A gas that cannot be collected over water is
A gas that cannot be collected over water is
Updated On: Jun 14, 2022
- $N_2$
- $O_2$
- $SO_2$
- $PH_2$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
$SO_2$ cannot be collected over water because it reacts with
water forming $H_2SO_3.$
$SO_2+H_2O \longrightarrow H_2SO_3$
water forming $H_2SO_3.$
$SO_2+H_2O \longrightarrow H_2SO_3$

A conducting loop PQR, in the form of an equilateral triangle of the same height 𝐿, is placed in the x-y plane with its vertex P at x = 0 in the orientation shown in the figure. At 𝑡 = 0, the loop starts entering the region of the magnetic field with a uniform velocity 𝑣 along the +x-direction. The plane of the loop and its orientation remain unchanged throughout its motion.

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
