Student: Mary Chrisin L. ObreroDate: October 7‚ 2014 Section: 116 Behavior of Gases and Determination of Absolute Zero Experiments 4&5 Introduction: First of all‚ the Boyle’s law (pressure-volume law) indicates that the volume of a certain amount of gas given held at a constant temperature differentiates inversely with the applied pressure when there are constant temperature and mass. Equations: PV=C. When pressure goes up‚ volume goes down (derived from the equation above): P1V1 = P2V2 =

Purpose: The purpose of this experiment was to test and observe the physical and chemical properties of gases‚ and to use these properties to identify these gases when they are encountered. Procedure: Create a data table similar to that in the lab assistant to record your observations. Gather the following lab equipment: Goggles‚ test tubes‚ 24 well plate‚ Gas assembly with copper and plastic tubing and a #00 stopper‚ short stem pipet‚ rubber stopper #00 with one hole and a pipet tip with

Stratton 10/29/14 Period 6 Survey of Drama Reality vs. Illusion Generally speaking‚ plays normally incorporate a conflict that the characters struggle to conquer through the course of the play. Reality vs. illusion is a frequently used conflict that essentially broadens the mind of the characters and the audience. Reality is the awareness of something as a fact and illusion is misconception of an idea or belief. The central conflict of reality vs. illusion is respectively portrayed throughout

The purpose of this experiment is to discover the physical and chemical properties of the studied gases. In discovering these properties it allows the student or observer the ability to identify these gases when they come into contact with them. Procedure Before I began the procedure I gathered all my supplies from the given list in the manual. From there I began the actual experiment and diluted the HCL placed in a test tube and then placed the ZN in the tube as well. I placed the stopper

Experiment 2 Behavior of Gases PURPOSE This experiment has two parts. The purpose of part A of the experiment is to determine the atomic mass of a metallic element whereas the purpose of part B of the experiment is to determine the rate of diffusion of both gases hydrogen chloride and ammonia by measuring the distances travelled by the two gases in the same time period. For part A the reaction of the metal with the aqueous acid is as follows: M(s) + n H3O+ -----> M+n(aq) + n/2 H2(g) +

Experiment 4: Behavior of Gases Introduction: In this experiment‚ the problem trying to be solved is what gas laws are being used when the pressure‚ temperature‚ and volume are being measured. The three gas laws are Boyle’s Law‚ Charle’s Law‚ and Gay-Lussac’s Law. The Boyle’s Law is when volume and pressure are being compared. Pressure and volume are inversely proportional‚ because when pressure goes up‚ volume goes down. The Charle’s Law is when volume and temperature are compared. Volume and

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

INTRODUCTION [SLIDE 2] Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface‚ some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time‚ the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back

events like super-storm Sandy continue to increase in their frequency and severity? Many modern scientists attribute these dangerous environmental trends of global warming to the ‘greenhouse effect’. The ‘greenhouse effect’ results from greenhouse gases such as carbon dioxide rising into the atmosphere‚ trapping infrared radiation from the sun‚ and emitting ultraviolet radiation that can puncture the earth’s stratospheric ozone layer. A healthy ozone layer should prevent this from happening‚ but the

greenhouse effect in is the entrapment of the sun’s heat energy in the earth’s atmosphere. Greenhouse gases such as carbon dioxide‚ water vapor‚ methane‚ and nitrous oxides are all gases that contribute to this phenomenon. Carbon dioxide is the most abundant greenhouse gas while water vapor the least harmful gas makes up less than one percent of the gases in the atmosphere. These greenhouse gases are produced naturally by the earth for example carbon dioxide‚ and methane is produced from the waste
