Is banana a pure substance?

Question

Help, PLEASE. ;;)

Answer 1

Yes.  Everything with a definite chemical formula is a pure substance.  It has the chemical formula BaNa2.

Answer 2

Actually

no it is not

Answer 3

Absolutely not, a banana contains many different sugars, esters (fruity smelling chemicals), minerals and different substances. If it was pure, it would have a chemical formula, like pure water does (H2O) or pure carbon dioxide (CO2).

Hope this helps :)

Answer 4

Only if the can it came in is unopened.

It might be a pure substance but it is not an element.

It can be fractionated into chemical coumpounds that can be broken down farther into the chemical elements.

To say something is a pure substance only means it has no contaminants in it.

If your banana had a bit of buldada mixed with it then it would not be pure.

Answer 5

Cute, Pisgahchemist,

Bananas, like most food items, contain maybe hundreds of different chemicals, and are therefore, not pure substances.
