you can't produce ketchup without even mixing an ingredients on it. So, i therefore suggest that a ketchup is a MIXTURE :)
It is a complex mixture.
Ketchup? Well, it is simply a mixture as the ingredients are not chemically bonded together as they are in a substance
Ketchup is not considered to be a neutral substance. Ketchup is considered to be an acidic substance with a low pH.
Ketchup is a mechanical mixture because the tomatoes are pureed.
Yes because ketchup is a mixture in which the constituents don't appear separately.
As a whole you could call it a substance, but it is made up of many different atoms. A mixture, however; would describe it more accuratly since a mixture is more than one substance not chemically bound to eachother, i.e. the ketchup or the bun.
No, it is a mixture.
Ketchup is a mixture.
Ketchup is not on the periodic table of elements therefore it is not an element. Ketchup does not have a single chemical name like H20 (water) or H2SO4 (Sulphuric Acid), therefore is not a compound. Ketchup consists mainly of a mixture of vinegar and tomatoes, which aren't elements or compounds themselves, therefore ketchup is a mixture of a lot of molecules.
I suppose that ketchup must be considered nonhomogeneous because frequently two phases are distinct.
Ketchup is a mixture of many ingredients both ionic and covalent
An element - substance - NOT a mixture.
a mixture is not a substance
