Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here

The Effect of pH Level of a Liquid on the Rate of Corrosion of Copper wire In this experiment‚ I will be testing the corrosion rate of copper wire after leaving them in different liquids with different pH levels. By doing so I will be able to determine which pH level corrodes copper the fastest. I will conduct this experiment by pouring 250mL of different liquids with different pH levels in cups‚ followed by an iron strip placed into the cup. A stopwatch will be timing how long it takes the iron

For this experiment me and my lab partner didn’t finish the experiment. We only end up to adding the magnesium sulfate. We added so much magnesium sulfate‚ and ended up drying the whole product without any liquid left. We were trying to do the procedure all over again but‚ we will ended up to not finishing the experiment still due to time constrain. I will try to explain the possibility what will happen up to the end of the experiment. After measuring the 10ml graduated cylinder‚ which is 27.27g

Percent Copper and Formula of a Copper Compound Sofia Economides Date Preformed: 3/19/2012 Date Submitted: 3/26/2012 Lab Partners: Anita Smith‚ Taylor Bell‚ Derek Bourgeois 1. Purpose a. To determine the percent of copper and the formula weight of a copper compound. 2. Introduction a. Magnesium is a very active metal which can reduce copper (II) ions in a weight sample of a compound to metallic copper. The reduction of copper ions in a compound to a copper metal

overhydration. In this paper I will discuss what over hydration is‚ the symptoms and effects of it and treatment options. What is over hydration? Overhydration is defined as a condition in which the body contains too much water (medical dictionary). There are two types of over hydration. First type is “Increased water intake” ()‚ or water excess and “Retaining water” ()‚ or water intoxication. Water intoxication is the type of over hydration where the body is taking in more water than the kidneys

sulphides in contact with air and water produces sulphuric acid which reduces the pH of water. The result of these reactions is increase in the solubility of heavy metals and consequently pollution of water resources. The Sarcheshmeh copper mine is one of the largest porphyry copper mines in the world which is located in south-eastern Iran. Chemical analysis of over than 600 water samples taken from streams and springs in the mining region and surrounding area of pit showed extensive changes in water quality

1. A serving of two cookies has 150 kcal and 12 grams of fat. What percentage of total calories is fat? Divide fat calories by the kilocalories Fat – 9 kcal 12g x 9kcal= 108 kcal 108kcal / 150 kcal = .72 .72 x 100 = 72% total calories from fat 2. How many grams of protein are in a 2400kcal diet with 15% of total kcal from protein? Grams / total kcal = total percentage of kcal from the protein Protein – 4kcal X / 2400kcal = .15 (15%) 2400kcal x .15 = 360 360 / 4kcal= 90 gm of

The mean data observed show a number of trends. The average weight and length tend to decrease as the amount of Ammonium Sulfate approaches the full recommended dose. On the other hand‚ the average amount of protein per gram of tissue tends to increase as the amount of Ammonium Sulfate approaches the full recommended dose. Our null hypothesis was that there is no difference between the mean weights or the mean lengths of the seedlings two different treatments. (A+B‚ A+C‚ and B+C) Each of these
