C o I 2 CoIX2: cobalt(II) iodide Correct name B a C l 2 BaClX2: barium dichloride Correct name C s 2 O CsX2O: cesium oxide Choose... R b 2 S RbX2S: rubidium sulfite Correct name S r B r 2 SrBrX2: strontium(II) bromide Incorrect name

Respuesta :

Answer: [tex]CoI_2[/tex] : cobalt (II) iodide : correct

[tex]BaCl_2[/tex] : barium di chloride : incorrect

[tex]Cs_2O[/tex] : cesium oxide: correct

[tex]Rb_2S[/tex] : rubidium sulphite : incorrect

[tex]SrBr_2[/tex] : strontium (II) bromide : correct

Explanation:

The nomenclature of ionic compounds is given by:

1. Positive is written first followed by the oxidation state of metal in roman numerals in parenthesis.

2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

Hence, the name of [tex]CoI_2[/tex] is cobalt (II) iodide, [tex]BaCl_2[/tex] is barium (II) chloride, [tex]Cs_2O[/tex] is cesium oxide, [tex]Rb_2S[/tex] is rubidium sulphide and [tex]SrBr_2[/tex] is strontium (II) bromide.
