Question

Select all that apply.

Why are mixtures (such as sugar in water) not given chemical formulas?


Their elements are unknown.
No chemical bonding took place.
Mixtures do not contain compounds.
The elements or compounds in the mixtures have no definite proportions.

Answer 1

No chemical bonding take place.
And the elements or compounds in the mixtures have no definite proportions.

Answer 2

I would go with B.  The elements of sugar and water have been known for a long time, so A is irrelevant. Mixtures can contain compounds- most of the time mixtures are composed of compounds mixed together, so C is false as well. Chemical formulas are designed to handle different proportions- that's why they have the numbers before the chemical name, such as 2H2O. B is your best bet for this one, as a mixture is more than one chemical combined but not bonded.
