#### Solution Preview

a) UO2<+2>

<br>Let x be the Oxidation Number (ON) of U. Then x - 2*2 = +2 which gives x = +6

<br>Therefore, ON of U = +6

<br>ON of O = -2

<br>

<br>b) As2O3

<br>Let x be the ON of As. Then 2x - 3*2 = 0 which gives x = +3

<br>Therefore, ON of As = +3

<br>ON of O = -2

<br>

<br>c) NaBiO3

<br>Let x be the ON ...
