The elements present in baking soda are -a)Sodium, carbon and oxygenb)...
Elements present in baking soda:
- Sodium (Na): Sodium is a chemical element with the symbol Na. It is a highly reactive metal that is essential for various biological processes.
- Carbon (C): Carbon is a chemical element with the symbol C. It is a nonmetallic element that is the basis of organic chemistry and is present in all living organisms.
- Hydrogen (H): Hydrogen is a chemical element with the symbol H. It is the lightest and most abundant element in the universe and is present in various compounds.
- Oxygen (O): Oxygen is a chemical element with the symbol O. It is a highly reactive nonmetal that is essential for combustion and respiration.
Explanation:
Baking soda, also known as sodium bicarbonate (NaHCO3), is a compound that consists of the elements sodium, carbon, hydrogen, and oxygen. The chemical formula of baking soda indicates the presence of these elements.
