Baking powder is a mixture of sodium hydrogen carbonate and tartaric acid carbon dioxide produced during this reaction can cause bread or cake to rise and makes them soft and spongy. When we use baking powder tartaric acid neutralizes.

The type of chemical reaction that will take place is photochemical decomposition. This is a type of decomposition reaction which involves the use of light energy for decomposition.

Within the lungs, we get balloon-like structures which are called alveoli. It can be found the passage divides into smaller and smaller tubes which finally terminate as alveoli.
