Discuss the mechanism for the chemiluminescence of luminol.
Organic Chemistry Post Lab Questions for the Synthesis of Luminol synthesis of Luminol from 3-nitrophthalic acid and hydrazide 1. A. Draw a well-labeled diagram which shows the singlet state, singlet excited state and the triplet state in a energy level diagram. Show the spin of electrons in each of these states. B. Show transitions in your diagram and label the radiative processes as either phosphorescence or fluorescence C. Discuss which of these are "allowed "transitions and which are "forbidden" transitions....
A) Bunny's compound is insoluble in water, or aqueous acid, but soluble in aqueous NaOH. It also gave a definite rotation of- 0.3° in the polarimeter. It showed a strong absorbance at 1710 cm in the IR spectrum. Bunny has compound (letter): Explain: B) Buffy's compound was not soluble in water, aqueous acid, or aqueous base. It has no optical rotation. Her compound's IR is shown. Buffy has compound (letter): included): Explain (with at least one point from the IR...
1. Ionic solids easily dissolve in water. Using sodium chloride as an example, explain the mechanism by which the dissolution is made possible. 5. Describe the typical characteristic of hygroscopic food substances. 2. Describe the roles dipole and hydrogen bonding play in the dissolution of polar molecules in water. 3. Crackers have an aof 0.3. What happens when they are exposed to air with 80% relative humidity? 4. What is a Moisture Sorption Isotherm (MSI)? 1. Ionic solids easily dissolve...
Charcoal does not dissolve In either water or soluble in liquid CS_2. Sulfur does not dissolve in water, but is soluble in liquid CS_2. Potassium nitrate dissolves in water, but is insoluble in liquid CS_2. Outline a procedure for separating the three substances.
a - please do not forget to say why it doesnt dissolve in water b- specific to this experiment. This is not asking why excess hydride would be used or what its used for. This is asking for a yes or no answer with an explanation (sorry the other students who posted this same question got answers that do not actually answer the question). Why does the vanillin dissolve in an aqueous NaOH solution but not in water? Is H...
Amines are basic compounds that dissolve in water upon treatment with aqueous acid. a. Write a balanced chemical equation to illustrate the reaction between HCI and trimethylamine IN(CHalal. b. Use the reaction to explain why amines may be soluble in aqueous HCI but not in water
Question 3 3 pts Zinc hydroxide, Zn(OH)2, is considered insoluble in water. Is it true that no Zn(OH)2 can dissolve in water? You must explain your answer in words. You may also use chemical reactions. Please use complete sentences. HTML Editon Part BIVA-AI EI31* 1. 12pt true, zinc hydroxide is insoluble in water because the equilibrium will shift more towards the left Zn(OH)2(s) -->Zn2+ (aq)+ 2OH'(aq) only small amount of solid will dissolve 33 words р 3 pts
1. How does water dissolve minerals? 2. Under what circumstances cause minerals to precipitate from water?
Please help asap =) 2. Lead(II)chloride is insoluble in water Kap PbCn 1.7x10-) and silver chloride is very insoluble in water (Ksp Agci 1.8x10-10). The reactions when they go into solution are: AgCl(s) ←→ Ag+(aq) + Cl-(aq) PbCl2(s)艹Pb+2(aq) + 2 Cl-(aq) a. What are the expressions for the equilibrium constants, Kop for the above reactions? b. Explain why it is possible to dissolve more lead(I)chloride in solutions in which the concentration of the silver ion is present. c. Explain what...
