    content. The silver-copper alloy will be dissolved in nitric acid‚ the silver will be precipitated as silver chloride‚ and the silver chloride will be filtered‚ washed‚ dried and its mass determined. From the mass of the silver chloride formed and the mass of the original sample‚ you will be able to calculate the percent of silver in the alloy. Because the results are based on the mass of a product‚ this procedure is classified as a gravimetric analysis. Silver and copper are very nonreactive

    Determination of Water in a Hydrate DESIGN – Aspect 1: Defining the problem & selecting variables Research Question: What percentage of Copper Sulfate Hydrate is water? Background Information: There are many ionic compounds that contain one or more waters of hydration in their formulae. They exists either in anhydrous or hydrated form. Most anhydrous compounds have a strong tendency to absorb water from the humidity in the atmosphere and shifts into a hydrated form. Because of

    experiment you will investigate the reaction of copper metal with oxygen in the air. Using stoichiometry‚ you can predict the amount of copper oxide (CuO) that could be produced if all the copper would react. However‚ when you perform the reaction yourself‚ you will discover that only some of the copper reacts to form black copper oxide. A stoichiometric calculation will allow you to determine the amount of copper oxide produced and the amount of unreacted copper remaining. In the second part of the experiment

    The connections with Karl Marx‚ Martin Luther King Jr.‚ and Henry David Thoreau can be summarized as similar and contradicting. Each individual are similar‚ because they all have their personal view in regards to human society. However‚ with their new and unique views entering the human society‚ not everyone will accept and follow it. Therefore‚ it causes conflicts and contradiction among the people. To demonstrate these connections‚ I’ll use specific examples from their works. They considered

    11 3/5/2013 Purpose: To determine the percent by mass of water in a hydrate of copper (II) sulfate hydrate.  Hypothesis: I hypothesize that when the solution is heated the hydrate will convert to an anhydrous ionic compound. Then the percentage composition will be determined by weighing the mass of the white crystals. Materials: 400ml beaker‚ hot plate‚ tongs‚ scoopula‚ electronic balance‚ glass rod‚ hot pad‚ and 4g of hydrated copper (II) sulfate Procedure: 1. Measure the mass
