Which statement best relates an empirical formula with a molecular formula? . a. they are always different for the same compound.. b. subscripts of empirical formulas can be reduced.. c. molecular formulas can be determined from empirical formulas.. d. they both show the actual ratio of elements for a compound.

empirical formula is the simplest ratio of whole numbers of components making up a compound

molecular formula is the actual composition of components making up a compound

to analyse each statement

A.They are always different for the same compound. -

the empirical formula in some instances can be the same as the molecular formula. therefore this statement is incorrect.

B. Subscripts of empirical formulas can be reduced

empirical formula gives the simplest ratios and the subscripts cannnot be further simplified therefore this is incorrect

C. Molecular formulas can be determined from empirical formulas

using the empirical formula, the molecular formula can be determined. therefore its correct.

D. They both show the actual ratio of elements for a compound

only the molecular formula gives the actual ratio of elements whereas the empirical formula gives the simplest ratio of elements. this statement is incorrect

the correct statement is C.

it is called acid bonding

i think its 5049.

i hope this !
