56 g because iron has a greater mass amount and will therefore lead to being the mass of the final product.
90 g because the end products must be equal to the orignal amount of reactants due to the law of conservation of matter.
80 g because matter cannot be created nor destroyed. The amount of matter on the reactants must be equal to that of the products.
32 g because when combined you will end up with the difference of the reactants for your final product amount. This is shown by the law of conservation of mass.

80 g because matter cannot be created nor destroyed. The amount of matter in the reactants must be equal to that in the products according to the Law of Conservation of Matter.
