Identify the correct statement from t he following .

Options

A. `O_(3),SO_(2)` molecules have different shapes
B. The molecules formula of pyrosulphuric acid is`H_(2)S_(2)O_(0)`
C. In the presence of moisture ,`SO_(2)` acts as an oxidising agent
D. `V_(2)O_(5)` acts as catalyst in constant process

Answer

D

Explanation

`O_(3)` and `SO_(2)` both have same shape
(b) Pyrousulphuric acid is `H_(2) S_(2) O _(7)`
(c ) In the presence of moisture `SO_(2)` act as reducing agent .`H_(2)O + SO_(2) rarr SO_(3)`
(d) `V_(2) 0_(5)` act as catalyst in contact process.
`2SO_(3) overset(v_(2)O)rarr H_(2) S_(2)O_(7), i,e(H_(2)SO_(4).SO_(3))`
