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

Properties of Water Introduction: Water’s chemical description is H2O. As the diagram to the left shows‚ that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom‚ resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side‚ where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract‚ water

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

The Justification of Private Property Property Law JURI 25066EL Ryan Waschulzik 0271075 March 4th 2015 Words: 1772 Pages: 8 The notion of property is one that has long preceded us‚ or anyone we know. We know that the earliest social theory of property originated in the works of Saint Thomas Aquinas who had said that humans have a natural right to the use of or ownership of an unspecified amount of property. He also said that the amount of property to which you are entitled‚ is based

July 28st‚ 2014 Lab #10 Properties of Light Purpose: The ideal purpose of this lab activity is to investigate the relationship between the frequency of the light (color) and the energy produced by different colors of light. Other purposes of this experiment include calculating the proper current for each LED‚ measuring the evaporation rate of rubbing alcohol‚ and being able to discuss the outcome of the relationship in light energy and the color of the light producing the energy.

Christian Hall NT 1310 Physical Networking Lab 3.1 Building a New Structure- Tools and Wiring Structured Cabling Where is the Plenum section of the room and why is it important? The plenum space is where the communication cables for the building ’s computer and telephone network are stored. What is the purpose of Riser cabling? The purpose of riser cabling is so the cables can be situated into walls rather than a drop ceiling. These cables run between floors in non-plenum areas is rated as

Cognitive Properties Ashley Weber Principles of Chemistry 2 Experiment 1 02/02/2015 Abstract: Several experiments were performed to observe the colligative properties. This includes the freezing point depression‚ and osmotic pressure. Two ice baths were made‚ one with pure water‚ the other with salt water. The lowest temperature was then record for each bath and compared. The salt water had a lower freezing point than the pure water by 2 degrees which supports the hypothesis that solutions have

This essay assesses property dualism‚ a theory of mind. It proclaims the existence of a single‚ physical substance (unlike Cartesian dualism)‚ but argues that this single substance has two potential properties: physical and mental states that are not reducible. The idea that mental states are non-reducible properties of brain states is the central tenant of a theory of mind called property dualism. However‚ before we can assess the theory we must be aware that the question assumes the existence
