Question

sno₂ spell out the full name of the compound. part b hgbr₂ spell out the full name of the compound. part c cocl₂ spell out the full name of the compound.

Explanation:

Step1: Identify metal and non - metal

In $SnO_2$, $Sn$ (tin) is a metal and $O$ (oxygen) is a non - metal. Tin can have multiple oxidation states. Oxygen has an oxidation state of - 2. In $SnO_2$, the oxidation state of $Sn$ is + 4.

Step2: Name the compound

The name is tin(IV) oxide.

Step3: For $HgBr_2$

$Hg$ (mercury) is a metal and $Br$ (bromine) is a non - metal. Mercury can have oxidation states of + 1 and + 2. In $HgBr_2$, the oxidation state of $Hg$ is + 2. The name is mercury(II) bromide.

Step4: For $CoCl_2$

$Co$ (cobalt) is a metal and $Cl$ (chlorine) is a non - metal. Cobalt can have multiple oxidation states. Chlorine has an oxidation state of - 1. In $CoCl_2$, the oxidation state of $Co$ is + 2. The name is cobalt(II) chloride.

Answer:

Part A: tin(IV) oxide
Part B: mercury(II) bromide
Part C: cobalt(II) chloride
