25835 Which of the following is not an ore of lead

1 Galena

2 Anglesite

3 Calamine

4 Cerrusite

Explanation:

(c) Galena $(P b S)$ , Anglesite $(P b S O_{4}),$ Calamine $(Z n C O_{3})$ , Cerrussite $(P b C O_{3})$

25837 An example of an oxide ore is

1 Bauxite

2 Malachite

3 Zinc blende

4 Felspar

Explanation:

Bauxite is $A l_{2} O_{3} \cdot 2 H_{2} O$
Malachite is $C u C O_{3} \cdot C u (O H)_{2}$
Zinc Blende is $Z n S$
Galena is $P b S$
Oxide ore among the given is Bauxite.
Hence, Option " $A$ " is the correct answer.
