2. A mixture of 60 wt% benzene, 35% toluene, and 5% naphthalene is being distilled. The distillate product should be 99.5 wt% benzene. Also, 99% of benzene fed should be recovered in the distillate, Determine/calculate: a. Distillate and bottom product flow rates (D and B) per 1 kg of feed b. compositions of distillate and bottom product c. fraction of toluene fed that is recovered in the bottom product

(a)  Distillate (D) = 0.597 kg

    Bottom product (B) = 0.403 kg

(b) Compositions of distillate  product:

     Benzene = 0.995

     Toluene = 0.05

   Compositions of bottom product:

    Benzene = 0.0149

    Naphthalene = 0.1241

    Toluene = 0.8610

(c) Fraction of toluene fed that is recovered in the bottom product = 99.14%

Explanation:

See the attached file for the calculation

im pretty sure its b

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
