Question

Help pls i don’t know how chemistry works, i got suspended and don’t know how any of this works cause i’m not even getting taught

Answer 1

The stoichiometry calculation reveals that 4.233 moles of
`Fe_2(SO_4)_3` are formed when 12.7 moles of
`SO_3` are reacted with
`Fe_2O_3` according to the balanced equation provided.

Stoichiometry Calculation for the Formation of
`Fe_2(SO_4)_3`

To solve the provided chemical reaction problem, we must understand stoichiometry, which is the part of chemistry that involves calculating the amounts of reactants and products in a chemical reaction. Given the balanced chemical equation for the formation of
`Fe_2(SO_4)_3` from
`Fe_2O_3`and
`SO_3`:

`Fe_2O_3` + 3
`SO_3` →
`Fe_2(SO_4)_3`

We can see that one mole of
`Fe_2O_3` reacts with three moles of
`SO_3` to produce one mole of
`Fe_2(SO_4)_3`. Therefore, when 12.7 moles of
`SO_3` react:

• 1 mole of
  `Fe_2O_3` reacts with 3 moles of
  `SO_3`
• Therefore, 12.7 moles of
  `SO_3` will react with 12.7 / 3 = 4.233 moles of
  `Fe_2O_3`
• Since the reaction produces one mole of
  `Fe_2(SO_4)_3` for every mole of
  `Fe_2O_3`, 4.233 moles of
  `Fe_2(SO_4)_3` will be formed

4.233 moles of
`Fe_2(SO_4)_3` are formed when 12.7 moles of
`SO_3` are reacted.
