Web< 1. In a reaction known as the thermite reaction, iron (III) oxide reacts with aluminum to give molten iron. Fe2O3 (s) + 2 Al (s) → 2 Fe (l) + Al2O3 (s) What amount of Al, in moles, is needed for complete reaction with 3.0 mol of Fe₂O3? What mass of Fe, in grams, can be produced? Answer 2. WebWhen a metal reacts with oxygen, it forms metal oxide. The nature of the oxide formed depends on the reactivity of the metal.Explanation:Reactivity of metals: Metals differ in their ability to react with oxygen, depending on their position in the reactivity series.Reactivity series of metals: The reactivity series of metals is a list of metals arranged in the order of …

WebThe aluminium foil appears unable to displace copper from copper(II) sulfate solution. Now aluminium is more reactive because it displaces copper. Aluminium + copper(II) sulfate → copper + aluminium sulfate; Scratches on the surface of the oxide layer allow chloride ions to react with aluminium, this effects the cohesiveness of the oxide layer. WebFor every mole of aluminum that reacts with iron oxide, 851 kJ of heat is released. If 0.79 moles of aluminum is consumed in the reaction, the heat released is equal to -851.5*0.79 = -672.685 kJ. WebAug 22, 2024 · "Aluminium powder and iron (III) oxide react with each other in a "thermite" reaction, which releases a lot of heat. This reaction has been used (for example) in building railways, which requires molten iron. The chemical equation regarding this reaction is 2 Al(s) + Fe2O3(s) --> 2 Fe(l) + Al2O3(s). ... military pay rmc calculator
