This activity is about burning a magnesium ribbon . If you burn a magnesium ribbon you can identify that there will be a white flame produced and a white product (MgO) . This is a activity to explain that a chemical reaction takes place when there is a chance in state , temperature,colour and evolution of gas . Here, the identification property is white dazzling flame . Equation :- 2Mg + O2 = 2MgO Note :- 1) scratch the magnesium ribbon with sand paper before burning because there is a layer of MgO ( magnesium oxide ) over it which prevents further reaction . 2) wear a sunglass before you do this experiment to not affect your eyes while burning .
