Liquid elemental iron is produced in the thermite reaction because enough heat is generated to melt the iron:
2 Al(s) + Fe2O3(s)----> Al2O3(s) + 2 Fe(l)
What mass of aluminum is needed to produce 750 grams of iron?

2 moles of Al produces 2 moles of Fe. and 750grams of Al is 750g/26gmol-1 = 28.85moles. 2Al is 2x28.85moles = 57.7moles which is equal to the mole of Fe.
with this mole, use the formula m = nMr to find the mass, where n is the mole and Mr is the molar mass of iron.
with this mole, use the formula m = nMr to find the mass, where n is the mole and Mr is the molar mass of iron.
