The world has so many problems that seem unrealistic to fix; poverty‚ bullying‚ terrorism global warming it’s overwhelming. Most people believe that homelessness is one of those but they are wrong. The solution to homelessness is to put the homeless people in homes. Specifically foreclosed homes. The ratio of foreclosed homes to homeless people in the United States is about six to one. Every single homeless person in the United States could be housed in a foreclosed home and there would still

Potatoes taste pretty good. Mashed‚ fried‚ baked‚ or scalloped‚ but how about taking the place of a car battery? If a potato can replace a AA battery and light up a light bulb‚ who’s to say multiple potatoes couldn’t serve the same purpose in a car? Potatoes use the acids within them to start a reaction between the copper and zinc wires on either side of it. This reaction causes the flow of electrons passing through the wires and using the positive and negatively charged electrons to power the

Chapter 7 Activity-Based Costing: A Tool to Aid Decision Making Solutions to Questions 7-1 Activity-based costing differs from traditional costing systems in a number of ways. In activity-based costing‚ nonmanufacturing as well as manufacturing costs may be assigned to products. And‚ some manufacturing costs—including the costs of idle capacity--may be excluded from product costs. An activity-based costing system typically includes a number of activity cost pools‚ each of which has its

Refining Solutions PHL/458 February 27‚ 2012 Refining Solutions When in search for a viable solution into refining ideas there are three main steps to follow. According to Vincent R. Ruggiero‚ the three steps to follow are to work out details by determining exactly how solutions will be applied. The next step is to examine each detail for imperfections‚ and the last step is to make any improvements that will eliminate the imperfections. In week two the original issue that was faced was

BUFFER SOLUTION (ACID) An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt. Objectives: 1. Measure the pH of the unknown solution first with indicators and then with pH paper. 2. compare the buffer solution with both a strong acid and a weak acid materials: 2 30 mL beakers 2 100mL volumetric flask 1 10mL pipet 2 aspirator 1 50mL graduated cylinder 1 10mL graduated

A buffer solution can maintains a narrow range of pH even when strong acid are added. In our experiment‚ we can see water is not a buffer‚ water can undergo very big changes when small amounts of strong acid or strong bases are added. When the strong acid‚ 100µl HCl was added into the dd water‚ the pH value changed from 7.38 to 5.83 which mean the dd water has turn into acid. The same phenomenon occurs while strong base‚ 100µl NaOH was added into the dd water. The pH value changed from 7.07 to 9
