Answer:

239.6 mg is the  theoretical yield of tribromoanisole.

Explanation:

C_6H_5-OCH_3+3Br_2\rightarrow C_6H_2Br_3-OCH_3+3HBr

Mass of anisole C_6H_5-OCH_3 = 75 mg = 0.075 g

1 mg = 0.001 g

Moles of anisole = \frac{0.075 g}{108 g/mol}=0.0006944 mol

According to reaction, 1 mole anisole gives 1 mole of tribromoanisole.

Then 0.0006944 mole of anisole will give:

\frac{1}{1}\times 0.0006944 mol=0.0006944 mol of tribromoanisole

Mass of 0.0006944 mole of tribromoanisole:

0.0006944 mol × 345 g/mol = 0.2396 g = 239.6 mg

239.6 mg is the  theoretical yield of tribromoanisole.

How is freeze dried ice cream made
ollegr [7]
Freeze drying<span> (or lyophilization) removes water from the ice cream by lowering the </span>air pressure<span> to a point where ice sublimates from a </span>solid<span> to a </span>gas<span>. The ice cream is placed in a </span>vacuum chamber<span> and frozen until the water </span>crystallizes<span>. The air pressure is lowered, creating a partial vacuum, forcing air out of the chamber; next heat is applied, </span>sublimating<span> the ice; finally a freezing coil traps the vaporized water. This process continues for hours, resulting in a freeze-dried ice cream slice. </span>
