Baking soda contains the base/alkali sodium bicarbonate NaH(CO3). The vinegar contains a mixture of acids with all have the chemical component COOH. When these two components are mixed together, they will react to form chemicals of lower energy (a ball placed on a slope will roll down). The COOH reacts with HCO3 to produce CO2 and H2O.
