A mixture of ferric oxide(Fe2O3) and Al is used as a solid rocket fuel...
1. Balanced Reaction:
The balanced chemical equation representing the reaction of ferric oxide (Fe2O3) and aluminum (Al) to form aluminum oxide (Al2O3) and iron (Fe) is as follows:

2Al + Fe2O3 → Al2O3 + 2Fe

2. Ratio of Masses:
To determine the ratio of masses of Fe2O3 and Al that will result in maximum energy per unit of mass, we need to calculate the molar masses of the compounds involved.

The molar mass of Fe2O3 = (2 x molar mass of Fe) + (3 x molar mass of O)
= (2 x 55.845 g/mol) + (3 x 16.00 g/mol)
= 159.69 g/mol

The molar mass of Al = 26.98 g/mol

Now, let's assume the ratio of masses of Fe2O3 and Al to be x : y. Therefore, we can write the equation:

(x mol Fe2O3) / (y mol Al) = (molar mass of Fe2O3) / (molar mass of Al)

Substituting the values, we have:

(x mol * 159.69 g/mol) / (y mol * 26.98 g/mol) = 1

Simplifying the equation, we get:

(x / y) = (26.98 / 159.69)

Therefore, the ratio of masses of Fe2O3 and Al that will result in maximum energy per unit of mass is approximately 1 : 5.92.

3. Energy Released:
To calculate the energy released when 16 kg of Fe2O3 reacts with 2.7 kg of Al, we need to convert the masses into moles.

Moles of Fe2O3 = (mass of Fe2O3) / (molar mass of Fe2O3)
= (16000 g) / (159.69 g/mol)
= 100.10 mol

Moles of Al = (mass of Al) / (molar mass of Al)
= (2700 g) / (26.98 g/mol)
= 100.15 mol

From the balanced equation, we can see that 2 moles of Al react with 1 mole of Fe2O3 to release 200 units of energy. Therefore, the energy released when 100.10 mol of Fe2O3 reacts with 100.15 mol of Al can be calculated using the ratio:

Energy released = (100.10 mol Fe2O3) * (200 units/mol) = 20,020 units

Therefore, if 16 kg of Fe2O3 reacts with 2.7 kg of Al, the energy released will be 20,020 units.
