Yes, rusting is a redox reaction. It involves the transfer of electrons between iron and oxygen, resulting in the formation of iron oxide (rust).
Yes, rusting in a car involves a redox reaction where iron in the metal reacts with oxygen in the air to form iron oxide (rust). In this reaction, iron is oxidized from its elemental state to iron oxide, while oxygen is reduced to form water.
There is a transfer of electrons during both reactions and that is what a redox reaction is.
A redox (oxidation-reduction) reaction involves the transfer of electrons between reactants. For example, the reaction between iron (Fe) and oxygen (O2) to form iron oxide (Fe2O3) is a redox reaction. In this reaction, iron atoms lose electrons (oxidation) while oxygen atoms gain electrons (reduction).
The reaction you are referring to is a displacement reaction in which aluminum replaces iron in iron(III) oxide to form aluminum oxide and iron. The balanced equation for the reaction is: 2Al + Fe2O3 -> Al2O3 + 2Fe
Methane, CH4, burns in oxygen gas to form water and carbon dioxide. What is the correct balanced chemical equation for this reaction?

It will form a mixture of the two compounds.
Rusting of iron is a redox reaction where iron reacts with oxygen and water to form iron oxide (rust). It is not a combination reaction since it involves the transfer of electrons between iron and oxygen.
When you mix aluminum and oxygen, you get aluminum oxide. If you mix iron with aluminum oxide, the aluminum will react with the iron oxide, forming a thermite reaction that produces molten iron and aluminum oxide slag.
Rust is a redox-reaction, meaning it is a reation where electrons are exchanged. Water would be the oxidation-agent and iron and aluminum the reduction-agents. As can be seen on the table of standard cell potensials, aliminium is a strong reduction-agent and water is too weak to induce oxidation. Iron, however, is not as strong, and can undergo oxidation.
A copper II ion can be replaced by other metal ions that have a higher reactivity in a redox reaction. Common examples include zinc, iron, and aluminum ions.
