The following reaction was carried out:

2-methyl-2-butanol was mixed with 12M HCl and distilled to give 2-chloro-2-methylbutane

1. Why is this reaction carried out a room temperature instead of at an elevated temperature? Would yield of desired product increase or decreased at elevated room temperatures? Why?

2. Illustrate the mechanism for the desired reaction; use electron-pushing format and provide the name of the mechanism.

3. What products would you predict if the starting material (the alcohol) were reacted with NaCl + concentrated H3PO4?

4. Is there another hygroscopic acid that would work to perform the reaction in #3?

Would someone be able to help me answer the post lab questions for the following experiment?

Thank you for your time in advance!

Calcium carbonate is hygroscopic, meaning it will absorb moisture from the atmosphere. A researcher needs to ensure that the reagent is pure so she places 5.00 g of the calcium carbonate in a 25.0 mL sealed vial and heats this in an oven at 300K for an hour. When heated, solid calcium carbonate can decompose to solid calcium oxide and carbon dioxide gas. If 0.00500% of the solid reagent decomposed, what will the pressure (atm) of carbon dioxide gas in the vial be?

Please help!!!
