supposethat 0.450 moles of f3203 are reacted with an excess of aluminum and 43.6 g fe are obtained what is the % yield
The percent yield of iron is, 86.5 %
Given,
Moles of iron(III)oxide = 0.450 mole
Mass of iron = Actual yield of Fe = 43.6 g
First we have to calculate the moles of iron.
The balanced chemical reaction is,
2Al+ 2 Fe₂O₃ --> 2Fe + Al₂O₃
From the balanced reaction we conclude that
As, 1 mole of Fe₂O₃ react to give 2 mole of Fe
So, 0.450 mole of Fe₂O₃ react to give 2/1 x 0.450 = 0.9 moles of Fe
Now we have to calculate the mass of Fe.
Mass of Fe = Moles of Fe x Molar mass of Fe
Mass of Fe = (0.9mole) x (56g/mole)= 50.4g
Therefore, the mass iron produces, 50.4 g
Now we have to calculate the percent yield of Fe.
% yield of Fe = (Actual yield of Fe/ Theoretical yield of Fe) x 100%
= 43.6g/50.6g x 100% = 86.5%
Therefore, the percent yield of Fe is, 86.5 %
The question whose answer is given:
If 0.450 moles of iron III oxide (Fe2O3) are allowed to react with an excess of aluminum (Al) and 43.6 grams of iron (Fe) is produced, what is the percent yield of iron?

The percent yield of the magnesium oxide in this context is 87.3%.
What is the percentage yield?We know that the percentage yield has to do with the amount of the product that we get from the reaction expressed as a percentage. We know that the combination of the magnesium and the oxygen molecule would lead to the formation of the magnesium oxide.
The oxygen and the magnesium are the reactants while the magnesium oxide is the product.
Mass of magnesium = Mass of magnesium and crucible - mass of crucible
= 38.06 g - 35.67 g
= 2.39 g
Number of moles of Mg = 2.39 g/24 g/mol
= 0.0996 moles
Mass of magnesium oxide = Mass of magnesium oxide and crucible - mass of crucible
= 39.15 g - 35.67 g
= 3.48 g
Number of moles of the magnesium oxide = 3.48 g/40 g/mol
= 0.087 moles
From the reaction;
2 moles of Mg produces 2 moles of MgO
Hence the theoretical yield of the Mgo is 0.0996 moles
Percent yield = Actual yield/ Theoretical yield * 100/1

If you think about the water molecules as liquid water freezes, would you say they get closer together, further apart, or stay at about the same distance from one another?
Answer:Water is unusual because its molecules move further apart when it freezes. The molecules of just about every other substance move closer together when they freeze.
Explanation:
During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds.
