Reaction of non-metals with oxygen

The video tutorial demonstrates an experiment where coal is burned in an oxygen jar, producing carbon dioxide. This gas is then dissolved in water to form carbonic acid, which turns violet litmus solution red. The experiment illustrates how non-metals react with oxygen to form non-metal oxides, using carbon as an example.
