Naturally occurring chlorine is composed of two isotopes: 75.76% Cl-35 (mass 34.9688 amu) and 24.24% Cl-37 (mass 36.9659 amu). Naturally occurring oxygen iscomposed of three isotopes: 99.757% O-16 (mass 15.9949 amu); 0.038% O-17 (mass 16.9991 amu); and 0.205% O-18 (mass 17.9991 amu). The compound dichloromonoxide iscomposed of two chlorine atoms and one oxygen atom bonded together to form the molecule.
Homework Answers
We have naturally occurring isotopes of chlorine are 75.76% Cl-35 (mass 34.9688 amu) and 24.26% Cl-37 (mass 36.9659 amu); isotopes of oxygen are 99.757% O-16 (mass 15.9949 amu), 0.038% O-17 (mass 16.9991 amu), and 0.205%O-18(mass 17.9991 amu) are respectively.
Dichloromonoxide is composed of two chlorine atoms and one oxygen atom bonded together to form CI2O molecule.
