Which of the following statements are correct?
(I) When water is decomposed volume ratio of to is 2:1, but the mass ratio is 1:8.
(II) Water is a polar compound
(III) Water is good conductor of electricity.
Select the correct answer given below

Options

A. (I) and (II)
B. (I) and (III)
C. (II) and (III)
D. All of these

Answer

D

Explanation

When water decomposed volume ratio of `H_(2)`to `O_(2)` In 2:1, but the mass ratio of `H_(2)` to `O_(2)` is 2: 1, but the mass ratio is 1:8, water is a polar compound, its dipole moment is 1.85 D, but water is bad conductor of electricity.
