#1 and # 2 pls. my previous answers were all wrong. REPORT SHEET FOR PERCENT YIELD...
Determining limiting reactant and percent yield Since this is our first synthesis experiment, this is a good place to review how to identify the imiting reactant and calculate the percent yield. I'll use some sample data to illustrate the process. CH CH2 HC OH HC H C CI CH CH t-butyl alcohol Density 0.7809 g/mL Conc. 0.42 g/mL MM-92.52 g/mol MM-79.2 g/mol Hydrochloric acid -butyl chloride MM-36 g/mol A student starts withmL of hydrochloric acid and-S mL t-butyl alcohol. She...
Please help me solve this and show the full calculations. Calculate the limiting reactant, theoretical yield, and percent yield using the following: 2.0 g of salicylic acid and 5 mL of acetic anhydride, along with 10 drops of phosphoric acid, were used to make acetylsalicylic acid. This is a 1:1 mole ratio.
help with all questions(: 1) Describe what the crystals look like? 2) If your percent yield is greater that 100%, give one plausible error you may have made. 3) Calculate the limiting reactant and theoretical yield of Cu for the following reaction: First balance the reaction CuSO4 (aq) + Al(s) → Al2(SO4)(aq) + Cu (S) 3.35 g 0.321 g 4) If the actual yield for the reaction in question (3) is 1.06 g, what is the percent yield for the...
please answer the following question. thankyou 21. [08 pts.] Consider the above reaction for preparation of t-butyl chloride (Mw. 92.57 gmol) from t-butyl alcohol (Mw. = 74.12 gimo) and hydrochloric acid (Mw = 36.46 g/mol) that you did in the lab. 7.0 gt-butyl alcohol reacted with 5.0 g hydrochloric acid to produce experimentally 7.0 gt-butyl chloride What is the limiting reactant? Calculate theoretical yield . Calculate percent yield 22. [03 pts.] A slightly polar organic compound distributes between diethyl ether...
answer it all please BS132 Experiment 3 2018-2019 The limiting reagent is the reagent which will completely react and so iIs excess. It will therefore be the reagent for which a lower number o present. Compare the respective molar proportions of the reagents used A and B above] and deduce which is the limiting reagent not in f moles are Igiven by Limiting reagent = 1 mark Scale of reaction (i.e. number of moles of limiting reagent used) - mol...

Use the Data provide below to answer question 1, 2 and 3: A Student is tasked with synthesizing butyl propanoate. The volume of butanol used: 4.60 ml The volume of propionic acid used: 7.50 ml Weight of butyl propanoate submitted: Vial with product - Empty Vial 14.727 g - 14.106 g = 0.621 g 1. Based on the information above, calculate the theoretical yield in grams (Show work for full credit): 2. Calculate the overall percent yield, based on the...
Aspirin can be synthesized in the lab by combining salicylic acid (C7H6O3) and acetic anhydride (C4H6O3) to form aspirin (C9H8O4) and acetic acid (C2H4O2).C2H4O2). The balanced equation for this reaction is C7H6O3+C4H6O3⟶C9H8O4+C2H4O2 A student started with 4.00 mL acetic anhydride (density=1.08 g/mL) and 2.07 g salicylic acid. The student synthesized 2.00 g of aspirin. Select the limiting reactant. acetic acid (C2H4O2) salicylic acid (C7H6O3) aspirin (C9H8O4) acetic anhydride (C4H6O3) Calculate the theoretical yield of aspirin (C9H8O4). theoretical yield: Calculate the...
