Consider the above reaction using 25.0 ml of tert-butyl alcohol (d = 0.786 g/ml) with 60.0 ml of concentrated hydrobromic acid (d = 1.49 g/ml, 47.0% hbr). on a separate sheet calculate the theoretical yield in grams and the percent yield for a reaction that produced 26.1 g of tert-butyl bromide. clearly show the set ups to determine the limiting reactant and other calculations using proper units and significant figures. consult your textbook for the following two synthesis. keep in mind that conc. hcl and conc. hbr will not give good yields of alkyl halides by the reaction with primary and secondary alcohols. give the balanced equation to prepare chlorocyclohexane in good yield from cyclohexanol. give the balanced equation for the preparation in good yield of 1-bromopentane from 1-pentanol. the reverse of the reaction you performed in the lab can also occur. under the proper conditions, tertiary alkyl halides may undergo a hydrolysis reaction to form an alcohol and a hydrogen halide. complete and balance the following equation. (remember the general ii experiment? )

At 40 âc the solution has at 40 â c the solution has blank g of k n o 3 per 100 g of water and it can contain up to blank g of k n o 3 per 100 g of water. at 0 â c the solubility is ~ blank g k n o 3 per 100 g of water, so ~ blank g k n o 3 per 100 g of water will precipitate out of solution.g of kno3 per 100 g of water and it can contain up to at 40 â c the solution has blank g of k n o 3 per 100 g of water and it can contain up to blank g of k n o 3 per 100 g of water. at 0 â c the solubility is ~ blank g k n o 3 per 100 g of water, so ~ blank g k n o 3 per 100 g of water will precipitate out of solution.g of kno3 per 100 g of water. at 0 âc the solubility is ~ at 40 â c the solution has blank g of k n o 3 per 100 g of water and it can contain up to blank g of k n o 3 per 100 g of water. at 0 â c the solubility is ~ blank g k n o 3 per 100 g of water, so ~ blank g k n o 3 per 100 g of water will precipitate out of solution.kno3 per 100 g of water, so ~ at 40 â c the solution has blank g of k n o 3 per 100 g of water and it can contain up to blank g of k n o 3 per 100 g of water. at 0 â c the solubility is ~ blank g k n o 3 per 100 g of water, so ~ blank g k n o 3 per 100 g of water will precipitate out of solution.gkno3 per 100 g of water will precipitate out of solution. a kno3 solution containing 55 g of kno3 per 100.0 g of water is cooled from 40 ∘c to 0 ∘c. what will happen during cooling?
