There are a few qualities that a boss must have to be qualified as a good supervisor. First‚ a good supervisor must have excellent people management skills. He or she should be able to assign the right person for the right job. This requires ability to judge a junior’s strengths and weaknesses and provide him right opportunities to enhance his strengths and overcome his weaknesses. Secondly‚ a good supervisor should have in-depth knowledge about his functional area. This is essential so that the

Methane CH4 = (6.022 x 1023 atoms/mole) = 6.022x1023 atoms of Methane in one mole 6. In this experiment‚ the pressure (P) was 1 atm‚ the temperature (T) was 295 K‚ the volume (V) was 0.150 L‚ and the number of moles (n)was 6.2 x 10-3 moles. The ideal gas law states that P*V = n*R*T. Based on your experiment‚ what value do you get for R? Is your value close to the standard

Introduction: The goal of this experiment was to measure the amount of gas produced in various reactions. The Ideal Gas Law was needed in order to calculate the mass of reactants and moles of gas produced: ‚ where is the pressure in atm‚ is the volume in Liters‚ is the number of moles‚ is the ideal gas constant [0.082 (Latm)/(Kmol)]‚ and is the temperature in Kelvins. Considering the units on R‚ it was important to convert pressure‚ volume‚ and temperature to atm‚ L‚ and K‚ respectively. In

Ideal Gas Law: The ideal gas law is the equation of state of a hypothetical ideal gas. It obeys Boyle’s Law and Charles Law. Ideal Gas Law Formula : General Gas Equation: PV = nRT Pressure(P) = nRT / V Volume(V) = nRT / P Temperature(T) = PV / nR Moles of Gas(n) = PV / RT where‚ P = pressure‚ V = volume‚ n = moles of gas‚ T = temperature‚ R = 8.314 J K-1 mol-1‚ ideal gas constant. Ideal Gas Law Example: Case 1: Find the volume from the 0.250 moles gas at 200kpa and 300K temperature

Ideal Gas Law Lab 1. Procedure: First‚ we used a balance to weigh the canister of gas‚ and recorded that mass as the original weight. Then‚ we filled a large bucket with water and recorded the temperature. We then filled a small test tube with water at the same temperature and poured that water into a graduated cylinder to measure the original volume of water in the tube. We then poured the water back into the test tube and placed the tube into the bucket with the opening upwards‚ turning the

Analysis of a Chemical Mixture Using the Ideal Gas Law The objective of this experiment was to determine the composition of the NaNO2 mixture in the net ionic reaction of NO2-(aq) + HSO3NH2(aq) → HSO4-(aq) + H2O(l) + N2(g) in unknown mixture number nine. It was known that NO2-(aq) and HSO3NH2(aq) were in a stoichiometric 1:1 molar ratio. In trial one the percent mass of NaNO2 in the unknown mixture was 59.30%. In trial two‚ the percent mass of NaNO2 was 63.47%. Lastly in trial three
