- How do I calculate the percent yield based on the limiting reactant in this bromination of trans-cinnamic acid reaction? (See attachments for further information)0.149 g of trans-cinnamic acid was initial mass of the alkene 1.0 mL of glacial acetic acid (AcOH) was used 1.0 mL of Br2 was used 0.128 g of (2R, 3S)/(2S, 3R)-2,3-dibromo-3-phenylpropanoic acid was the final mas of the productdettol (C8H9ClO) + Clorox (Cl) what gives ? (Please type answer)Use the following atomic weights and quantities to calculate the overall % yield of diphenylacetylene. Remember that your yield must be based on the limiting reagent, and that grams must be converted to moles. For problems not involving a one to one stoichiometry it may be easier to calculate the theoretical yield in grams from both reagents to determine which is truly the limiting reagent. Filling out most of the chart will help. Give only two significant digits in your answer. If after rounding the answer is a whole number, do not include a decimal point. C = 12, H = 1, Br = 80, K = 39, O = 16 formula formula weight grams moles Answer: stilbene dibromide + potassium hydroxide 19.704 1.459 theoretical yield (g) % yield diphenylacetylene 2.063

Use the data in the Table to determine in which direction the equilibrium lie for each of the following reactions? a. CH3CO2H + CH3CH2O b. CH3CONH2 + F CH3CO2 + CH3CH2OH CH3CONH + HE C. H20 + NH2 OH + NH3Acetanilide (C6H5NHCOCH3, M = 135.2) can beprepared from aniline (C6H5NH2, M = 93.1) and aceticanhydride ([CH3CO]2O, M = 102.1) according to thebalanced equation below. C6H5NH2 + (CH3CO)2O →C6H5NHCOCH3 + CH3COOH If 10.0 g acetanilide is isolated from the reaction of 10.0g aniline with 10.0 g acetic anhydride, what is the percentyield of the reaction?
- 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).In Grignard reaction experiment, 0.6458 g of Mg (molar mass 24.305 g/mol), 2.03 ml of 2-bromopropane (density 1.31 g/ml, molar mass 122.99 g/mol, and 1.23 ml. of 4-anisaldehyde (density 1.12 g/mL, molar mass 136.15 g/mol) are used. Assuming H3PO4 is in excess, theoretical yield of the final product (molar mass 180.24 g/mol) is g Note: Input numerical value only, Do not include unit. Pay attention to significant figures.Q5.)
