Chemical Nomenclature Quiz

IF7 is Iodine heptafluoride, where I is the chemical symbol for Iodine (not Iron, which is Fe). The prefix hepta- indicates seven fluorine atoms. Option D has a typo (heptofluoride instead of heptafluoride).

BCl3 is Boron trichloride, where B is Boron and Cl is chlorine. The prefix tri- indicates three chlorine atoms. Options A, B, and C are incorrect - boron trioxide is B2O3, and the other names are not valid chemical names.

Na2CO3 is Sodium carbonate, commonly called soda ash or washing soda. The prefix 'tri-' would indicate three carbon atoms, which is incorrect - carbonate (CO3) is a polyatomic ion containing one carbon atom.

Co(NO3)2 is Cobalt(II) nitrate - Co is Cobalt (not Carbon), NO3 is the nitrate ion, and the Roman numeral II indicates the +2 oxidation state. Options A, C, and D are incorrect chemical names or misinterpret the symbols.

SnS2 is Tin(IV) sulfide - Sn is Tin (not Zinc), and the +4 oxidation state balances with two sulfide ions (S2-). Tin(II) sulfide would be SnS, and options C and D incorrectly identify the element as Zinc and use sulfate instead of sulfide.

Al2(SO4)3 is Aluminum sulfate - Al is Aluminum (not Potassium), and SO4 is the sulfate ion. The formula shows 2 aluminum ions balancing 3 sulfate ions. Options B and D are incorrect chemical names, and option A misidentifies the metal.

PbSO3 is Lead(II) sulfite - Pb is Lead, SO3 is the sulfite ion (not sulfate), and the +2 charge balances with the sulfite ion. Options A, B, and C are incorrect - option C contains a typo (sulpahte).

Fe(OH)2 is Ferrous hydroxide, where iron is in the +2 oxidation state (Fe2+). The term 'ferrous' specifically refers to Fe2+, while 'ferric' refers to Fe3+.

(NH4)3PO4 is Ammonium phosphate, formed from three ammonium ions (NH4+) and one phosphate ion (PO4 3-). It's commonly used as fertilizer.
