Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However‚ the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50°C or more. If the boiling points are too close‚ this method

Manappallil Mrs.Scanlon Narrative Remembering essay Our Gas Station Almost 10 years ago‚ my dad put some money into a share for a gas station to help my uncle out. So I guess it’s our family business and in whatever way we can help‚ we should help out. My grandfather works there like every day and some times he needs help with carrying things. I come with him to the store and once we get to our gas station‚ I arrange everything in the little storage room with my grandfather’s

contains aspirin (acetylsalicylic acid)‚ citric acid‚ and sodium bicarbonate. As the tablet dissolves in water‚ the bicarbonate ions in the tablet react with the hydrogen ions from the acids that are also contained in the tablet. The carbon dioxide gas produced by the reaction is what causes the bubbling that can be observed. HCO3- (aq) + H+ (aq) → H2O (l) + CO2 (g) In this investigation‚ you will design two experiments which will compare two different factors that may affect the rate of the

OIL AND GAS EXPLORATION: INTERROGATING THE OIL COMPANY’S ADHERENCE TO ARTICLE 40 ON COMMUNITY COMPENSATION Indigenous communities across the globe have been victims of unwarranted exploitation by private investors in the search for among others oil and gas. Whenever governments and oil companies intend to enrich themselves from the oil revenue‚ history has indicated that voiceless citizens are subjected to inhuman treatment and torture‚ deprivation of their indigenous community rights‚ disruption

Gas chromatography (GC) is a chromatography technique where the separation of individual components (analytes) from a sample relies on their differing distribution between a mobile and stationary phase. The mobile phase carries the analytes through the stationary phase. In GC‚ it’s an inert gas (usually helium or nitrogen). The gas must be inert‚ so it won’t react with the sample to give a false reading. The stationary phase is a substance fixed in place to which the sample adsorbs because

The Bhopal disaster‚ also referred to as the Bhopal gas tragedy‚ was a gas leak incident in India‚ considered the world’s worst industrial disaster.[1] It occurred on the night of 2–3 December 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal‚ Madhya Pradesh. Over 500‚000 people were exposed tomethyl isocyanate gas and other chemicals. The toxic substance made its way in and around the shantytowns located near the plant.[2] Estimates vary on the death toll. The official immediate
