Abstract:
A specific amount of Copper will undergo several chemical reactions and then recovered as a solid copper. A and percent recovery will be calculated and sources of loss or gain will be determined. The percent recovery for this experiment was 20.46%.
Introduction:
The purpose of this experiment is to demonstrate the different types of chemical reactions, those including Copper.
There are different types of chemical reactions. A double displacement reaction is a chemical process involving the exchange of bonds between two reacting chemical species. A a decomposition reaction is the separation of a chemical compound into elements or simpler compounds and the single-displacement reaction is a type of

Balanced Chemical Equation:
Cu(s) + 4HNO3(aq) —> Cu(NO3)2 (aq) + 2NO2 (g) + 2H2O (l)
Reaction 2: when sodium hydroxide (NaOH) is added to copper (II) nitrate (Cu(NO3)2), a double displacement reaction will occur. Copper and sodium will displace each other to create copper (II) hydroxide and sodium nitrate.
Balanced Chemical Equation:
Cu(NO3)2 (aq) + 2NaOH (aq) —> CuOH2 (s) + 2NaNO3 (aq)
Reaction 3: When copper (II) hydroxide is heated, a decomposition reaction will occur. The reaction will decompose forming two compounds, Copper (II) oxide, and water.
Balanced Chemical Equation:
Cu(OH)2 (s) + Heat —> CuO (s) + H2O (g)
Reaction 4: when a sulphuric acid is added to the solution that contains copper (II) oxide, a double displacement reaction will occur. the copper (II) oxide will react with the sulphuric acid producing copper (II) sulfate and water. The copper and hydrogen gas replace each other. Balanced Chemical Equation:
CuO (s) + H2SO4 (aq) —> CuSO4 (aq) + H2O (l)
Reaction 5: when zinc is added to the copper (II) sulfate solution, a single displacement reaction will occur. The zinc will form a new compound with the sulfate, and the copper will stay as a metal.
