Introduction When iron is mixed to Copper (Ⅱ) Chloride; the product will be copper and iron chloride. However‚ in this experiment‚ we do not have the information of the oxidation number for iron nails. There are 2 different oxidation numbers for iron; that are 2 or 3. We will need to check each of the equations to find out the moles of each element in the equation. Then we can compare the ratio between the mole and the mass of iron and copper; that will be measured during the experiment. Finally

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

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.

Formula and Percent Composition of the Compound Magnesium Oxide (MgO) Nice sounding title Date Performed Lab: 8/31/06 Purpose: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner in a crucible. Using molar masses of both magnesium and oxygen‚ an expected percent composition

Determining the Limiting Reactant and Percent Yield in a Precipitation Reaction Objectives: Observe the reaction between solutions of sodium carbonate and calcium chloride. Determine which of the reactants is the limiting reactant and which is the excess reactant. Determine the theoretical mass of precipitate that should form. Compare the actual mass with the theoretical mass of precipitate and calculate the percent yield. Materials: Balance 0.70 M sodium carbonate solution‚ Na2CO3(aq)

ion; it is added in excess to the oxidizing agent being determined. This would result to the formation of iodine which would be titrated with the standard thiosulfate solution. (2) For example in this experiement‚ the analyte that was used was copper in the form of CuSO4•H2O. It was strong enough to oxidize iodide ions to Iodine. The analyte was needed to be isolated‚ and we did this by precipitating it out of the solution. To precipitate out Cu (II) ions‚ NH3 was added dropwise – this is
