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 following atomic weights & quantities to
calculate 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 ot 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....

Question 4 Status: Not yet answered | Points possible: 1.00 Suppose you are titrating an acid of unknown concentration with a standardized base. At the beginning of the titration, you read the base titrant volume as 2.86 mL. After running the titration and reaching the endpoint, you read the base titrant volume as 21.17 mL. What volume, in mL, of base was required for the titration? Type answer: Question 6 Status: Not yet answered Points possible: 1.00 Suppose you are...

Ester= Isoamyl acetate (banana) Molar mass of banana= 130.19 density= 0.876 g/ml 5.26 g ester product. Alcohol= isoamyl alcohol density= 0.81 g/ml Molar mass= 88.148 g/mol Quantity= 5.4 ml Carboxylic acid= acetic acid density= 1.05 g/ml Molar mass= 60.052 g/mol Quantity= 11.4 ml and 1 ml of concentrated H2SO4 (1.8 g, 0.018 mole) was also used in the procedure. Calculate theoretical yield and % yield .
