* Compounds are formed when two or more elements chemically combine in a fixed ratio. For example, water (H₂O) is a compound because it's made of hydrogen and oxygen atoms bonded together.
* Cereal is a mixture of different ingredients, primarily grains like wheat, oats, or rice. It might also include sugar, flavorings, and other additives. These ingredients are not chemically bonded together.
Think of it this way: You can separate the components of cereal (like the grains and sugar) by physical means, like picking them out. You can't do that with a compound like water; you need a chemical reaction to separate hydrogen and oxygen.
Therefore, cereal is a mixture rather than a compound.
