In Alfred Wallace’s article‚ The War in Cardboard and Ink: Fifty Years of Civil War Board Games‚ he provides insight and examples of how war games have advanced since they were first released. Details supporting the advancement include; video games‚ addressing conflicts‚ audience‚ popularity‚ materials‚ and art cover. Throughout the article‚ Wallace provides four ways war games are played; board games‚ miniature games‚ solitaire games‚ and video games. Although Wallace also claims that‚ video games

Gas chromatography is the common method used for the biogasoline analysis. Biogasoline catalytic cracking process requires detailed qualitative and quantitative analysis of the hydrocarbon composition of its oil and fraction. In this analysis‚ their fractional composition‚ saturated vapor pressure‚ density and antiknock rating will be investigated. By knowing the qualitative and quantitative composition of the gasolines‚ the content of n-paraffin‚ isoparaffin‚ aromatic‚ naphthene‚ and olefin (PIANO)

Alkenes from Alcohols: Analysis of a Mixture by Gas Chromatography Aim: To analyze a mixture of alkenes by gas chromatography. Introduction: In this lab‚ we specifically used elimination reaction; however we only used the E1 reaction. In the presence of strong acids‚ alcohols protonate to form a good leaving group‚ namely water. Upon loss of a proton to a good leaving group‚ an introduction of unsaturation (a double bond) can be preformed. According to Wikipedia‚ an E2 reaction is typically

Silveira Date of Submission: September 25‚ 2013 Lab Section: CHE110L*Z Purpose The purpose of this experiment is to use two common laboratory methods to see how mixtures can be separated based on physical properties. Paper chromatography will be used to separate the dye colors from M&M candy to see which colors contain yellow #5. Gravimetric separation will be used to separate salt and sand from a mixture. Procedure The procedure for this lab can be found on pages 16 – 30 in “General Chemistry

AP Lab #5 Plant Pigments/Photosynthesis I. Identifying the Effects of Different Variables of Light and Carbon Dioxide on the Rate of Photosynthesis and Observing the Separation of Pigments Through Chromatography II. Introduction Plants have a variety of pigments‚ all of which absorb a different color of light. The three main pigments are chlorophyll a‚ chlorophyll b and carotenoids. Chlorophyll a is the primary plant pigment that absorbs red and blue light‚ which ultimately appears green to the human eye
