    The reaction between aluminum powder and iron oxide is the famous thermite agent.

    Thermite is a mixture of aluminum powder and ferric oxide powder in proportion to form a pink mixture, ignited with an ignition agent when used, and the reaction is carried out violently to obtain alumina and elemental iron, and the iron formed is a molten high-temperature liquid, which can be directly used for field welding. The reaction equation is as follows:

    It depends on the amount of aluminum!

    If aluminum is insufficient.

    2al+3fe2o3=al2o3+6feo, if aluminum is sufficient.

    2al+fe2o3=al2o3+2fe

    Object residue after the reaction:

    al2o3+feo+fe2o3

    al2o3+feo

    al2o3+fe+feo

    al2o3+fe

    al2o3+fe+al

    Five scenarios.

    The chemical equation for the reaction of aluminum with iron oxide is Fe2O3+2Al=2Fe+Al2O3.

    Aluminum is a silvery-white active metal, pure aluminum combines with oxygen in the air to form alumina at room temperature, and the alumina layer will hinder the reaction between oxygen and aluminum, shielding the aluminum inside from being further oxidized. Iron oxide is a reddish-brown powder, easily soluble in strong acid, medium strong acid, the reaction needs to be carried out under high temperature conditions, aluminum and iron oxide reaction is commonly known as "thermite reaction".

I'm a chemistry teacher in my first year of high school, so what's the use of giving you all the ion equations? The key to science is to understand, just take a good look at the steps of writing the ion equation in the book and digest it. Just pay attention to what should be dismantled and what can't be dismantled, and the ion equation is not too difficult to learn.

Step 1: Write the chemical equation for the reaction.

For example: cuso4+bacl2=cucl2+baso4 Step 2: Write the substances that are easy to ionize with water and easily in ionic form (only strong electrolytes can be written), and insoluble substances or substances that are difficult to ionize and gases are still expressed by chemical formulas (including weak electrolytes and non-electrolytes, which cannot be written as ionic equations). >>>More
