Hi, I'm having trouble with answering these organic chemistry lab questions. Please give full answers in your own words. Thanks in advance

1. Which of the following solvents: acetone, diethly ether, dichloromethane, pentane, THF, form upper layers or lower layers and which are miscible or immiscible with water during an extraction?

2. What is the consequence of only cooling the recrystallization solution to room temperature instead of 0 degrees celsius.

3. What is the consequence of only cooling the recrysyallization solution to quickly?

4. A mixture of carboxylic acid and a phenol can often be seperated by extracting with aqueous sodium bicarbonate and a suitable organic solvent. What difference in cehmical properties of the carboxylic acid and the phenol make this seperation possible?

5. What is the practical advatnage of using dichloromethane over diethly ether for extracting organic compounds from an aqueous solution using a seperatory funnel? What are the advantages and disadvantages of using diethly ether as an extraction solvent?

Draw the Lewis structure for the I−3.

A student dilutes a solution of 0.100 mol of H3PO4 and 0.150 mol of NaOH with water to a volume of 1.00 L but then realizes that the "distilled water" used was in fact dilute hydrochloric acid.

(A) If the pH of the final solution is 6.62, what are the concentrations of H3PO4, H2PO^−4, and HPO^2−4?

(B) How many moles of HCl were inadvertently added to the original solution?

Many Thanks

(a) Derive a general expression for the energy difference between any two neighboring rotational state (i.e, the difference in energy between the L abd L+L states). (b) How does the energy difference change as L increases? (c) How does the energy difference change if the radius, r, of the rotating particle increases?

some of the hydrated salt spatter out the crucible because of a too rapid heating process. will the reported percent water in the hydrated salt be reported too high, too low, or unaffected? explain.

A typical relaxed sarcomere is about 2.3 μm in length and contracts to about 2 μm in length. Within the sarcomere, the thin filaments are about 1 μm long and the thick filaments are about 1.5 μm long.

Calculate the overlap of thick and thin filaments in the relaxed and contracted sarcomere.
