Developing Fuels * All gases take up the same volume under the same conditions. AT room temperature and room pressure this volume is 24 dm3. * Number of moles= volume in dm3 24 * Balanced equations can also be used to work out gas volumes. In the equations: 2Na + 2H2O 2NaOH + H2‚ where 15g of sodium is reacted‚ you can work out the volume of gas from working out the number of moles in 15g Na = 0.65 mol. Then you see that 2 mol of Na 1mol of H2‚ Thus 0.65 mol Na 0.325 mol H2. 0.325

natural or genetically modified plants; often together with their associated rhizospheric microorganisms which stimulates plant growth and decontaminates soil and water in conjunction with the plants. The plants extract heavy metals‚ natural aromatic and hydrocarbon compounds and also man-made chemicals such as pesticides‚ herbicides‚ fungicides‚ and antibiotics form the soil (Saier 2010). The Best part is this process uses minimal energy to run‚ all the plants need to use as energy is water‚ light and

PROPERTIES OF HYDROCARBONS Introduction Hydrocarbons are compounds which contain only carbon and hydrogen‚ can be classified into several types‚ depending on their structure. Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene) and alkynes (e.g. ethyne) have carbon-carbon double or triple bonds‚ and are said to be unsaturated. Aromatic hydrocarbons are cyclic compounds

A simple‚ rapid‚ specific and highly sensitive spectrofluorimetric method has been developed for the quantification of dabigatran etexilate mesylate (DAB) in bulk and capsule dosage form. A linear relationship was found between fluorescence intensity and DAB concentration in the range of 0.01-1.0 μg/ml in DMSO as solvent at an emission wavelength of 391 nm after excitation at 334 nm‚ with a good correlation coefficient (0.989). The detection and quantification limits were found to be 0.005 and 0

IMPACT OF URBANISATION ON BIODIVERSITY Case Studies From India WWF-India sees its role in urban work as an attempt to reduce the impact of cities on biodiversity and ecological footprint‚ both of which have implications for the overall conservation goals of the organisation. Further‚ given the experience and expertise in dealing with footprint issues‚ WWF feels there is a greater need to engage with planners‚ developers and policy makers involved in dealing with urban issues.

Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam currently made for thermal insulation and craft applications. It is owned and manufactured by The Dow Chemical Company. In the United States and Canada‚ the word Styrofoam refers to expanded (not extruded) polystyrene foam‚ such as disposable coffee cups‚ coolers‚ or cushioning material in packaging‚ which are typically white and are made of expanded polystyrene beads. This is a different material from the extruded polystyrene

Expt. 8.1 Thin Layer Chromatography (TLC) Analysis of Analgesics Krista Jinks CH 211L Section F 10/27/14 I. Abstract: The objective of this experiment was to analyze analgesic tablets by TLC to determine what analgesics they contain. The analgesics that could be in the tablets included ibuprofen‚ acetaminophen‚ aspirin‚ and caffeine. Through the use of TLC‚ unknown substance #62 was found to be Bayer Aspirin because it only contained aspirin. II. Introduction: 1. Briefly describe
