Inorganic compounds

Question 1

are substances that contain carbon atoms, usually bonded with hydrogen, oxygen, and sometimes nitrogen. Most living things (like plants, animals, and humans) are made up of organic compounds. Examples include sugars, fats, and proteins.

Answer 1

Organic compounds

Question 2

are substances that do not contain carbon (with a few exceptions like carbon dioxide). They are often found in non-living things like rocks, water, and minerals. Examples include table salt (NaCl), water (H₂O), and metals like iron.

Answer 2
