Answer:

6.65 grams of Fe₂O₃ are required to produce 4.65g Fe.

Explanation:

The balanced reaction is:

Fe₂O₃ + 3 CO → 2 Fe + 3 CO₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

  • Fe₂O₃: 1 mole
  • CO: 3 moles
  • Fe: 2 moles
  • CO₂: 3 moles

The molar mass of each compound is:

  • Fe₂O₃: 159.7 g/mole
  • CO: 28 g/mol
  • Fe: 55.85 g/mole
  • CO₂: 44 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

  • Fe₂O₃: 1 mole* 159.7 g/mole= 159.7 grams
  • CO: 3 moles* 28 g/mol= 84 grams
  • Fe: 2 moles* 55.85 g/mole= 111.7 grams
  • CO₂: 3 moles* 44 g/mole= 132 grams

Then you can apply the following rule of three: if by stoichiometry 111.7 grams of Fe are produced from 159.7 grams of Fe₂O₃, 4.65 grams of Fe are produced from how much mass of Fe₂O₃?

mass of Fe_{2} O_{3} =\frac{4.65 grams of Fe*159.7 grams  of Fe_{2} O_{3}}{111.7grams of Fe}

mass of Fe₂O₃= 6.65 grams

<u><em>6.65 grams of Fe₂O₃ are required to produce 4.65g Fe.</em></u>

Which of the following shows 3x + 15 + 6x – 7 + y in simplest terms?
prisoha [69]

Answer:

9x+y+8

Explanation:

We know this because you add 3x and 6x to get 9x

then we only have one y so put y by itself then subtract 15 and y which gets us 8
