Chemical Rections

Our first Year 10 Chemical Reactions
1. Magnesium reacting with oxygen:

Method: We held a strip of magnesium metal in the hottest part of a bunsen burner flame till it caught fire. We didn't look directly at the reaction because (safety reason)
Observations:
1. The magnesium metal was a grey, shiny and flexible.
2. The magnesium burned with a very bright white light.
3. After it burned it was a white powder.


The word equation is: Iron+ Sulphur = Iron sulfide

The balanced chemical equation is: Fe + S = FeS

2. Iron filings reacting with sulphur:

Method: We mixed equal amounts of iron filings and sulphur then used a magnet wrapped in paper to separate them. We mixed them again and added the mixture to a test tube and heated strongly.
Observations:
1. The iron filings were dark, grey and powerish
2. The sulphur was neon, yellow/ green powder
3, When we heated the tube it let off a smell of rotten eggs
4. After the reaction a clump of black/ grey stuff
