EXPERIMENT NO. 6 DETERMINATION OF THE MOLAR VOLUME OF A GAS AND THE UNIVERSAL GAS CONSTANT Salve‚ Ryan Angelo TAB3‚ Group 6‚ Mr. John Kevin Paulo Biadomang Tabor‚ Frances Hermilyn March 8‚ 2013 ------------------------------------------------- I. Abstract This experiment is working with the ideal gas law‚ which is the summation of Boyle’s Law‚ where pressure is inversely proportional to volume‚ Charles’ Law‚ where the volume is directly proportional to temperature and Avogadro’s Law‚ where

Thin Layer Chromatography Introduction Thin Layer Chromatography or TLC is a technique used as a separation and identification technique. There are many forms of chromatography‚ but one thing that remains constant throughout all of the types of chromatography is that there is a stationary phase and a mobile phase. In the case of TLC the stationary phase is the silica gel on the TLC tray. Procedure Chromatograph method is a method of separating mixtures of two or more compounds. Two phases

Background Information: When working in a lab‚ scientists often need to identify different molecules that are present in a sample they are studying. There are many ways to identify unknown molecules/chemicals in a sample. The method you will be using today is called Paper Chromatography and consists of 2 steps. First‚ you will separate the unknown chemicals and then you will identify

the Kool-Aid was correct. However‚ solely based upon the Rf values‚ the dyes in the green Kool-Aid are Red 40 and Yellow 6 as those are closet Rf value to the numeric data collected and calculated from the Kool-Aid chromatogram. However‚ the chromatography paper in both trials display that the dyes in Kool-Aid are a form of yellow and a form of blue because one color band was of a blue tint and the other‚ a yellow tint. Therefore‚ based on this qualitative data‚ the dyes in the green Kool-Aid are

city‚ heard a commotion outside his window early in the morning at about 3 a m. It was a chill December and all the windows of Chitre’s house were closed. As Chitre and his wife Rohini‚ seven months pregnant‚ opened the window‚ they got a whiff of gas. They immediately felt breathless and their eyes and noses began to stream with a yellow fluid. Sensing danger‚ the couple grabbed a bedsheet and ran out of the house. Unknown to them‚ all the neighbouring bungalows‚ which had telephones‚ had already

2. Justify your allocation based on your outlook for systematic risk in the U.S. Systematic risk is primarily based on the risks that are associated with actual or real events that may affect the market. This includes interest rates‚ inflation‚ wars and all that can affect the market and cannot be avoided through diversification. Systematic risk can be associated with riskier securities if and when compared to bonds. This rate of return is mainly unpredictable but can be profitable. My reasoning

Chromatography refers to a set of laboratory methods used in separating as well as purifying biomolecules. A variety of chromatography techniques exist‚ and all depend on the interaction between a stationary and a mobile state. Two types of chromatography methods were examined in this investigation. First‚ ion-exchange chromatography was used. This method separates ions and polar molecules based on their affinity to the ion exchanger [2]. Specifically‚ cation-exchange chromatography was performed

Research on gas masks I researched gas masks. I found out about: The history Gas masks were issued to all British civilians at the start of World War 2. In Britain fear was around because the British government thought that the Nazi German bombers would drop poison gas bombs. At the start of the war some citizens had not been issued with a gas mask. In a government document "If war should come" the explanation for this was that district leaders might have decided to keep gas masks in storage

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

Gas Laws Lab Introduction: The four basic physical properties of a gas sample are pressure‚ volume‚ temperature‚ and number of moles. The volume simply indicates the volume of the container since a gas will take up all space available to it. The temperature indicates the average kinetic energy of the gas particles. For gases‚ the temperature must be converted to the Kelvin unit. The pressure of the gas indicates the number of collisions with each other and the wall of the container. The number
