Is bread a compound or mixture?
Explanation: Very few samples of matter consist of pure substances; instead, most are mixtures, which are combinations of two or more pure substances in variable proportions in which the individual substances retain their identity. Air, tap water, milk, blue cheese, bread, and dirt are all mixtures.
Is Raisin Bran a compound or element?
The composition of Raisin Bran varies from scoop to scoop and is a mixture of raisin and flake “elements” that can be easily separated.

Is spoiled milk a homogeneous mixture?
Explanation: Heterogeneous mixtures are non-uniform solutions that can be separated into two (or more) individual substances by physical means (homogeneous mixtures cannot be). With milk, you have white particulates that give a non-uniform solution, so it is heterogeneous.
Why is the milk white?
However, milk also contains protein, fat and vitamins. One of the main types of proteins in milk are caseins, which join in small clusters with calcium and phosphate to form tiny particles called micelles. This causes milk to reflect all light wavelengths and absorb none, making it appear white.
