all just agree that the penny should be removed? Is it possible that simple nostalgia and our fond memories of "take a penny‚ leave a penny" trays are protecting a coin that’s worthless to pretty much everyone besides the multinational conglomerate that helps produce it? And if not‚ why exactly is the penny worth keeping around? The penny for some time has been the “throw-away” change thus having a negative impact on the economy‚ because with all the accumulated pennies‚ is all the money thrown

the solid copper(II) nitrate is used to dissolve in a test tube filled with half distilled water. The solid copper(II) nitrate ionize in water to form copper(II) ions and nitrate ion. Hence‚ a blue solution is formed due to the blue copper(II) ion present in the solution. When excess solid is added‚ the solution will become saturated and do not allow any solid to dissolve‚ so excess solid will remain in the solution. This is shows that the equilibrium between solid and aqueous copper(II) nitrate

RESULTS AND DISCUSSION A redox titration involves the transfer of one electron from one reactant to another. The two reactions happen simultaneously.1 This experiment employed titration involving the use of iodine. Iodometry is the titration process where iodine is used as titrant for strong reducing agents. Another type of titration where iodine is involved is called iodometry‚ where iodine “is produced in-situ from the quantitative oxidation of iodide and then subsequently titrated with thiosulfate

Apache Indians My overall first impression of this oil on copper painting called Apache Indians by Ramon Torres in 1780‚ was the view of the 18th century lifestyle as apache indians. This painting depicts a great picture of their daily life and culture. The male out hunting to provide for his family while the female is providing for the family by nurturing the child. This painting leaves me wondering what the male is about to shoot the arrow at. I see the deer in the background‚ but it appears that

Introduction : Copper(II) sulphate‚ is a type of salt which it is formed by combining both copper ion and sulphate ion through the experiment of double displacement between dilute sulphuric acid ‚ and copper(II) carbonate ‚ . Through this process‚ the copper ion will displace the hydrogen ion as it is more electropositive and sulphate ion will displace carbonate ion as it is more electronegative. The resulting copper (II) sulphate solution when cooled can easily crystalize

passed from cancer and had been cremated. Her name was Penny. Penny was the sweetest‚ smartest dog‚ and anyone that met her came to this realization themselves. She was abused by her previous owners and in 2009 she was left in a backyard to die after they moved out. November 10th 2009‚ I got my little angel‚ and ever since then she has slept with me and followed me everywhere‚ even when I only moved five feet. If it weren’t for Penny‚ I wouldn’t be where I am today‚ and I probably wouldn’t
