Meat is a mixture.
I would guess it would be a compound because your breath is basically water vapor and water is a compound (H2O)
It isn't a element, as an element is one atom. It would be a compound if the elements chemically combined, but if they didn't, its a misture
If I was given an unknown liquid and asked to determine if it was an element, a compound, or a mixture I would heat the unknown liquid up to see if any compounds separated from the unknown liquid. After that I would get a microscope and look to see if it is a pure element. Then I would get a Platelet separation machine and put the liquid in the machine to see if the liquid separated. Thats how I would determine if the an unknown liquid is an element, a compound, or a mixture.
I would say a mix of powdered silicon and table salt (NaCl).
This would be a mixture or a compound, you choose :D
A chocolate sundae would be considered a mixture. The ice cream alone would be a compound, but the addition of all the other components would make it a mixture. It isn't an element.
Lemonade would be classified as a mixture...this because lemonade is a mixture of water and artificial flavoring, which includes sugar. Therefore, it is a mixture.
compound
Brine is usually understood to be common salt in water. However, there are also other salt solutions that would also be classified as a brine. It is a solution and thus also a homogenous mixture.
mixture
Wood is a MIXTURE of many compounds, so your answer would be a mixture.
Depends on the type of apple juice. If it is a mixture of water and apple concentrate then it is a mixture.
Yes rice is a compound because if rice was not not a compound, but and element, it would be on the periodic table.
my best guess would be a mixture because to me it would be uniform throughout.
A mixture of oil and water is a mixture, not an element. If by substance you mean not a pure substance (element or compound), then oil and water would be a substance (that is a mixture). If you mean oil and water separately, then oil is a mixture of hydrocarbons, and water is a compound (pure substance).
A river delta would be a heterogeneous mixture of compounds and elements
I would guess it would be a compound because your breath is basically water vapor and water is a compound (H2O)
