Copper Cycle Lab Essay

PurposeDuring this experiment, we were trying to see whether dogshit, after a chain of chemic reactions, will revert back to its portional form.ProcedureFirst, I added azotic point with sloven in a beaker, which turned into a shit nitrate, a blue-green dissolvent. Afterwards, I added atomic number 11 hydroxide, and my solution colored to a dark blue solution called copper color hydroxide. I heated the solution to evaporate the water and I got a brownish-blackish solid called copper oxide. at one time the solid appeared, I poured in sulphuric acid to it and I got copper sulfate, a bluish solution. The final step I took was to add the agent coat, which turned the solution from blue to clear, with a brown solid in the bottom of the beaker, copper.ObservationDuring each step, something happened. For instant, for the first step, when I added the acid to the copper, the copper disappeared and the solution turned from the clear acid color to a blue-greenish hue. In the next ste p, there was another chemical reaction when I added the sodium hydroxide. The whole solution turned blue when I stirred the mixture. When the time came to evaporate the solution, the liquids disappeared, leaving behind a wet, brownish solid in the middle of the beaker. When the solid was hot, it bubbled and popped until it cooled down. When all the liquids evaporated, I scraped off the solid and lay it in a separate beaker. Once I put the sulfuric acid in it, the brown solids (copper oxide) slowly dissolved and turned the acid into blue. After the acid was blue, I added the metal/grey colored zinc into the solution the solution bubbled and the zinc turned the solution clear. The zinc disappeared and in its place, copper appeared.AnalysisFor each step, there was a chemical reaction, and for the part where we evaporated the water/liquefied chemicals. For each step, I was turning the copper into a compound. When an acid was added to the copper, it turned the element into a compound. When a footstall was added later, it merely replaced the acid with the base.ConclusionFor this experiment, I can conclude that an element/ number can never be destroyed or created. The copper cycle is evidence for the Law of Conservation of Mass, which states that an element or matter can never be created or destroyed, only changed.
