Question

Zeolites:

विकल्प

• are microporous aluminosilicates.

• have general formula M_x/n [(AlO₂)_x (SiO₂)_y] · mH₂O.

• have a pore size between 260-740 pm.

• all of the above

Answer 1

All of the above

Explanation:

Zeolites are microporous aluminosilicates with the general formula M_x/n [(AlO₂)_x (SiO₂)_y] · mH₂O, where (M) is a metal cation. They have pore sizes between 260-740 pm, which contribute to their shape-selective catalytic properties.
