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 a different connectivity from other molecules that can be formed using the same atoms in the same proportions (isomers). The formula (CH)CH implies a central carbon atom connected to one hydrogen atom and three CH groups. The same number of atoms of each element (10 hydrogens and 4 carbons, or CH) may be used to make a straight chain molecule, "n"-butane: CHCHCHCH. In any given chemical compound, the elements always combine in the same proportion with each other. This is the law of constant composition. The law of constant composition says that, in any particular chemical compound, all samples of
