Can someone please help me on the second one? I have no idea what to do.
Aleks [24]

The reaction will produce 12.1 g Ag₂S.

<em>Balanced equation</em> = 2Ag + S ⟶ Ag₂S

<em>Mass of Ag₂S</em> = 10.5 g Ag × (1 mol Ag/107.87 g Ag) × (1 mol Ag₂S/2 mol Ag)

× (247.80 g Ag₂S/1 mol Ag₂S) = 12.1 g Ag₂S

Andre45 [30]

Answer:

Here's what I get.

Explanation:

At the end of the reaction you will have a solution of the alcohol in THF.

The microdistillation procedure will vary, depending on the specific apparatus you are using, but here is a typical procedure.

  • Transfer the solution to a conical vial.
  • Add a boiling stone.
  • Attach a Hickman head (shown below) and condenser.
  • Place the assembly in in the appropriate hole of an aluminium block on top of a hotplate stirrer.
  • Begin stirring and heating at a low level so the THF (bp 63 °C) can distill slowly.
  • Use a Pasteur pipet to withdraw the THF as needed.
  • When all the THF has been removed, raise the temperature of the Al block and distill the alcohol (bp 143 °C).
