Mass Wasting Lab 03/15/2014-03/17/2014 GEY 111 Abstract My objective for this lab was to take various soil samples and recreate mass wasting with the various samples. This will allow me to better understand how mass wasting works in our environment. I preformed this lab by pouring samples onto trays and tilted the trays to recreate a landslide. I kept notes and created tables for each step of my experiment. The results from my experiment was that saturated samples hold together better

I. Purpose The purpose of this lab is to determine the molecular mass of a volatile liquid. II. Procedure • Place a cork with a small hole in it inside of a test tube and find the weight of the two together using a sensitive balance. • Pour 0.5 mL of the unknown volatile liquid into the test tube‚ insert the cork‚ and place the tube into boiling hot water while keeping the cork above water level. As the gas evaporates‚ excess gas will be released throughout the whole in the cork. Keep the test

The Effect of Different Molar Mass on the Diffusion on Substances Lunar-maius A. Gaerlan Group 2 Sec. X – 9l August 15‚ 2012 ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using agar-water gel test. The agar-water gel set up was composed of a petri dish of agar-water gel containing three wells. Drops of potassium permanganate (KMnO4)‚ potassium dichromate (K2Cr2O7) and methylene blue(C16H18N3SCl) were simultaneously introduced to each well. Methylene blue

Determining the Absorbance Maximum Wavelength and Molar Extinction Coefficient to Find the Molarity of the Unknown DCPIP Background Information: A spectrophotometer is an instrument used to help determine the absorption spectrum of chemicals. It does this by reading the absorbance of the chemical at different wavelengths. All chemicals absorb light in their own distinct way. This distinction helps to identify unknown chemicals. The absorption of light within a chemical is also very important because

Boiling Point Lab Introduction: The purpose of this lab is to learn about the calibration of a thermometer. In addition‚ we also investigated the boiling point of an unknown liquid to determine its identity. Chemical Responsibility: 1. Make sure to use glycerine (lubricant) and a towel to safely insert the thermometer into the rubber stopper. 2. Carefully operate the Bunsen burner and make sure to use rubber gloves when handling the boiling water of beaker 3. Always wear goggles

Melting Point Determination and Thermometer Calibration Lab Background: The melting point of a substance‚ a solid in this case‚ signifies the temperature at which the first crystal starts to melt until the temperature at which the last crystal disappears is reached. That being said‚ melting points are expressed in ranges‚ am organic compound will have a sharp range depending on the purity of the compound. Impurity of an organic substance will register an abnormal melting point based on its

Collecting Butane Gas The purpose of the lab was to determine the molecular mass of Butane‚ and this was done by using the ideal gas law (PV=nRT). The materials used were: match‚ funnel‚ bucket‚ cylinder‚ thermometer‚ lighter‚ scale‚ and a wooden flynt. These materials are used to help collect and test the Butane gas. Butane gas was used because it is ideal at standard temperature and pressure. Procedure: 1. Rinse bucket and fill three fourths full. 2. Rinse all glassware. 3. Place

I. Abstract: By manipulating the ideal gas law (PV=nRT)‚ we will be determining the molar mass of an unknown volatile liquid. Heating a flask filled with an unknown‚ easily evaporated liquid will allow for measurements that can be taken to work out the ideal gas equation. This lab will require knowledge of basic equations used in chemistry. Using these equations‚ such as density and number of moles(n)‚ we can substitute different values into the ideal gas law to manipulate it.
