A non-metal 'X' is lustrous, insoluble in water but soluble in alcohol, when it reacts with another metallic element 'Y' , it forms a substance'Z' which are used in cloud seeding or artificial rain. Identify X, Y and Z. What are theadvantages of artificial rain? Is there anysubstances other than Z than Z that can be used for artificial rain? If so,what are they?

1.	A non-metal 'X' is lustrous, insoluble in water but soluble in alcohol, when it reacts with another metallic element 'Y' , it forms a substance'Z' which are used in cloud seeding or artificial rain. Identify X, Y and Z. What are theadvantages of artificial rain? Is there anysubstances other than Z than Z that can be used for artificial rain? If so,what are they?
Answer» Solution :A lustrous non-metal which is soluble inalcohol is iodine. It REACTS with the metallic element silver to form silver iodide which is used in cloud seeding or artificial rain. So 'X' is iodine, 'Y' is iodine, 'Y' is silver, Z is silver iodide. Artificial rain is very MUCH useful inagriculture at the time of DROUGHT or WATER scarcity. Silver nitrate and dry ice (solid carbon dioxide) can also be used for artificial rain.
