Answer 1

1. Aluminum doesn't contain iron or steel so it doesn't rust.

2. Articles made of iron rust faster in coastal regions because the air contains lots of humidity (water and oxygen) which help in the formation of rust on iron.

4. It happens because when magnesium ribbons burns in presence of air it undergo oxidation reaction to form magnesium oxide. This change proceeds with the evolution of heat and light due to which we see dazzling white flame.

So sorry, I don't know the 3rd one. Please mark brainliest if you found it helpful.
