Lab 2: Separation of Mixtures and Solids Purpose: The purpose of this lab is to become familiar with the separations of mixtures and solids. Pre-lab predictions: Data: Data Table 1: Experiment Data | | Grams | Percentage of Mixture | Iron Filings | 2.0g | 26.67% | Sand | 1.6g | 21.33% | Table Salt | 2.4g | 32.00% | Benzoic Acid | 1.2g | 16.00% | Total | 7.5g | 96% | Observations: While the water was boiling with the three solids (salt‚ benzoic acid‚ and sand) the water got

Separation of a Mixture of Solids My Flow Chart First remove iron filings with magnet since this is the only substance in the mixture that it is magnetic and will be attracted to a magnet. Second remove the sand by adding the mixture to hot water‚ which the other two substances are soluble. Third remove the benzoic acid since this is less soluble in cold than salt by cooling the mixture in the heated water. This will then leave the table salt behind in the water as the last substance.

Experiment 55: A Separation and Purification Scheme The final lab report/procedure write-up will consist of the following: Report guide: 1. List the names‚ structures‚ and amounts of each compound in your mixture. 2. Draw a flow chart (like pg 687 in PLKE) showing how you separated and isolated your two compounds. Be sure to include the structures of the compounds at each step. 3. Write a procedure. This should include exactly how you performed your separation. It should have enough

Furthermore‚ the separation of powers provides a system of “shared power known as Checks and Balances.” The three branches that are created in the Constitution are Article 1 (Legislative Branch)

Katie Arrington 09/18/2012 09/19/2012 Title: Separation of Mixtures and Solids Purpose: The purpose of this experiment was to practice the process of separating mixtures of different solids. Procedure: This experiment consisted of different processes to separate a mixture of solids into the four individual solids: sand‚ benzoic acid‚ iron fillings‚ and sodium chloride. To remove the iron fillings from the mixture I used a magnet and scanned it across the entire mixture and the magnet

of the Constitution gave this country purpose; a want to become a naturalized citizen of this country. Separation of Powers is very intrinsic‚ for the different types of government. In Document 4‚ the Legislative Branch makes the laws. The Executive Branch carries out and enforces the laws. The Judicial Branch interprets laws and punishes those who break the laws that are enforced. The Separation of Powers is very vital to this country‚ in ways such the Executive Branch has all of the power‚ and no
