The purpose of this experiment is to use our knowledge from previous experiments to separate a copper compound and from there make calculations relevant to the experiment. The calculations that we had to make in this experiment had to do with finding the percentage of copper in copper compound and from there find the formula weight of the copper compound.
Question or Problem
The question that was proposed by the instructor for investigation was: Can the % composition of an element in a compound be determined accurately (Lab Manual 61)?
For this experiment we have to use physical and chemical methods to separate the copper from the copper compound. In this experiment one physical method and one chemical method was used. The physical method that was used was filtration which is the separation of a solid from a liquid by passing the liquid through a porous material, such as filter paper. The chemical process used involved mixing a chemical into the compound to separate the copper from the compound (Lab Manual 33).
Sample Calculations and Equations
In this experiment there were three different equations used and they were, The Net Ionic Equation, Calculating the percent of copper, and the last one was a mathematical formula that represents the relationship between theoretical percent copper of a particular compound and its formula weight (Lab Manual 61). The last equation was changed in order to find the fwt, so I will provide the edited equation also.

...sition of an element in a compound accurately. To do that I used one physical methods and one chemical method to obtain the copper from the compound. The physical method was filtration and the chemical method involved pouring certain chemicals into the compound to separate the copper from it. I was unable to fulfill the experiment due to an error in the experiment which effected mathematical equations negatively and in turn gave me a faulty result. I believe the experiment was a failure due to the possibility of an inaccurate measure of one of the chemicals or compound which gave out faulty results. In conclusion my experiment was a failure due to a mistake in the experiment.

- ... The absorbance recorded for the sample being tested can be matched with a concentration using the graph generated by the standards. Ultraviolet-Visible Spectroscopy Spectroscopy involves the measurement of light absorbed or emitted from a sample. In ultraviolet-visible spectroscopy (UV-Vis), light in the ultraviolet-visible region has the same energy as energy levels for some of the electrons in molecules, so absorption of this radiation will excite electrons in a molecule to higher energy orbitals....

- For over two thousand years, people have been cultivating and consuming Asparagus officinalis. During this time some people have observed a peculiar manifestation of an odd odor in their urine shortly after ingesting this vegetable (Mitchel and Waring 2014). This particular stench has been described as smelling like boiled cabbage (Mitchel et al. 1987, Pelchat et al. 2011). Many experiments have contributed this smell to sulfurous molecules found in the urine after asparagus ingestion, the most common molecules found being methanethiol and dimethyl sulfide (Lison et al....

- Every chemical element or compound have specific properties that make them different than the other. However, these properties help us to understand every element or compound in which they can be used and how we can deal with them. These properties can be chemical properties which are defined as "that property must lead to a change in the substances ' chemical structure", such as heat of combustion and flammability ("Physical and Chemical…"). Also, these properties can be physical properties which are defined as the properties "that can be measured or observed without changing the chemical nature of the substance", such as mass, volume, boiling and freezing points ("Physical and Chemical…")....

- Going through a divorce is typically traumatizing, not only to the married but also to the entire family. The separation of couples is due to a wide range of factors that vary accordingly. These include but are not limited to affairs, financial issues, distrust, inability to communicate, lack of intimacy, loss of feelings for one another, and stress. Without a doubt, divorce is a very discouraging thing for people to endure. The people often overlooked throughout the process of a divorce, surprisingly enough, are the children....

- The identity of the mysterious unknown compound substance Guadalupe Rueda* & Alexia Tipton CHEM 111-457 Introduction There may be a time when a scientist or chemist doesn’t know the identity of a ionic compound. This can cause complications or a hazard if it’s utilized without knowing what that compounds is or can do. The only solution would be wot use a set of chemical cation/anion tests in order to identify the unknown compound. By going through elimination and confirmation tests, it is easier to identify the unknown compounds by narrowing the possible options based on the solutions formed....

- When the Constitution was created, the developers and opposers of the new government both felt that this new government needed to provide the people with shielding from the abuse of power of the federal government. Incorporated in the Constitution was three strategies to protect the citizens from misuse of control which consisted of the separation of powers, the Bill of Rights and federalism. These three approaches provide rights/freedoms to the people, limitations and balance of government. One of the strategies of the prevention of abuse by the government, which wasn 't exactly stated in the Constitution, but presented in Articles 1, 2 and 3 was the separation of powers(Lowi, Ginsberg, an...

- The doctrine of the ‘separation of powers’ is a concept that concerns the system of governance, it suggests that there should be an appropriate distribution of power between the different principal institutions of the state . The separation of powers emphasises the functional independence of these branches, and especially that their subsequent actors do not possess powers attributable or assigned to other institutions . This concept is popularly construed with the tripartite division proposed by Montesquieu in The Spirit of the Laws (1748), which details the need for distinction and independence between the executive, legislative and judicial branches, so to effect benefits such as a safegua...

- Weil 1 Copper is one of the earliest elements known to man. Because of its distinct red color, Copper is very easily identified. In the ancient times, copper could be found lying in the ground in its unattached state without interaction to other substances. Copper and its compounds have many uses in today’s society. Copper has many chemical properties that make it unique. The Atomic number of copper is 29. An Atomic number is a measure of the amount of protons in the nucleus of an atom....
