0.019moles

Explanation:

Given parameters:

Mass of Fe₂O₃ = 1.5g

Unknown:

Number of moles of Fe produced = ?

Solution:

To solve this problem, we must work from the known to the unknown. The known specie here is the mass of Fe₂O₃.

First inspect the equation and balance it;

     2Fe₂O₃  +    3C    →    4Fe   +    3CO₂

Now find the number of moles of Fe₂O₃

Number of moles of Fe₂O₃ = \frac{mass}{molar mass}

 molar mass of Fe₂O₃ = 2(56) + 3(16) = 112 + 48  = 160g/mol

 Number of moles = \frac{1.5}{160} = 0.009375moles

 From the equation, we see that;

   2 moles of Fe₂O₃ produced 4 moles of Fe

   0.009375 moles of Fe₂O₃ will produce \frac{0.009375 x 4}{2} = 0.01875‬moles of Fe

To 2 decimal places;

     0.019moles

Evaporation is commonly used to concentrate dissolved solids in a liquid feed stream and produce pure water vapor.
Sergio [31]

Answer:

True

Explanation:

Evaporation is the process by which a substance changes its state from liquid to gas. evaporation occurs at all temperatures but it's rate increases as temperature increases.

Pure water vapour can be produced by evaporation.

As the liquids are removed, the solids present in solution becomes more concentrated.
