Aluminum Foil In Copper Chloride
When we placed the aluminum foil in copper chloride, a chemical reaction occurred. Before the reaction took place we had aluminum foil and copper chloride as our reactants. After the reaction happened, the products were aluminum chloride and copper. After the foil was placed in the copper chloride, the color of the aluminum foil had changed from a shiny silver, to a deep red. Also, the color of the copper chloride changed from a light blue to a murky green. At the start, there was aluminum and copper chloride. During the reaction, the aluminum and copper chloride atoms rearranged to form aluminum chloride and copper as two separate substances, also being different substances than the ones that we started out with. A chemical reaction is when
Stoichiometry Lab Report
930 Words | 4 PagesAfter placing the aluminum in said beaker, one should gather a stir stick and stir the solution in order to speed up the reaction. One should stir the solution until there are no visible silver pieces of aluminum left in the beaker of what was the copper (II) chloride solution. When there are no visible silver pieces of aluminum left in the beaker, this means that the reaction has occurred. After the reaction has occurred, one needs to separate the products, which are copper and aluminum chloride, from each other in order to see how much copper was able to be produced. Seeing as the products are a solid in the form of copper and a liquid in the form of aluminum chloride, the process of filtration can be used to separate them.
Why Is Litmus Paper Is Used To Identify Metal Ions
1204 Words | 5 PagesWhen the students placed the wire containing the sample in the flame it burned a orange/ red color. when this result was compared with the previous flame tests it could have resulted from either CaCl2 or NaCl. Both of these compounds produced an orange flame. After the flame test was conducted, the students performed a litmus test to identify whether the unknown was neutral or a base. When exposed to the red and blue litmus paper, no reaction occurred.

761 Words | 4 PagesA mixture of elements is what is known as compounds. Chemical reactions occur when particles react with each other and atoms in molecules get rearranged. Reactions happen either rapidly or slowly. The speed of a reaction is known as the rate of the reaction. This speed of chemical reaction depends on many factors such as temperature, particle size of reactants, and the intensity of reactants.
Copper Cycle Synthesis
578 Words | 3 PagesIn this reaction NaOH was added to the Cu(NO3)2. The solution developed a precipitate which made the clear solution become cloudy and uniform in color (blue). The physical color change was demonstrated through the formation of the precipitate. The third step was the formation of CuO. In this reaction, the Cu(OH)2 product was heated on a hot plate and stirred continuously until the solution became colorless and a dark precipitate formed.

In this experiment, an iron nail was placed in a solution of Copper (||) Chloride that was dissolved with water in a baby food jar. Observations were taken over the next three (schools) days.
Double Displacement Lab Report
873 Words | 4 PagesSodium cabonate, the second compund, was added to the various different metal solutions, the first compound, these two different compounds switch places. As my hypothesis states this reaction is called a double displacement because two different compounds switch places. We know that this is a double displacement reaction because the metal solutions reacted with the sodium carbonate making it evident another reaction is taking place. We know this reaction occured because many different chemical changes were evident such as metals changed colour and dissolved, as well as the solutions changed colour and turned

800 Words | 4 PagesIntroduction: 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
Comparing The Structures And Designs Of Copper
194 Words | 1 PagesThere are a lot of structures and designs that go into atoms. The element copper has many features. Copper has the atomic symbol Cu, the atomic mass 63.55, and the atomic number 29. Copper has 29 electrons and protons, and has 34 neutrons. The main components that make up the atom are the protons, electrons, and neutrons.

Each time the solution changed color, a precipitate formed, or when gas appeared, indicated that a chemical reaction was occurring. For the first reaction, copper was added to nitric acid, forming the aqueous copper (II) nitrate (where the copper went), along with liquid water, and
