An intimate mixture of ferric oxide and aluminium is used as solid fuel in rockets. Calculate the fuel value per `cm^(3)` of the mixture.
Heats of formation and densities are as follows:
`H_(f(AI_(2)O_(3)))^(Theta)=-399kcal mol^(-1),H_(f(Fe_(2)O_(3)))^(Theta)=-199kcal mol^(-1)`
Density of `Fe_(2)O_(3)=4.0 g cm^(-3)`, Density of `AI = 2.0 g cm^(-3)`

An intimate mixture of ferric oxide and aluminium is used as solid fuel in rockets. Calculate the fuel value per cm^(3) of the mixture. Heats of formation and densities are as follows: H_(f(Al_(2)O_(3)))=-399kcal" "mol^(-1),H_(f(Fe_(2)O_(3)))=-199kcal" "mol^(-1) ltbr. Density of Fe_(2)O_(3)=5.2g//cm^(3)," Density of "Al=2.7g//cm^(3)

An intimate mixture of ferric oxide, (Fe_(2)O_(3)) and aluminium, (Al) is used in solid fuel rockets. Calculate the fuel value per gram and fuel value per cc of the mixture. Heats of formation and densities are as follows : Delta H_(f)^(0)(Al_(2)O_(3))= 399 " kcal mol"^(-1), Delta H_(f)^(0)(Fe_(2)O_(3))= 199 " kcal mol"^(-1) , Density of Fe_(2)O_(3)= 5.2 g// c c , Density of Al= 2.7g// c c .

An intimate mixture of Fe_(2)O_(3) and Al_(2)O_(3) is used in solid furl for rockets. Calculates the furl value per gram and fuel value per cm^(3) of the mixture. DeltaH(Fe_(2)O_(3))=1669.4kJ*mol^(-1) DeltaH(Al_(2)O_(3))=832.6kJ*mol^(-1) .

An intimate mixture of Fe_(2)O_(3) and Ai is used in solid rocket fuel. Calculate the fuel value per gram and per ml of mixture. DeltaH_(Al_(2)O_(3)) = 399.0 kcal, DeltaH_(Fe_(2)O_(3))=199.0 kcal, density of Fe_(2)O_(3) and Al are 5.2 g/ml and 2.7 g/ml respectively.

An intimate mixture of Fe_(2)O_(3) and Al is used in solid fuel rocket. DeltaH of Al_(2)O_(3) and Fe_(2)O_(3) are 399kcal and 199kcal respectively. Calculate the fuel value in kcal g^(-1) of mixture.

In above question7, if the density of Fe_(2)O_(3) and Al are 5.2g//mL and 2.7g//mL respectively. Calculate the fuel value in kcal mL^(-1) of mixture.

AI is costilier than Fe but AI is sacrificed to convert Fe_(2)O_(3) into Fe . Why this change is possible. Name this process : {:(Delta G_(f(Fe_(2)O_(3)))^(@) =-"742.2 kJ/mole"),(Delta G_(f(AI_(2)O_(3)))^(@)=-"1582 kJ/mole"):}
