1-butanol yields 1-bromobutane in the presence of concentrated sulfuric acid and an excess of sodium bromide. CH3CH2CH2CH2OH (l) → CH3 CH2CH2CH2Br (l) If 15.89 mL of 1-butanol produced 12.23 g of 1-bromobutane, the percentage yield of the product equals: (Assume the density of 1-butanol is 0.81 g/mL, the molar mass of 1-butanol is 74 g/mol, and the molar mass of 1-bromobutane is 137 g/mol.) %
1-butanol yields 1-bromobutane in the presence of concentrated sulfuric acid and an excess of sodium bromide. CH3CH2CH,CH2OH (I) → CH3 CH2CH2CH2Br (1) If 13.55 mL of 1-butanol produced 13.23 g of 1-bromobutane, the percentage yield of the product equals: (Assume the density of 1-butanol is 0.81 g/mL, the molar mass of 1-butanol is 74 g/mol, and the molar mass of 1-bromobutane is 137 g/mol.) %
You are given the task to prepare the maximum possible amount of 1-bromobutane from the following amounts of available reagents: 1-butanol (4.9 mL, d=0.810 g/mL) concentrated sulfuric acid (3.7 mL, 18.4 M) sodium bromide (6.216 g) What is the limiting reagent? What is the theoretical yield?
Define the term limiting reagent.

Use the following reagent table for the reaction of : cyclohexanol + H2 SO4 → cyclohexene Chemical MW (g/mol) Density (g/mL) mmols used Amount used cyclohexanol 100.16 0.9624 1.50 mL Sulfuric Acid 98.08 1.83 1.00 mL cyclohexene 82.14 Using the information from the previous questions, if 0.95 g of cyclohexene were formed during the reaction, determine the % yield. Answer with 2 decimal places.
If exactly 3 moles of propanol (C3H8O) is combusted in the presence of excess oxygen (O2) for form carbon dioxide (CO2) and water (H2O), how many moles of water will be produced? Enter the integer number of moles of H2O, do not enter the unit. Hint: Since this problem and two problems below rely on this reaction, make sure you balance this reaction very carefully on paper as your first step before doing any calculations. The reaction to be balanced is reaction between C3H8O(l) and O2(g) to produce CO2(g) and H2O(l).
