|[pic] |[pic] |[pic] | The partial pressures in the bottom row were found by multiplying the mole fraction of each gas by the total pressure: Pi = XiPt. The term in the denominator of each mole fraction is the total number of moles of gas present at equilibrium: (0.200 – x) + (3.00 + x) + x = 3.20 + x. Substituting the equilibrium partial pressures into the equilibrium expression‚ we have [pic] whose polynomial form is 4

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

A Report into the concept and effects of Merchandise Display Densities 1. Define the Concept of store merchandise display densities. Store merchandise display density describes the amount of product per foot on display. A foot is the approximate size of the display rail‚ it is perceived as a unit‚ rather than a measurement. The product is counted in styles‚ the unique design of the product‚ and options‚ its available colour variations. Primark has on one foot only one stile in one option

Place the lit match about one inch above the wick in the path of the gas. Try again if there is nothing happened. If it does‚ see if the same thing happens if the lit math is held higher

Ketchup Lab Report Problem: People visiting fast food restaurants complained that ketchup was dripping onto their fingers and clothes. What could we do to insure that the ketchup will not drop all over the customers? Hypothesis: If I put one ketchup packet in a hotter bath then it will move faster down the styrofoam plate. Independent Variable: The temperature Dependent Variable: The viscosity of the ketchup’s “runniness” Constants: The type of ketchup

ABSTRACT: This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis‚ helping lower the energy needed to activate the reaction while the enzyme itself is not affected. Catalase is a digestive enzyme used to break down hydrogen peroxide‚ which is a normal byproduct of cellular respiration. The reaction could take place without the help of catalase‚ but

Thermodynamics- Enthalpy of Reaction and Hess’s Law December 5‚ 2011 Kylie Case‚ Emma McKee‚ Rebecca Smith Purpose: In this lab‚ the purpose was to verify Hess’s Law. Theory: Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The first being enthalpy of reaction‚ ΔHrxn‚ which is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant

Formal Lab Report | Chemistry | | Student name: Sara Hattar Grade: 10 ”C” | | Teacher: Christine Ziadat | | | Title: Investigating the effects of changing the concentration of an acid on the rate of reaction between HCl and Magnesium. Aim: In this experiment we are going to see the effects of using three different concentrations of HCl when added to Magnesium metal on the rate of reaction. Hypothesis: If the concentration of the acid increased in reaction between HCl (the acid)

et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the independent variable is the light
