24. About 20cm of magnesium ribbon is chopped up into 1cm lengths and placed in a crucible which is then weighed along with its lid.

The crucible is heated strongly and the lid gently raised avery few seconds.
When the lid was raised a bright glow was seen to spread through the mixture

When the reaction is over the crucible + contents + lid are all re-weighed.
A white ash remains in the crucible.

These are his results:
  • Mass of empty crucible + lid  = 51.2g
  • Mass of crucible + lid + magnesium (before heating) = 54.3g
  • Mass of crucible + lid + contents (after heating) = 54.7g
 

What evidence is there that a chemical change is taking place?
(read all options before answering) 
 
 
 
 
25. About 20cm of magnesium ribbon is chopped up into 1cm lengths and placed in a crucible which is then weighed along with its lid.

These are his results:
  • Mass of empty crucible + lid  = 51.2g
  • Mass of crucible + lid + magnesium (before heating) = 54.3g
  • Mass of crucible + lid + contents (after heating) = 54.7g
