You can determine the concentration of acids or bases in a solution by

a. the ph scale

b. a salt

c. the periodic table of elements

so to find the empirical formula you have to simplify. what is something you can take out of all three? the number three, so divide everything by three leaving you with (c2h6o). i hope this !

1. an ionic bond is an attraction between oppositely charged ions. a covalent bond is sharing of electrons between atoms.

2. a bond between two atoms

3. covalent bond

4. they have different properties because the arrangement of atoms is different.

5. mutual attraction between the nuclei and electrons in two different atoms
