SOLN 1
Solubility follows the general rule "like dissolves like"
Hexane is non polar whereas water is polar hence hexane and water when mixed will be immiscible
since water is more denser than hexane hence hexane will be on the top layer whereas water will be at bottom
According to HOMEWORKLIB POLICY only 1 question per post is allowed. please post the rest question seperately.
PLEASE LEAVE THE POSITIVE FEEDBACK IF YOU LIKE THE SOLUTION
Hand in this assignment as you ente Grade Name water and hexane miscible (soluble) or immiscible?...
What is the purpose of adding hexane to the aqueous solutions of halogens? (2 points) 2. Why do you discard solutions containing hexane in the separatory funnel instead of the organic waste container? (2 points) 3. Write the formulas for the diatomic halogens in order of increasing strength as an oxidizing agent. 4 Write the formulas for the halide anions in order of decreasing strength as a reducing 5. agent.
Section Name Experiment 12 Advance Study Assignment: The Alkaline Earths and the Halogens I. As pure clements, all of the halogens are diatomic molecular species, Their melting points are: F,, 54 K: Br 266 K; and I, 387 K. Using the Periodic Table, predict as best you can the molecular Cl., 172 1 formula of elemental astatine, At, the only radioactive element in this family. Also predict whether it will be a solid, liquid, or gas at rOom temperature. Elemental...
Equation for Part A above 1. Write net-ionic equations for the following precipitation reactions: a) The reaction between barium nitrate and sulfuric acid. b) The reaction between calcium nitrate and sodium oxalate. 2. Elements A, B, and C exist as the diatomic molecules A2, B2, and C2. All act as oxidizing agents, i.e., they take electrons from other species. In aqueous solution, A2 is green, B2 is yellow, and C2 is red. When they have gained electrons from other species,...
Construct a flow chart describing the seperation of the mixture and the isolation of each compound in this experiment. (Lab steps/procedures includes for reference) 4. Construct a flow chart describing the separation of the mixture and the isolation of each compound in this experiment. A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction...
Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
i need help with the postlab questions please Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
Introduction: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves because caffeine is more soluble in dichloromethane (140 mg/ml) than it is in water (22 mg/ml). However, there are...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
