Question

Using Stock notation, represent the following compounds:
$HAuC{l}_4,T{l}_{2}O,FeO,F{e}_2{O}_3,Cul,CuO,MnO$ and $Mn{O}_2$

Answer 1

The oxidation number of each metalic element in its compound is as follows:

$HAuC{l}_4\to Au\text{has}3$

$T{l}_{2}O\to Tl\text{has}1$

$FeO\to Fe\text{has}2$

$F{e}_2{O}_3\to Fe\text{has}3$

$CuI\to Cu\text{has}1$

$CuO\to Cu\text{has}2$

$MnO\to Mn\text{has}2$

$Mn{O}_2\to Mn\text{has}4$

$FinalAnswer:$ Therefore, these compounds may be represented as:

$HAu\left(III\right)C{l}_4,T{l}_2\left(I\right)O,Fe\left(II\right)O,F{e}_2\left(III\right)O_3,Cu\left(I\right)I,Cu\left(II\right)O,Mn\left(II\right)O,Mn\left(IV\right)O_2$
