478. C 



480. CaOs, HO+SO 3 =HOSO 3 +CO 2 +CO. 



490. Zn-{-SO3+HO 2 =ZnO, SO 3 +H. 



492. 3Fe+4HO=Fe 3 O4+4H. 



496. H+O=HO. 



501. Na+HO=NaO+H. 



519. H+C1=HC1. 



521. HO,SOa+NaCl=NaO, SOs+HCl. 



530. SiO 3 +3HF=3HO+SiF 3 . 



537. N+3H=NH 3 . 



539. CaO+NH 4 Cl=HO+CaCl+NH 3 . 



543. NH 3 +HC1=NH4C1. 



546. KO+3HO+2P=KO,PO 3 +PH 3 .

The other elements not mentioned in the text are glucinum, 

 cadmium, cerium, colnmbium or tantalum, didymium, erbi- 

 um, indium, lanthanum, molybdenum, niobium, norium, 

 osmium, palladium, pelopium, rhodinm, ruthenium, seleni- 

 um. tellurium, terbium, thorium, titanium, tungsten or wol- 

 framium, vanadium, ytrium, and zirconium. With the ex- 

 ception of selenium and tellurium, which are analogous in 

 their properties to sulphur, they may be classed with the 

 metals. They are of rare occurrence, and may be regarded 

 as sustaining the same relation to the other elements as do 

 the asteroids and satellites to the more important members 

 of the solar system. 



646. Zn+PbO, A=ZnO, A+Pb.
