Science Experiment

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:

The balanced chemical equation is:

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, 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.


The word equation for the reaction is: Iron + Sulphur -> Iron Sulfide 
iron sulfate.The balanced chemical equation is: Fe + S -> FeS
