Answer 1

Answer:

Condition: Al reacts with seam. (1M)

Balanced Chemical Equation: 4Al + 6H₂O -----------> 2Al₂O₃ + 6H₂↑ (1M)

Explanation:

Aluminium doesn't react with cold or hot water. Instead, it reacts with steam to produce amphoteric aluminium oxide and evolve hydrogen gas.

The chemical reaction reaction representing the above chemical change is as below:

4Al + 6H₂O -----------> 2Al₂O₃ + 6H₂↑

Answer 2

Aluminium reacts with water due to its nature of highly negative redox potential.

• When aluminium reacts with water it gives to products one is the hydrogen gas and second one is the aluminium oxide.
• Aluminium is capable of getting easily corrosive and make the things oxidized.
• But we can use the oxidizing of the aluminum  because it has the special property that is the artificial oxidized that is called anodizing.
• This will help to prevent the aluminium oxidized.
• Anodizing is process to convert the aluminium into aluminium oxide to prevent the things.
