. KMnO4 oxidizes ethyl benzene to benzoic acid. If this reaction generally results in a 40 % experimental yield, how many grams
lyudmila [28]

Answer:

530.835 g

Explanation:

First we convert 244 g of benzoic acid (C₇H₆O₂) to moles, using its molar mass:

  • 244 g benzoic acid ÷ 122.12 g/mol = 2.00 moles benzoic acid

Theoretically,<em> one mol of ethyl benzene would produce one mol of benzoic acid</em>. But the experimental yield tells us that one mol of ethyl benzene will produce only 0.4 moles of benzoic acid.

With the above information in mind we convert 2.00 moles of benzoic acid into moles of ethyl benzene:

  • 2.00 moles benzoic acid * \frac{1molEthylBenzene}{0.4molBenzoicAcid} = 5.00 moles ethyl benzene

Finally we <u>convert moles of ethyl benzene </u>(C₈H₁₀)<u> into grams</u>, using its <em>molar mass</em>:

  • 5.00 moles ethyl benzene * 106.167 g/mol = 530.835 g ethyl benzene

Identify the correct type of heat transfer for A, B, and C in the picture. Using the picture, cite evidence for your choices.
tatiyna

The correct type of heat transfer for A, B, and C are conduction, convection and radiation respectively.

<h3>What is heat transfer?</h3>

Heat transfer is a process in which amount of heat will be transferred from one object to any other object by various means.

  • In type A, heat is transferred through conduction process as in this transfer takes place due to direct contact of particles.
  • In type B, heat is transferred through the convection process as in that process transfer of heat takes place through the medium.
  • In type C, heat transfer done by the radiation as in that transfer through empty space.

Hence at A, B and C heat transfer done through conduction, convection and radiation respectively.
