- A mixture of ethanol, benzaldehyde and KMnO4 is mixed together. Would you expect a precipitate to form based on the reactants functional groups?when chloromethane dissolves in liquid ammonia what is the dominant solvent-solvent interactionIf a mixture is distilled rapidly, the separation of its compound is poorer than if the mixture is distilled slowly. Please explain why is that so using your own understanding. I don't need a copy-pasted answer from google.

- Give the definition of the inductive effect. What is the reason for its appearance in the molecule? Show the effect of the inductive effect in molecules: bromoethane CH3CH3Br; ethanol CH3CH2OH; fluoroethane CH3CH2F.Supposed you are in a chemistry laboratory gave you a 500 ml Erlenmeyer flask containing 200 ml of heterogenous liquid mixture. This liquid mixture consists of sodium chloride, water, benzoic acid, is made by combining Mixture A and Mixture B. Mixture A (aqueous mixture): sodium chloride is dissolved in distilled water. Mixture B (organic mixture): benzoic acid, phenol and aniline is dissolved in petroleum ether (a nonpolar solvent). Your task is to separate the components of the heterogenous mixture and identify the components. What wet chemical analysis/qualitative test should be performed to detect the compounds?Oral rehydration salts are stated to contain the following components: Sodium Chloride 3.5g Potassium Chloride 1.5g Sodium Citrate 2.9g Anhydrous Glucose 20.0g 8.342 g of oral rehydration salts are dissolved in 500 ml of water. 5 ml of the solution is diluted to 100 ml and then 5 ml is taken from the diluted sample and is diluted to 100 ml. The sodium content of the sample is then determined by flame photometry. The sodium salts used to prepare the mixture were: Trisodium citrate hydrate (C6H5Na3O7, 2H2O) MW 294.1 and sodium chloride (NaCl) NW 58.5. Atomic weight of Na = 23. The content of Na in the diluted sample was determined to be 0.3210 mg/100 ml. Determine the % of stated content of Na in the sample. The stated should be 104.5, how??
