Chemical Reaction

This is another ace project which I have done. This time, I did it using prezi. This is the link : http://prezi.com/ptncyyzgtf84/chemical-reaction/.

Chemical reaction :

• Reaction of two or more elements/compound together
• Formation of a chemical bond between atoms
• Formation of a chemical compound

Six types of reaction :

• Combustion
  
• Synthesis
• Decomposition
• Single displacement
• Double displacement
• Acid-base

I will be focusing on combustion, synthesis and also decomposition.

Combustion :

• The combination of water and other compounds/elements to form water and carbon dioxide
• For example : Burning of wood

Synthesis :

• Two or more compounds/elements form a more complex compound
• For example : Mixture of iron and sulfur to form iron ( ll ) sulfide

Decomposition :

• The seperation of a complex compound into simpler and smaller substances
• Opposite of synthesis reaction
• For example : Use of electrical current to seperate water into hydrogen and oxygen

Diet coke and Menthos

Soda drinks have carbon dioxide gas in them, and this is what makes it bubbly. this carbon dioxide gas stays suspended in the liquid of bottles of soda, until you open and pour it out. mentos consists of sugar and some other things. one of them is called gum arabic, and it makes the mentos chewy.
As mentioned in the video, there are tiny pits on the mentos which produce carbon dioxide gas. this gas is released, along with the extra pressure which cause the carbon dioxide in the soda drinks to break apart faster by the gum arabic when it is finally released, this pressured-gas in soda drinks thrust out of the bottle, bringing the contents along with it.

Now let us watch a video on diet coke and menthos.
