Jordan Toschak Kevin Hannon and Megan Blanford Physical Properties of Clusters of Galaxies Monday (4/15/2013) Procedure For this experiment‚ a photograph of the Virgo Cluster of Galaxies will be needed to observe. The photograph will be sectioned into specific areas with coordinates like a map. Locate the area and identify the galaxies. Classify the galaxies as elliptical‚ spiral‚ or irregular. An elliptical galaxy will appear solid with not real defined “arms” or spirals coming from the

Introduction The purpose of this lab was to explore the properties of an unknown compound. An unknown was given and a cation flame test and anion test was performed to determine the identity of the compound. Once the identity was determined‚ the properties were explored. Experimental To determine the cation of the compound‚ a cation flame test was performed. A bunsen burner was lit until a medium blue flame was burning. The given unknown was scooped onto a nichrome wire loop. The wire was held

Hydrogen and the Noble Gases Hydrogen is the chemical element with atomic number 1. It is represented by the symbol “H”. It is an odorless‚ nonmetallic‚ tasteless and highly explosive gas. Hydrogen is the lightest and most abundant chemical element in the universe. It forms 1- ions when combined with metals‚ and 1+ ion when combined with non-metals to form acids. Hydrogen is “the fuel of life”; without it to combine with oxygen we would not have water. Water is made of two parts hydrogen

Thomas Graham studied the behavior of the diffusion of gases of unequal densities when placed in contact with each other‚ using air as his control. He wanted to numerically prove how the diffusion of the gas volumes was inversely proportional to the value of the density of the gas‚ under constant temperature and pressure. The significance of this experiment was that in led to a reevaluation of the concept of the movement of matter‚ realizing that diffusion dealt with small immeasurable elements

solutions into two categories‚ colligative properties and non-Colligative properties. Colligative properties are different from non-colligative properties because they focus on the dissolved particles‚ not the solute itself. Non-colligative properties depend on the specification of the dissolved particles and the solvent. Colligative properties are properties that depend on the dissolved solutes in the solution. There are four main colligative properties; vapor pressure‚ freezing point‚ boiling point

Title: Physical and Chemical Properties Purpose: To investigate the physical and chemical properties of pure substances as distinguishing characteristics. Procedure: 1. Set up a well plate with 24 pieces and fill two with either Dilute HCl or Dilute NaOH. 2. Set up four test tubes with any single substance in each one. 3. Observe and record original color and odor of substance. 4. Light flame with matches. -Hold test tube with substance in it over flame with clamps -Observe and record

Kinetic theory of gases Question: How does odor travel from one place to another? Kinetic theory of gases A gas is composed of atoms or molecules The gas particles are in constant random motion Kinetic energy is transferred between particles as they collide Pressure The force exerted per unit of area Formula: pressure/force area Measured by barometer A vacuum is empty space‚ with no particles or pressure. Atmospheric pressure is the collision air particles with objects Units of
