The concepts of chemical bonds and valence provide a means of determining which molecules might form and, of these possibilities, which are likely to be stable and which are likely to be unstable. For instance, from the smoke in this picture we take two small molecules that contain only a single chemical bond to form hydrogen chloride (H-Cl). Describe the concept of chemical bonds and valence. Include in your discussion why firefighters should be concerned with CO.
