Chemistry Revision F331 Isotopes - atoms with the same atomic number‚ but different mass numbers 131I - radioactive tracer for thyroid. 99Tc for tumours. Radioisotopes - gamma emitters & short half life - long enough to detect‚ but not long enough for damage. Beta particles emitters are more useful than alpha particle emitters because they penetrate more and so are more easily detected. Also‚ less damaging. The half life is the time taken for half the isotope to decay Mass left = initial

With my test result‚ it clearly shows that the concentration of sulfuric acid is 0.05 mol/dm3 using the concentration equation‚ c= n/v. 25 cm3 of the volume with sodium hydroxide is equal to 0.025 dm3 by dividing a thousand with cm 3 and multiply it with 0.1 mol/ dm3 which is the concentration of sodium hydroxide. With the ratio between sulfuric acid and sodium hydroxide is 1 to 2 so‚ 0.0025 should be divided by 2 and 0.00125 moles of sulfuric acid is come out. Finally‚ using c = m/v‚ 0.00125 mole/0

1. The final yield of the cells can be determined by use of an automated cell counter or by use of a hemocytometer (Neubauer chamber). In our laboratory‚ we determine the number of purified cells in a Neubauer-improved‚ bright line chamber with V-slash with a depth of 0.1 mm and a counting area of 0.0025 mm2 from Marienfeld (Lauda Königshofen‚ Germany‚ PN # 0650030). 2. For determination of the final cell yield‚ mix a 10 µl aliquot of the purified cells (Figure 9D) with 10 µl of trypan blue solution

Premium Energy Thermodynamics
difficult to derive the exact enthalpy in a reaction when multiple processes occur simultaneously. A method to circumvent this problem is outlined in Hess’s Law which was established in 1840. Hess’s Law states that the steps taken to determine the enthalpy of a reaction do not matter because the end results will be the same. This is the principle used for both parts of this experiment. In Part I of the experiment‚ two different reactions are performed to determine the enthalpy of formation for magnesium
