Also there was one question I had no idea on, the question about the word to describe the water on the earth and in the atmosphere or something. Anyone willing to tell me what it was?
It was hydrosphere :) That was a really confusing question

I swear when I did the corrosion experiment, the nails in water were rustier than the nails in the salt water. & my teacher didn't even say anything when I handed in the report of it. Stupid contamination 8(

I guessed neutralisation too. I think it was precipitate though.
