One possible source of error that could have occurred relates to the methane gas that was used to prevent the recombination of oxygen and copper. This gas was pumped into the test tube, and fed into a flame as it came out. But, as this gas was moving into and out of the test tube, it could have been taking some of the red copper oxide particles with it. Because of this loss of copper oxide, you are losing both the elements of copper and oxygen, not just the oxygen. So, this causes the mass of the copper to be decreased from what it should be as not all of the copper particles from your original amount of copper oxide are accounted for. The mass of oxygen would then receive an increase because the sum of the element’s masses need to equal

    However, only experiments IV “Effect of Copper Metal” and V “Effect of Temperature” had reasonable results, so copper metal and temperature are the more effective factors. The less effective factors are the changes in concentrations of "H" ^"+" ions and "C" _"2" "O" _"4" "H" _"2" particles. This observation is represented in experiments II “Effect of "H" ^"+ " Ions” and III “Effect of "C" _"2" "O" _"4" "H" _"2" Concentration.” Both runs 2B and 2C had the fastest times of 25 seconds and 86 seconds

    Our procedure though was not without its mistakes. These mistakes are vital because they affect the data we conclude. Theoretically, according to the balanced chemical equation, for every mole of hydrated cobaltous chloride that is being heated, the decomposition ensures that the compound decomposes into one mole of cobalt(II) chloride and six moles of gaseous water vapor. Thus, in theory we should lose the mass equal to six moles of water vapor in each trial. Unfortunately, this is not the case because we don’t have perfect lab conditions and factors such as the time heated, utilization of the same crucible, and the inconsistency of magnitude of the flame from the Bunsen burner all contribute to differences in mass percent change for each

    In World War II the soldiers used a jelly-like substance, called “red vet pet” to prevent themselves from the sun. Finally, Benjamin Green combined this substance with cocoa butter and coconut oil, which created the new line of Coppertone suntan cream. Coppertone has come a long way, to make their product better. As they changed the product, the advertisement changed over the years to appeal to the audience. Although both of these advertisements are being presented to get people to buy Coppertone, the modern day advertising is more appealing than 1944 advertisement; the modern day advertisement has a better focal point, action, general feeling and mood, selection of elements, and audience.

    “The buyers of slaves had arrived. The other women and I were striped naked. I bit my lip, determined not to cry. But I couldn’t stop myself from screaming out as her arms were wrenched behind my back and tied,” sorrowfully cried Amari. The character, Amari, from the book Copper Sun by Sharon M. Draper, is 15 years old and was taken away from her homeland along with some members of her African tribe. They are now being taken against their will to different parts of the world to become slaves. Amari meets a strong and independent women, Afi, who keeps Amaris hope strong and increases her will to stay alive.

    An atom, by definition, is the smallest part of any substance. The atom has three main components that make it up: protons, neutrons, and electrons. The protons and neutrons are within the nucleus in the center of the atom. The electrons revolve around the nucleus in many orbitals. These orbitals consist of many different shapes, including circular, spiral, and many others. Protons are positively charged and electrons are negatively charged. Protons and electrons both have charge of equal magnitude (i.e. 1.602x10-19 coulombs). Neutrons have a neutral charge, and they, along with protons, are the majority of mass in an atom. Electron mass, though, is negligible. When an atom has a neutral charge, it is stable.

    The first possible source of error is the assumption that [OH-] does not change over the course of the experiment, even though it does. However, since the order of magnitude of [OH-] is so large compared to [CV] this error is miniscule. Another possible error is inaccuracies in the spectrometer, and for the calculation of the order of OH-, the measurement of the initial concentrations of the reactants. While these sources of error probably did contribute to slight differences in concentration, they were consistent and small enough to have little impact on the calculation of order, which is demonstrated by the extremely high R2 values (R2 >.999) for the graph of natural log of absorbance versus

    One possible source of experimental error could be not having a solid measurement of magnesium hydroxide nor citric acid. This is because we were told to measure out between 5.6g-5.8g for magnesium hydroxide and 14g-21g for citric acid. If accuracy measures how closely a measured value is to the accepted value and or true value, then accuracy may not have been an aspect that was achieved in this lab. Therefore, not having a solid precise measurement and accurate measurement was another source of experimental error.

  • What Role Does Copper Play In Azurite Formation

    614 Words  | 2 Pages

    Although not known for its abundance, azurite attracts attention for its rich blue color. According to the website geology.com, this mineral is a copper carbonate hydroxide composed of Cu3(CO3)2(OH)2. Due to the increasing copper price in the 21st century, copper mines have opened back up and it is here where we see how copper plays a major role in azurite formation. When there is a reaction between the subsurface copper ores and carbon-dioxide-laden waters descending into the Earth, the azurite creation cycle begins. Imagine a stream of dissolved copper being transported into a new environment. This environment could contain water chemistry or temperature which constantly changes, thus creating a potential area for the formation of secondary

    An Investigation into Electrolysis - Copper Sulphate Introduction Decomposition caused by electricity is called electrolysis. The electrical energy causes a chemical change. When a salt is dissolved in water, its ions become free to move so the solution can be "electrolyzed." The products of the electrolysis depend on the chemical solution, its strength and the type of electrode. The cathode is negatively charged and therefore attracts to it positive ions.

  • Electrolysis of Water and Copper

    1103 Words  | 3 Pages

    “Electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to an electric current being passed through the water.” As we know, water is a model of molecular compound, in which atoms are bounded with each other by sharing electrons. This type of bond is known as covalent bond. In order to divide the water solution into two constituents, Hydrogen H and oxygen O2, we use the method of water electrolysis. I predicted that we are going to separate water solution into hydrogen and oxygen substances by passing an electric current along them. The electric current charged negatively is called cathode, while electric current charged positively is called anode. Further, the positive charged ions (cations) are likely to step toward cathode, whilst negatively charged ions (anions) are likely to move toward anode. The reaction that happen during the electrolysis of water is described as below:
