" is the opposite of synthesis. Decomposition is when one complex substance breaks down into more simpler elements, compounds, or substances.
Mostly it's one reactants yield into many other products.
2.A precipitate is when a solid that is not capable of being dissolved appears from a liquid solution.

1) A synthesis reaction involves two or more substances combining to make a more complex substance. A+B --> AB
A decomposition reaction is a reaction in which a single compound decomposes to two or more other substances. AB --> A + B
A single-replacement reaction is a reaction in which an element reacts with a compound and replaces another element in the compound.
A + BC --> AB + C
A double-replacement reaction is a reaction in which there is an exchange of positive ions between two compounds. AB + CD --> AD + CB
2) A precipitate is The emergence of the insoluble solid from solution is called precipitation. Precipitates can form when two soluble salts react in solution to form one or more insoluble products. The insoluble product separates from the liquid and is called a precipitate.

1.Single displacement is a type of reaction where one free element displaces another element to form a new compound and a different free elemenet. For example, single displacement occurs in
2Al (s) + Fe2O3 (s) → Al2O3 (s) + 2Fe (l).
Double displacement is a type of reaction when two ore more free elements displaces another element to form a new compound and a different free element. This is a reaction where double displacement takes place:
BaCl2 (aq) + H2SO4 (aq) → BaSO4 (s) + 2HCl (aq)
A synthesis reaction is when two or more simple substances combine to become a more complex substance.
Decomposition is a reaction where a complex substance breaks into simpler substances.

1.A synthesis reaction involves two or more substances combining to yeild a more complex substance. The reactants may be elements or compounds, and the product will always be a compound.
In a decomposition reaction, one substance is broken down into two or more, simpler substances. This type of reaction is the opposite of a synthesis reaction.
In a single replacement reaction, a single element replaces a place of another compound's element.
Double replacement reactions occur when one of each element in a different compound exchange with the other one.

1) Single displacement is also called a single replacement reaction. It is the process when an unbonded element replaces another element in a chemical compound/bonding.
Double displacement is also called a double replacement reaction. It is the process involving the exchange of bonds between the two reacting chemical species/elements. In other words, two elements in separate bonds "exchange partners," or interchange.
Synthesis is when two or more substances/elements combine to form a single, more complex substance/compound.
Decomposition is when one substance/compound is broken down into two or more simpler substances. It can be thought of as the opposite of synthesis.
