What is the empirical formula of a compound composed of 3.25% hydrogen (H), 19.36% carbon (C), and 77.39% oxygen (O) by mass?
blsea [12.9K]
CH2O3

C=19.36\12    =  1.61
H=3.25\1.008 =3.22
O=77.39\16=4.83

then dived the moles with the smallest mole 

C=1.61\1.61=1
H=3.22\1.61=2
O=4.83\1.61=3

E.F
CH2O3

Which substance contains bonds that involved the transfer of electrons from one atom to another?
Ivanshal [37]
The transfer of electrons is an ionic bond, therefore, we need to determine which substance includes an ionic bond.

CO2, is a covalent bond, which is the sharing of electrons, not transfer.
KBr, is an ionic bond, because (k) loses an electron to bromine. 

So, our final answer is:-   <span>(3) KBr</span>
