Is a cheeseburger pure substance or mixture?

Answer 1

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.

Answer 2

A cheeseburger is a mixture because it is made up of multiple ingredients combined together, such as bread, meat, cheese, and condiments. Each ingredient retains its own properties and can be separated from the others.

Answer 3

a

because it has lettuce and cheese and all that stuff.
