Laughing Gas (novel) and darling of all American mothers. Joey is also going to have a tooth out, but Joey is going to be operated on by B.K. Burwash, Zizzbaum's rival—they have a common waiting-room—exactly at the same time as Reggie. Presently reporters storm the dentist's practice to take photos of Joey and interview him. Both Reggie and Joey get laughing gas as anaesthetic. When Reggie regains consciousness he finds himself spoken to by B.K. Burwash, and also in the latter's chair. He concludes that there has been a switch in the fourth dimension: Joey's and his souls have changed bodies. Before he
Chemical formula arrangement of bonds in a simple chemical substance, though it does not necessarily specify isomers or complex structures. For example, ethane consists of two carbon atoms single-bonded to each other, with each carbon atom having three hydrogen atoms bonded to it. Its chemical formula can be rendered as CHCH. In ethylene there is a double bond between the carbon atoms (and thus each carbon only has two hydrogens), therefore the chemical formula may be written: CHCH, and the fact that there is a double bond between the carbons is implicit because carbon has a valence of four. However, a more
