PROCESING FYQ
1)Place some in a glass baking soda.
2) Add some vinegar to the glass
3) Place a lighted match on top of the glass. In a short time the mach will go out.
When the vinager is mixed with sodium bicarbonate the chemical reaction generates carbon dioxide. we can say that this carbon dioxide drowns out the match, because it prevents the oxygen of the air from feeding the combustion reaction.
