Cannon Reaction (Reaction Between Hydrogen And Chlorine Gas)

Reaction between hydrogen and chlorine gas is very explosive, but to react they need light source, in this experiment we can use the magnesium that burned.
Raw material:
1. Chlorine gas
2. Hydrogen gas
3. Magnesium ribbon

Apparatus:
1. Cannon from iron pipe
2. Bunsen
3. Rubber cover
4. Test tube

Workflow:
1. Closed test tube by rubber cover and then enter into cannon
2. Burn magnesium ribbon and then enter into cannon
3. Look at video this reaction

The reaction is:
                                            light
          H2 (g)    +     Cl2 (g)  --------->      2HCl (g)
