Which of the following statement is wrong ?

Options

A. The two sulphur atoms in the thiosoulphate ions occoupy equivalent positions
B. Ice results from cooling of water whereas snow results from cooling of vapour to solid
C. Formation of ice is solidification whereas formation of snow is hoar frost
D. Ice sublimes on moon

Answer

B

Explanation

`_(16)^(35)S+SO_(3)^(2-)rarr[_(16)^(35)SSO_(3)]^(2-)overset(2H^(+))(rarr)._(16)^(35)S+H_(2)O+SO_(2)`
The tanggin technique confirms that two `S` atoms in `S_(2)O_(3)^(2-)` ions do not occupy equivalent positions.
Also, water `overset("solidification")(rarr)ice`
`ice overset(rarr)"sublimation"` vapour `overset(rarr)(Hoar f rost)` ice
ice `rarr`vapour
when external pressure is reduced on ice, `P_(ext)` at moon=`0`
