Yes, the combustion of magnesium, or anything else for that matter, represents a chemical change. For magnesium, the combustion reaction results in the loss of magnesium and the production of magnesium oxide. Clearly a chemical change.

Is melting solder a physical or chemical change and why?
chemical because you are able to turn it into a solid again adn melt it again and agian and it can be changed to origanal state. :)

When plastic is made is it a physical or chemical change and why?
it is a chemical change and i think maybe it is because you use heat to melt it and metal to shape it.
Why does magnesium metal melt at higher temperature than sodium metal?
Due to one unit more nuclear charge and two binding electrons for Magnesium atom.
When salt melt is a chemical change or a physical change?
It's a physical change.
CAN YOU melt metal with a magnifying glass?
Yes, all substances have a melting point. However, special procedures may need to be followed to melt magnesium as it is a flammable substance.
When a ice cube melt is that a chemical property?
no that is a physical property change, not a chemical property.
Is something that burns easily a physical or chemical change?
If you burn something it is a chemical change, however if you melt of boil it, it is a physical change.
Is melt lead chemical or physical change?
Physical. Melting is always a physical change.
Is the melting of ice a chemical change?
no it is not it is a physical change because you add heat energy to melt it

It's physical
When does magnesium melt at?
650 degree celsius
What metal can get hot enough to glow but not melt?
all metal can melt
is water freezing into ice a chemical change?
No , it is not a chemical change because chemical changes are irreversible i.e. original substance cannot be recovered but in this change we can easily melt the ice and back to its normal state.
