Can aluminium oxide be reduced using carbon
WebAluminum oxide can be reduced to aluminum metal using carbon, the other reaction product being carbon monoxide. Determine the enthalpy change when 80 g of aluminum is produced by this method. [ΔH° f (carbon monoxide) = -110.5 kJ/mol; ΔH° f (aluminum oxide) = -1669.8 kJ/mol] 2. The specific heat of water is 4.184 J/g·°C.

Web(Lead oxide + Carbon → Lead + Carbon monoxide) 3. Reduction by Aluminium (aluminotherapy) Oxides of manganese and chromium metals are reduced to metals with the help of Aluminium. The process of reduction of a metal oxide to the metal with the help of aluminium is called aluminotherapy. 3MnO 2 + 4Al → 3Mn + 2Al 2 O 3 (Manganese … WebBy assigning oxidation numbers, we can pick out the oxidation and reduction halves of the reaction. Aluminum is oxidized to Al 2 O 3 in this reaction, which means that Fe 2 O 3 must be the oxidizing agent. Conversely, Fe 2 O 3 is reduced to iron metal, which means that aluminum must be the reducing agent.
