What is the empirical formula for the following compounds?

A) #Na_2O_2#
B) #C_8H_6O_4#
C) #C_12H_12N_2O_3#
D) #C_4H_6Cl_2#

Answer 1

A. #NaO#
B. #C_4H_3O_2#
C. #C_12H_12N_2O_3#
D. #C_2H_3Cl#

An empirical formula is the lowest ratio of the elements in a compound.

So for each of the compounds above, the GCF of the elements was used to divide the number of the atoms of each element in the formulas of the compounds.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
