counterfeit. In an attempt to stop this‚ Tiffany made several demands to eBay. One of which‚ eBay refused‚ resulting in Tiffany filing a lawsuit. Tiffany argued that eBay was responsible for contributory infringement‚ false advertising and trademark dilution. eBay won on all counts‚ arguing that eBay did not have specific knowledge of counterfeit items being sold‚ that there was nothing actually false about the items being sold‚ and that eBay was not liable because they did not try to confuse Tiffany’s

adding the acid solution? – so that the drops from the funnel will not fall into the burette. 3. In using a burette‚ why is it important to (a) rinse it with a little of the solution it is going to contain? – to remove any residual water and so avoid dilution of the acid solution when it is poured into the burette. (b) to clamp it vertically? – to enable the liquid level to be read correctly. (c) to have the part below the tap full? – to ensure that the actual volume of liquid delivered into the flask

No; the experiment was not successful‚ because it did not show the correct fluorescence gradation of the serial dilution of the DNA concentration. As shown by the picture‚ only the first drop of the DNA/EtBr mixture for the DNA standards fluoresce brightly under the UV light‚ while the other spots for both the DNA standards and the unknown DNA standards were all dimly fluoresce. This was due to pipetting error; the tip of the pipette did not touch the liquid (TE) in the micro-centrifuge‚ so no DNA

1. What is the molarity of a solution of ammonium chloride prepared by diluting 50.00 mL of a 3.79 M NH4Cl solution to 2.00 L? 2. A student takes a sample of KOH stock solution and dilutes it with 100.0 mLof water. The student determines that the diluted solution is 0.046 M KOH‚ but has forgotten to record the volume of the original stock solution sample. The concentration of the stock solution is 2.09 M. What was the volume of the original sample of stock solution? 3. A chemist wants to prepare
