Z is efflorescent
Y and Z are efflorescent
Y and Z are deliquescent
Y and Z are hygroscopic
Y is deliquescent
Correct answer is C
A deliquescent compound is a compound that, on exposure to the atmosphere, tends to absorb moisture from the atmosphere in large quantities. Hence, Y and Z are DELIQUESCENT.
an increase in temperature favours the forword reaction
an increase in pressure favours the backward reaction
