[NAC (Nanoparticle Assembled Capsule)] The purple dye used to demonstrate encapsulation in this experiment is a mixture. The components of this colour are Carmoisine (Red) and Indigo Carmine (Blue). The yellow colour Curcumin could not be encapsulated when tried. Why?

Please be specific in terms of molecular structure and its chemical properties.

Suppose a 500. mL flash is filled with 1.1 mol of CO, 1.6 mol of NO and 0.90 mol of CO2. The following reaction becomes possible: NO2(g)+CO(g)=NO(g)+CO2(g).

the equilibrium constant K for this reaction is 0.209 at the temperature of the flask. Calculate the equilibrium molarity of NO. Round to the nearest two decimals.

1. a) Show the balanced half reactions and the total balanced reaction for the following redox reaction in acidic solution.

RuO4 + H2SeO3 → Ru3+ + SeO42-

b) Comment on whether you expect this reaction to be spontaneous. Show all of your work.b

2 (a) Use the Lattimer diagram for chlorine in basic conditions to determine the potential for reduction of ClO4- to Cl2 .

(b) Write a balanced equation for this half reaction

When tert-butanol is placed in the presence of excess equimolar amounts of chloride and bromide ions in aqueous acid experimental data indicates 45% tert-butyl chloride and 55% tert-butyl bromide is obtained. On the other hand, when n-butanol is placed in the presence of excess equimolar amounts of chloride and bromide ions in aqueous acid experimental data indicates 16% of n-butyl chloride and 84% n-butyl bromide is obtained. Now when n-butanol is placed in the presence of excess equimolar amounts of chloride ions and bromide ions in acid dimethyl sulfoxide the experimental data provides an 84% n-butyl chloride and 16% n-butyl bromide as the outcome.

1.) write balanced chemical equations for all three reactions (hint: account for mole ratios!).

2.) draw complete mechanisms for all three reactions.

3.) calculate the theoretical yield for the chlorides and bromides if each reaction was started with 5.55ml of the corresponding alcohol, using an aqueous acid media.

Sample: tert
Theoretical g of chloride
Theoretical g of bromide

Sample: n-
Theoretical g of chloride
Theoretical g of bromide

Writing and balancing the equations is what is really throwing me off

what are the functional groups in organic chemistry?

please list the must know ones in a bond-like template.

Experiment - Claisen Condensation Reactions:

In this experiment, we performed a Claisen condensation reaction of ethyl phenylacetate using potassium tert-butoxide to form ethyl 3-oxo-2,4-diphenylbutanoate and ethanol without using a solvent. This allowed us to reduce waste, have reagents that have a relatively low toxicity level, and made the reaction much more convenient.

Question 2: If this reaction were run in a solution (as opposed to solvent-free) it would require several hours of refluxing and provide a much smaller yield. Why is this the case?

I cannot seem to find an answer to this question. The only thing that I can find is that the reaction is reversible when a solvent is used (which I'm assuming means that the reaction is not reversible when there is no solvent). If this is correct, why is the reaction reversible when a solvent is used, and not reversible when a solvent is not used?

A source for the answer would be appreciated if possible.

Thank you for the help in advance!
