Lin‚ Alan Spring 2013 Linguistics 1 Properties of Language According to Linguistics Language‚ we use it everyday‚ but what exactly defines “language?” Are there generalizations to be made of all languages? Does everyone learn language same way? What are the rules of language? “What is Language?” by Neil Smith and Deirdre Wilson answers these questions and more by highlighting the three major theories of modern linguistics. The first modern linguistic theory claims that language is govern

claimed that by growing and using transport biofuels in the UK‚ carbon dioxide emissions could be cut by 50 – 60% compared to those from fossil fuels‚ as well as reducing the need for foreign imports‚ and so could lead to a reduction in greenhouse gases. This is backed up by an article which states that farmers in the UK see biofuels as a way of providing the nations motorists with a low carbon fuel supply (Kendall‚ 2006). Kendall makes clear that the demand for both fuel and food crops could be met

Lab: Comparison of Three Isomers of Butanol Pre-lab: 1. Write the general reaction of an alcohol and HCl. 2. What would the solubility be of an alcohol in water. 3. What would the solubility be of an alkyl halide in water? 4. What is the purpose of KMnO4 in the reactions? Safety: Concentrated hydrochloric acid is corrosive and the vapour is very irritating to the respiratory system. Avoid contact with skin‚ eyes‚ clothing‚ and the lab bench. Wear eye protection and a lab apron.

water is lost through the leaves of plants‚ at the same time water is being absorbed and pulled up the plants roots to be replenished. 2. Describe any experimental controls used in the Investigation. -The environmental controls used in this lab were heat‚ wind and light (sun). 3. What environmental factors that you tested increased the rate of transpiration? Was the rate of transpiration increased for all plants tested? -Wind and heat were the factors that consistently increased the

Physical Properties of Organic Molecules Abstract Identifying the physical properties of compounds can be useful in several ways. It helps us to determine the structure of certain compounds‚ the purity of substances and if a substance is not pure we can figure out how to separate contaminating substances from a compound. In this experiment‚ I learned how to determine a solid’s melting point and why some melting point ranges may be broader than others.

Since the Grignard reagent can easily react with water‚ all glassware including the 25 ml round bottom flask‚ magnetic stir bar‚ 3 and 5 ml conical vial‚ 50 mL Erlenmeyer flask‚ claisen adapter‚ drying tube and 5 glass pasteur pipets were first added to a 250mL beaker and placed in the oven for 30 minutes. After the completion of the thirty minutes‚ 0.150 g of shiny magnesium turnings and a stir bar was first added to the round bottom flask and the claisen adapter along with the drying tube packed

Lab questions: 1. Based on my observation CaCl2 is soluble in water. 2. When 15% of HCl was added to CaCl2 as the teacher was performing the experiment I observed and realized some changes took place physically

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
