learning task 4. identify the given materials if they homogeneous or heterogeneous. Give reason for your answer 1.Milk 2.Hydrogen 3.Sand mixed with water 4.Carbon dioxide 5.Milk and oat
because Oat is solid and milk is liquid so we can seperate them?Answer:
1.Milk, for example, appears to be homogeneous, but when examined under a microscope, it clearly consists of tiny globules of fat and protein dispersed in water. The components of heterogeneous mixtures can usually be separated by simple means.
2.sand and salt: heterogeneous; saltwater: homogeneous; pure water: compound; tossed salad: heterogeneous; hydrogen: element; unfiltered air: homogeneous; an apple: heterogeneous; granite: heterogeneous; iron: element; iron with rust: heterogeneous; nitric acid: compound; wood: heterogeneous.
3.heterogeneous mixture
Correct answer: A mixture of sand and water is the best example of heterogeneous mixture. A mixture in which the composition is not uniform throughout the mixture then it is said to be a heterogeneous mixture.
4.Is carbon dioxide an element a compound a heterogeneous mixture or a homogeneous mixture?
