Flash experiment

By Mangotsfield School

In this video we will show the reaction between magnesium and copper oxide. We will cause these to react, as a result causing a bright white flash. To set this experiment up, we suspended a tin bottle top using an iron wire mesh. We then placed a mixture of copper oxide and magnesium in powdered form and of equal proportion into the bowl. We then lit a busen burner and heated the contents. This triggered the flash.

 

Question

What causes the magnesium to react more rapidly?

Answers

(a) The iron in the bottle cap
(b) The powdered form of the magnesium
(c) The oxygen in the copper
(d) Global warming
