Answers:
i) The baking powder consists of sodium bicarbonate (NaHCO3) and small amount of mild tartaric acid [COOH-CH(OH)-CH(OH)-COOH].
ii) Baking powder is made up of baking soda, and a dry acid (usually cream of tartar, sometimes sodium aluminum sulfate). When the liquid is added to the recipe, it interacts with the two, causing the them to react and form bubbles of carbon dioxide gas.
iii) Chemical equation = NaCl+H2O+CO2+NH3= NH4Cl+NaHCO3
