He was a police detective at San Francisco until his wife Trudy was killed in a car bombing incident. This led him to a nervous breakdown and got him discharged from his department. In all the cases he solved‚ it was only his wife that he was not able solve. He did not go out of his house for three and a half years. Sharona Fleming a nurse and an assistant

I. INTRODUCTION Hydatidiform Mole (H-mole or Gestational trophoblastic disease) is abnormal proliferation and then degeneration of the trophoblastic villi (Garg & Giuntoli‚ 2007). As the cells degenerate‚ they become filled with fluid and appear as clear fluid-filled‚ grape-sized vesicles. The embryo fails to develop beyond a primitive start. Abnormal trophoblast cells must be identified because they are associated with choriocarcinoma‚ a rapidly metastasizing malignancy. (Pillitteri‚ 2010)

CuSO4.H2O‚ we need to find the ratio of mole between anhydrous copper II sulfate and the water vapour by using the formula: In this case‚ the molar mass of: Copper II sulfate (CuSO4) is: 63.55 + 32.06 + 15.99 x 4 = 159.57 g/mol Water (H2O) is: 1.01 x 2 + 15.99 = 18.01 g/mol (e.g. 0.37/18.01= 0.02054 mol.) Then‚ is obtained by: Calculation 1st attempt 2nd attempt 3rd attempt Mole of water (mol) = 0.06163 Mole of anhydrous copper sulfate (CuSO4) (mol)

Finding the Ratio of Moles of Reactants in a Chemical Reaction Purpose: The goal of the lab is to determine the mole ratio of two reactants in a chemical reaction (AgNO3 and K2CrO4). However‚ the formulas for the products are unknown. Introduction: When determining the molar ratio of a chemical equation‚ usually the formulas of the reactants and the products are known. With that information‚ it is particularly easy to determine the ratio. However‚ since the products and the formulas for

Title: Finding the Ratio of Mole of Reactants in a Chemical Reaction Purpose of Lab: To find the coefficients of two chemical reactants that appears in a balanced chemical equation using the continuous variations method. Pre Lab Questions: 1. 2AgNO3(aq) + K2CrO4(aq) → 2KNO3(aq) + Ag2CrO4(s) 2. There is enough to make a valid conclusion because‚ on the graph‚ one can clearly see that the two lines intersect. Thus‚ one can also determine the mole ratio. The mole ratio is approximately 2:1

RESEARCH QUESTIONWhat is the number of moles of water of crystallization associated with one mole of copper (II) sulfate‚ in the hydrate CuSO4 * xH2O (s)? The independent variable in this experiment is sample thermal treatment ( heating and cooling) and the dependent variable is the number of moles of water of crystallization. A number of other variables can affect the final result of the experiment: whether the crucible

Using the Method of Continuous Variations to Determine the Mole Ratio between Reactants Abstract: The purpose of this lab was to find the molar ratio of NaClO and an unknown substance labeled solution “B”. Using the method of continuous variation the ratio of the two solutions were changed but kept equal to 50 mL. The reaction was an exothermic oxidation-reduction and the temperature change was measured to determine which ratio of NaClO to solution “B” was optimal. The ratio with the highest temperature
