2024年6月6日 · Aluminum will not rust like Iron, but it does corrode. 4Al + 3O2 ---> 2Al2O3 Aluminum + oxygen gas ---> Aluminum oxide

2024年12月20日 · he following equation is balanced 4Al 3O2 -- 2Al2O3 is not a balanced equation.on the reactants side we haev 4 atoms of Al and we have 24 atoms of oxygen.

2024年6月6日 · There are 4 atoms of aluminum in 2Al2O3. Each formula unit of Al2O3 contains 2 atoms of aluminum. Therefore, when we have 2 formula units (2Al2O3), we have a total of 4 aluminum atoms.

2024年5月21日 · Aluminium + Oxygen ----> Aluminium oxideBalanced equation:4 Al + 3 O2 ----> 2 Al2O3

2024年5月27日 · This is a chemical reaction where aluminum (Al) reacts with oxygen (O2) to form aluminum oxide (Al2O3). The balanced chemical equation for this reaction is 4Al + 3O2 → 2Al2O3.
