for minority member’s affirmative action was put in place. Affirmative action is the outcome of a Civil Rights movement. It purpose was to cure discrimination‚ so people could uphold higher education and more job opportunities. The Criteria is race‚ disability‚ gender‚ ethnic origin‚ and age (Editors of Encyclopedia Britannica‚ 2017). Affirmative action is an action favoring those who tend to suffer from discrimination mostly from employment or education. This action was passed when there was heavy

than lower density salts would. . The data I collected shows potassium chloride‚ which has a density of 1.98 g/㎤‚ increased the solution’s temperature at a faster rate than any of the other solutions. Using the data I collected‚ I can unequivocally state that my data did not support my hypothesis. Potassium chloride had the fifth highest density out of the seven salts I used in my experiment. The highest density salt I used‚ sodium carbonate‚ had no change in temperature. I do not think there were any

12-STANDARDIZATION OF SODIUM HYDROXIDE Standard solutions for titrations are especially pure mixtures with exactly known concentrations. Primary standards are very pure solids. They have the advantage that they can be weighed (the analytical balance is normally the most accurate instrument in the laboratory) and they are stable under laboratory conditions. In this experiment‚ the primary standard is oxalic acid dihydrate‚ H2C2O4 ( 2H2O. It will be used to standardize a solution of sodium hydroxide

permeability of the cell increases enormously during the action potential. Comte Whitney Electricity is vital for neural function and communication. The semi-permeable membrane and presence of charged particles in solution (ions)‚ enables the cell to have control of an electric potential. The cell The concentrations of Na+ and K+ ions upon either side of a cell’s membrane are not equal. In order for the equilibrium to be restored‚ sodium will attempt to enter the cell‚ whilst potassium will exit

Prior to begin the experiment‚ preparation for some solutions is required to enhance the lab performance. The solutions needed are standardized potassium bromate‚ standardized sodium thiosulfate‚ and starch indicator. First‚ to prepare a starch indicator‚ pulverize 1g of soluble starch and add 15mL of water to make it as a paste-like substance. Dilute it with about 500mL of boiling water‚ and continue to heat until the mixture becomes clear. Cool it to room temperature and save it into a stoppered

Part B: 1. Take a 100 ml beaker and fill ¼ of it with water. Use a spatula to add some copper chloride dehydrate to the beaker filled with water. Record the observations. Be sure to observe the water and the copper chloride dehydrate. 2. Stir the contents in the beaker with

● Cobalt(II) Chloride Hexahydrate CoCl2.6H2O‚ was weighed in a weighing boat. The Cobalt(II) Chloride Hexahydrate was transferred into a 100mL volumetric flask dissolved in water. ● 25 mL of the dissolved was measured‚ using a graduated cylinder and few of the dissolved Cobalt (II) Chloride Hexahydrate‚ was poured into test tube. The test tube was labeled with a tape‚ to signify 25 mL and the spectrophotometer was used to record the U-V visible ABS (absorbance spectrum) with the wavelength of 515
