Gas Exchange

Gas Exchange To complete this worksheet, select: Module: Gas Exchange and pH Balance Activity: Animations Title: Gas Exchange Introduction 1. a. Describe the respiratory system role with oxygen and carbon dioxide. The respiratory system is responsible for the movement of gases involved in cellular metabolism. b. Why is oxygen needed? Oxygen is needed because it is used up during the aerobic breakdown of glucose. c. What generates CO2? Carbon dioxide arises from the aerobic...

Gas Stations

Do Gas Stations cause soil pollution? Soils are extremely important parts of every ecosystem. They are a home to many microbes and provide vital nutrients to the plants that live in them. pH is the measure of acidity or alkalinity of a solution, and most organisms have a very small range of pH values in which they can survive. 7 is considered neutral, lower than 7 is acidic (lemon juice, rain water) and above 7 is basic (bleach, soap). Lots of urban areas are dependent on car transportation...

Gas Chromatography

Gas Chromatography: Purifying alcohol Introduction The goal of this lab is to understand the principles of chromatography by purifying alcohol using fractional distillation. Running standards with gas chromatography we were able to see and calibrate our data to find not only how much ethanol our alcohol attained but also what a mixed unknown sample contained. Chromatography is a way of being able to separate substances in solution that can help not only identify the analytes (the studied...

Evaluation of the Gas Law Constant

Vanessa Gale Formal Lab: Evaluation of the Gas Law Constant Dr. Monzyk Due 06/25/2012 Purpose: The purpose of this lab is to evaluate the gas law constant. The ideal gas law is represented as PV=nRT, where R represents the gas law constant. To determine R, we must find the other parameters, P, V, n and T through the experiment. Equipment and Materials: Large beaker Ring stand Clamp Copper wire 100 mL eudiometer tube Magnesium (Mg) ribbon M6 H2SO4 (Sulfuric Acid) Wash bottle...

Gas Pressure and Volume Relationship

Gas Pressure and Volume Relationships Exp. E-1A A. Obtain a pressure-measuring device as indicated by your lab instructor. Obtain a 60 mL syringe, fill it with air, and connect the syringe to the gas-measuring device as indicated in the figure. Test your apparatus for gas leaks. If you can't eliminate all leaks, see your lab instructor. B. If necessary, calibrate your gas-measuring device as indicated by your lab instructor. Fill your syringe to the largest volume mark on the syringe and reconnect...

exhaust gas treament

Engineering Workshop 1 Exhaust Gas Treatment Index of contents Introduction Waste gas with harmful traces of gas must be burned in an afterburner. To destroy the harmful traces the temperature after the burner must achieve 900°C. The preheater can`t resist a temperature of 700°C. Therefore quench water in a mixer will be used to protect the heat exchanger. The waste gas has the following properties: Waste gas composition: Mole fraction(= 0,9890...

Gas Chromatography

Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to...
