A Cycle of Copper Reactions

A Cycle of bullshit Reactions
Observations:
1.) In the first measuring rod we put a piece of slovenly person wire in a beaker and added 4.0 ml of (16M) HNO3 which was go across. When we first added the HNO3 the compartmentalisation began to form bubbles. After delay a few seconds the multifariousness began to turn form clear to a green transparent liquid. And the last thing that happened was the mixture formed a brown transparent gas.
2.) In flavour 2 we added 30ml of (3M) NaOH, which was again clear, to the copper precipitate. When we added the NaOH the solution glum from a green transparent liquid to a turquoise groggy and gelatin same(p) liquid.
3.) In stride 3 we alter the solution over a Bunsen burner while brainchild it. After we heated it for a couple of minutes the mixture turned to a dark green almost fateful looking precipitate.
4.) In step 4 there wasnt any change because we just decanted it, which means we used water supply to rinse it.
5.) In step 5 we added 15ml of (6M) H2SO4. When we added the H2SO4 the solution turned back to a translucent blue liquid.
6.) In step 6 we added 4 grams of zinc to the solution. When we added the zinc it immediately began to fizz followed by the formation or red clay like solid that floated on the surface of the solution.

Reaction 1: crap metal To hair Nitrate
Cu(s) + 4HNO3(aq) Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
Cu + 4H1+ + 4NO31- Cu2+ + 2NO31- + 2NO2 + 2H2O
Cu + 4H1+ + 2NO31- Cu2+ + 2NO2 + 2H2O

Reaction 2: Copper Nitrate to Copper Hydroxide
Cu(NO3)2(aq) + 2NaOH(aq) 2NaNO3(aq) + Cu(OH)2(s)
Cu2+ + 2(NO3)1- + 2Na1+ + 2OH1- 2Na1+ + 2NO31- + Cu(OH)2
Cu2+ + 2OH1- Cu(OH)2

Reaction 3: Copper hydroxide to copper oxide
Cu(OH)2(s) + heat CuO(s) + H2O(g)

Reaction 4: Copper oxide to copper sulfate
CuO(s) + H2SO4(aq) CuSO4(aq) H2O(l)
CuO + 2H1+ + SO42- Cu2+ +SO42- + H2O
CuO + 2H1+ Cu2+ + H2O

Reaction 5: Copper sulfate to copper metal
CuSO4(aq) + Zn(s) ZnSO4(aq) + Cu(s)
Cu2+ + SO42- + Zn Zn2+ +SO42- +Cu
Cu2+ + Zn Zn2+ + CuIf you want to get a wide of the mark essay, order it on our website: Orderessay
