Experiment 1: Steel wool

 

 

 

 

 

 

This is an example of a synthesis reaction. During this experiment, the steel wool and the oxygen in the surrounding area combined to create one whole compound. This resulted in a change of color of the steel wool furthermore the steel wood become more brittle to the touch.

 

Experiment 2: Butane Lighter

 

 

 

 

 

 

 

This is an example of a combustion reaction. This experiment is an example of a combustion reaction because the hydrocarbon of the butane lighter mixed with the air (oxygen) around and became water and hydrogen. This was observed in the ripples in the area surrounding the flames, as the heat distorted the air

 

Experiment 3: Hydrogen Peroxide

 

 

 

 

 

 

This is an example of a decomposition reaction. In this reaction, the oxygen is combined with the hydrogen peroxide and caused it to transform from a deeper brown into a lighter orange, it became very hot and bubbled over the glass tube turning it into a gas.

 

Experiment 4: Copper Wire

 

 

 

 

 

 

This is an example of a single replacement reaction. In this experiment, the copper from the wire replaced the silver in the solution, this caused the copper metal to begin to disintegrate and change colors from a shiny copper to a matte green and brownish color (similar to army green and moss), pieces of the wire began to flake off. The pieces that came off resembled small flakes of moss.

 

Experiment 5: Potassium Iodide + Lead Nitrate

 

 

 

 

 

 

 

This is an example of a double replacement reaction. In this reaction, the potassium and lead switched places, this resulted in the previously clear liquid with a consistency similar to water turning a bright vibrant yellow that appeared to be the consistency of paint.

 

 

Experiment 6: Sodium Hydroxide + Sulphuric Acid

 

 

 

 

 

 

 

This is an example of an acid-base neutralization reaction. This experiment demonstrated this type of reaction because the mixture of the acid and the base in the first well, created a salt and water. This turned the litmus red and blue (this was a change from the other examples). This happened because both the salt and water are considered to be neutral, with slight variation.
