Oxygen and Reaction
Observations:

Part I: Reaction between iron and oxygen

Appearance of steel wool after 20 minutes From (relatively) shiny metal strips to not-so-shiny strips that are stained with dark, reddish-brown stuff.

Part II: Decomposition of hydrogen peroxide

Appearance of potato and hydrogen peroxide combination: Lots of white, foamy bubbles around the potato slices.

Day 2

Observations:

Part III: Reaction between zinc and acetic acid

Appearance of penny in vinegar after 30 minutes: Pretty dark coloured. Quite hard to see Lincoln’s head or the Memorial.

Part IV: Reaction between baking soda and vinegar

Description of what happened when the baking soda and vinegar were combined Immediately began foaming up and overflowing from the bowl. I also made a ziploc bag explode too.

Questions and conclusions:

Part I: Reaction between iron and oxygen

1. Write a balanced equation for the reaction between iron and oxygen.

4Fe + 3O2 —> 2Fe2O3

2. Classify the reaction that occurred between the iron and oxygen. Apply this reaction to a real-world situation.

It’s oxidation. Oxygen oxidizes from Fe to Fe3+. As for a real-world situation, well, rusting is a real-world application.

Part II: Decomposition of hydrogen peroxide

1. Write the balanced equation for the breakdown of hydrogen peroxide.

2H2O2 —> 2H2O + O2

2. Write a balanced equation for another decomposition reaction.

Decomposition for copper carbonate: CuCO3 → CuO + CO2

Part III: Reaction between zinc and acetic acid

1. Write the balanced equation for the reaction between zinc and acetic acid.

Zn(s) + 2CH3COOH(aq) —> Zn(OOCCH3)2(aq) + H2(g)

2. Classify the reaction between zinc and acetic acid and explain, in general terms, what happens during this type of reaction.

The reaction that’s happening is a oxidation-reduction chemical reaction, also known as a single-displacement reaction. It’s when an element or an

    Copper Reaction (Discussion)

    The reaction of copper with nitric acid resulted in a brown toxic gas, As the copper dissolved, the solution slowly turned blue because of the copper ions. this is the balanced equation for the reaction Cu(s) + 4H+(aq) + 2NO3-(aq)---> Cu2+(aq) +2NO2(g) + 2H2O(l) The reaction of aq copper nitrate with sodium hydroxide was the turning of the solution to a blue color, when water was added a cloudy mass of blue was formed below. This precipitate was copper (II) hydroxide. The precipitate was blue because of the copper ions. the balanced equation for this is Cu2+(s) + 2OH-(s) ---> Cu(OH)2O(s) The third reaction copper (II) hydroxide solution was heated, the solution turned from a bright blur precipitate turned into a black color and black precipitates were formed this is the reaction Cu(OH)2(s)---> CuO(s) + H2O(l) The fourth reaction, when copper (II) oxide was dissolved into 6M sulfuric acid the solution turnes into a blue-green color, in the end it turned into blue. The reaction is CuO(s) + 2H+(aq)---> Cu2+(aq) + H2O(l) When Zn metal is added to copper (II) sulfate it released a foul smelling gas which was hydrogen, , the Zn corroded into red precipitates but the solution retained its blue color. the reaction is Cu2+(aq) + Zn(s)---> Cu(s) +…

    Information on Iron and Hydrogen

    Like other group 8 elements, iron exists in a wide range of oxidation states, −2 to +8, although +2 and +3 are the most common. Elemental iron occurs in meteoroids and other low oxygen environments, but is reactive to oxygen and water. Fresh iron surfaces appear lustrous silvery-grey, but oxidize in normal air to give iron oxides, also known as rust. Unlike many other metals which form passivating oxide layers, iron oxides occupy more volume than iron metal, and thus iron oxides flake off and expose fresh surfaces for corrosion.…

    Oxygen and Oxidation

    Oxygen makes up only about 20% of the air, yet is the essential component for so many reactions. Without it fuels would not burn, iron would not rust and we would be unable to obtain energy from our food molecules through respiration. Indeed animal life on the planet did not evolve until a certain concentration of oxygen had built up in the atmosphere over 600 million years ago. The term oxidation has been in use for a long time to describe these and other reactions where oxygen is added. Oxidation, though, is only half of the story, as it is always accompanied by the opposite process reduction, which was originally thought of in terms of loss of oxygen. Later, however the terms widened to include a much broader range of reactions. We now define these two processes, oxidation and reduction, as occurring whenever electrons are transferred from one reactant to another – and many of these reactions does not involve oxygen at all. For example photosynthesis, the process in which plants store chemical energy from light energy, involve oxidation and reduction reactions although oxygen itself is not used. Transferring electrons from one substance to another leads to a flow of electrons, in other words to an electric current. Thus chemical reactions can be used to generate electricity – a simple battery works by using a reaction of oxidation and reduction in this way. As we will see, we can also reverse the process and use an electric current to drive a reaction to oxidation and reduction – this is the process known as electrolysis which has developed to become one of the most important industrial processes on which we depend. An understanding of oxidation and reduction is therefore at the heart of understanding a large branch of chemistry both in the laboratory and beyond.…
