Question

Magnesium and copper metals are heated directly over a flame. Which of the two will burn in the air? Give equation

Answer 1

magnesium . because Mg is highly reactive than copper and react with air more readily.

Answer 2

Hey fellow,

Magnesium is a very reactive metal as compared to copper . It reacts very easily to the mild temperatures and reacts with oxygen instantly. Therefore, when copper and magnesium are heated together, magnesium being more sensitive to change, reacted with air and burn with a lush bright flame. This is also the reason that magnesium strips were used in world war.  

I hope the answer was helpful.

Thanks for asking.
