Two examples of diatomic molecules containing atoms of the same element are N 2 and O 2 . Two examples of diatomic molecules containing atoms of different elements are CO and HCl. Two examples of polyatomic molecules containing atoms of the same element are O 3 and P 4 . Two examples of polyatomic molecules containing atoms of different elements are H 2 O and NH 3 . 54. Acids are substances that form hydrogen cations in solution. A base is a compound that produces hydroxide ions in an aqueous solution and reacts with an acid to from a salt. An oxoacid is an acid that contains hydrogen, oxygen, and at least one other element, which forms an anion by the loss of one or more protons. An oxoanion is a polyatomic ion that contains one or more oxygen atoms.

Unformatted text preview: A hydrate is a compound with a specific number of water molecules attached to it. 56. KClO : Potassium hypochlorite Ag 2 CO 3 : Silver carbonate HNO 2 : Nitrous acid KMnO 4 : Potassium permanganate CsClO 3 : Cesium chlorate KNH 4 SO 4 : Potassium ammonium sulfate FeO : Iron(II) oxide Fe 2 O 3 : Iron(III) oxide TiCl 4 : Titanium(IV) chloride NaH : Sodium hydride Li 3 N : Lithium nitride Na 2 O : Sodium oxide Na 2 O 2 : Sodium peroxide 60. The two carbon atoms are the most closely related in chemical properties because if you change the electrical charge of the atom it impacts the chemical properties greatly.
