unfenced Mexico-Arizona border‚ so one of the best solutions would be to add fencing along the border‚ as many political leaders have suggested. According to the Washington Post‚ in 2007‚ President Bush proposed the construction of 700 miles of vehicle barriers and fencing along this border. If President Bush’s plan is implemented‚ the amount of unfenced border would be reduced to 1300 miles‚ making it tougher for illegal immigrants to cross. Another solution for weak border security is sending additional

in part 1‚ Ag+‚ Pb+‚ and Hg22+ were presented to the student in aqueous solutions and then precipitated through experimentation. In part 2‚ the same procedure was enacted to determine which substances precipitated through qualitative analysis. Solubility rules were also a major theme as solubility is important in determining whether a reaction will produce a precipitate. Starting out the experiment‚ HCl was added to the solution in the test-tube in order to form a reaction between the HCl‚ Ag‚
