Work procedure of solid phase micro extraction should be explained. Necessity of cold trapping at the time of injection in the solid phase micro extraction procedure has to be explained. Whether all the unknown analyte is extracted into the fiber in solid state micro extraction has to be explained. Concept Introduction: Solid phase micro extraction is a sampling technique. Here analyte from liquid or gas is extracted into a thin coating with the help of a syringe. After extraction the fiber is transferred to the separating instruments such as gas chromatograph or mass spectrometer. Here desorption of analyte takes place and analysis is started.

For each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3solution, the solution is basic (pH ~10), and the color is ["", "", "", "", ""] . At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is ["", "", "", "", ""] . When you weren't paying attention and added too much HCl (~12 mL extra), the color is ["", "", "", "", ""] . When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color is

The following reaction is run in which the initial conditions include only methane (CH4) at a concentration of0.115 M. Once equilibrium was established, the concentration of acetylene (C2H2) was measured to be 0.035M. What is the value of the equilibrium constant, K?2 CH4 (g) ⇋ C2H2 (g) + 3 H2 (g)

Calculate the equilibrium concentration of carbon dioxide for the following reaction:2 COF2 (g) ⇋ CF4 (g) + CO2 (g) Kc = 2.00 at 10.00 °C. at equilibrium [COF2] = 0.255M; [CF4] = 0.118M
