Magnesium is an element, so it's a pure substance.
Tea is not a pure substance as it is a mixture of milk and the tea solution, the tea solution containing water, tea leaf particles and sugar particles. Without milk, the tea is still not a pure substance.
Butter is a mixture.
Homogenized milk is a mechanical mixture because it is made up of two or more substances that are physically combined but not chemically bonded.
They are a mixture of small toasted flakes of corn, flavored with salt, sugar and malt.

Milk is a complex mixture.

Magnesium is an element, so it's a pure substance.
Yogurt is not a pure substance because its a mixture of different elements/molecules (Cow milk and sugar and more...) from the Periodic Table
Chocolate pudding would be considered a pure substance.
Tea is not a pure substance as it is a mixture of milk and the tea solution, the tea solution containing water, tea leaf particles and sugar particles. Without milk, the tea is still not a pure substance.
Buttermilk is not a pure substance; it is a mixture. It typically consists of water, fats, proteins, and various other components, including vitamins and minerals, derived from the fermentation of milk. The composition can vary depending on the method of production and the source of the milk. Therefore, it does not meet the criteria of a pure substance, which has a uniform and definite composition.
Cow milk is considered a mixture, not a pure substance. It contains water, fats, proteins, lactose, vitamins, and minerals, all of which are combined but not chemically bonded. The components can vary in concentration and can be separated through physical means, such as centrifugation. Therefore, milk does not have a fixed composition, characteristic of pure substances.
In science, purity refers to the extent to which a substance is free from impurities or contaminants. A pure substance consists of only one type of molecule, atom, or ion. Purity is often determined through techniques such as chromatography or spectroscopy.
