A Study of Limiting/Excess Reactants: Synthesis of Lead (II) lodide Obiective: The purpose of this experiment is to study the concept of limiting and excess reactants, using the synthesis of lead (11) jodide from potassium iodide and lead (11) nitrate and to determine the yield of Pbl from this reaction. Concept: A chemical equation represents the stoichiometric proportions in which chemical...
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...

What is the limiting reagent in this experiment? Acetophenone or
aqueous bleach?
1. Add about 1.0 g (measured accurately) of acetophenone to 40 mL of the bleach solution (5% NaCl in water - this reactant should be included in your table of reagents!) in a 100 mL round bottom flask equipped with a magnetic stirrer. Clamp the flask in the fume hood above a stir plate. 2. After the initial reaction has subsided, boil the reaction mixture gently for 5...
CH 111 - Introduction to Inorganic and Organic Chemistry Lab 10 - Exp. 341 Synthesis of Strontium lodate In this lab, we will perform a synthesis reaction to generate a desired product. Synthesis reactions are performed in many different industries including fertilizers, plastics, pharmaceuticals and many others. The goal in a synthesis reaction is to generate and obtain as much of the desired product as possible. In this synthesis, the reaction between KIO, (potassium iodate) and Sr(NO3)2 (strontium nitrate) produces...
1. What is the theoretical yield + limiting/excess reagents
for experiment? [Please show working so I can understand,
thankyou!]
Phenylboronic acid; 183mg (1.5mmol)
Toulene; 2mls (0.5M of benzyl amine dissolved in toulene
solution)
Cu(OAc)2; 0.2mmol
2,6-lutidine; 1mmol
Myristic acid (ligand B); 91mg (0.4mmol)
I really need to know how to go about the two questions, please
show detail in your working out. Thankyou so much in advance.

I need help with the prelab and the flowchart. I’m totally
clueless on the flowchart.
For the prelab questions I have some answers but I don’t know
if they’re right. If they’re wrong, I would greatly appreciate an
explanation for the correct answer. I’m really trying to learn the
material but it’s hard now that classes are cancelled so I’m sorry
if these are dumb
1. PbCl ?
2. Ag+
3. ?
4. S1

I need help figuring out the flowchart and if I have the right
answers for the prelab please and thank you!
Group I, the Chloride Group BACKGROUND The precipitating reagent for the chloride group is chloride ion in an acidic solution. Only three of the 18 metal ions form a precipitate with this reagent: silver ion (Ag'), mercury(I)ion (Hg). and lead ion (Pb). Since lead chloride is somewhat soluble, it is not completely precipitated here, and a low concentration of...
