Answer:
- C6H12O6 is not an empirical formula because it can be simplified to CH2O.
- CaCO3 is an empirical formula as well as molecular formula because it has been simplified up to the smallest subscript per atom.
- NaMnO4 is an empirical formula as well as molecular formula because it has been simplified up to the smallest subscript per atom.
- Ba3(PO4)2 is an empirical formula as well as molecular formula because it has been simplified up to the smallest subscript per atom.
- K2C2O4 is not an empirical formula because it can be simplified to KCO2.
Explanation:
Hello!
In this case, since the empirical formulas are referred to those formulas that have been simplified up to the smallest whole number for each subscript per atom, we can see that:
- C6H12O6 is not an empirical formula because it can be simplified to CH2O.
- CaCO3 is an empirical formula as well as molecular formula because it has been simplified up to the smallest subscript per atom.
- NaMnO4 is an empirical formula as well as molecular formula because it has been simplified up to the smallest subscript per atom.
- Ba3(PO4)2 is an empirical formula as well as molecular formula because it has been simplified up to the smallest subscript per atom.
- K2C2O4 is not an empirical formula because it can be simplified to KCO2.
Best regards!
