Weekends are really good for relaxing and enjoying instead of writing heavy posts. Don't you think?
(Credit: here)
To add on to the lazy Sunday, I am creating a science challenge to soften the Saturdays also. Interested in the contest? Why not check out if you have the knowledge to win the prize.
What is Aluminium Oxide (the chemical formula in the image above)?
Known by many names including alumina, aoxide or alundum, so what is it?
A - It is the protective layer formed on Aluminium metal.
B - This is what causes Aluminium metal to corrode.
C - It is chemical formula of the Ore from which Aluminium is extracted.
D - None of the above
How to play?
- UPVOTE this post
- Just write a comment with either A B C or D with no other words as the result is done through automation.
- There are no other rules!

Science Challenge # 3 - Do you know your hair?Answer is A. It is kind of a layer that if damaged mechanically, repairs itself later.
but is it protective? =)
What do you think layers do ?
well, first of all, they ruin the material itself as they make it thinner, right?
Yup.. But afterwards, it turn into layer.
and does it really protective? Protective from what? Oxygen only?
Air, Scratches ! :D
