X, Y and Z are three substance, On passage of electricity through X, two substances A and B are formed, Y is a liquid which on evaporation generates C as a residue and D was vaporized. Z could not be split up into any simpler substances further. A is found to be a good conductor of heat and electricity while B was found to be a gas. it is possible to split C and D into simpler substances chemically. what do you infer regarding the nature of these substances with respect to composition?

1.	X, Y and Z are three substance, On passage of electricity through X, two substances A and B are formed, Y is a liquid which on evaporation generates C as a residue and D was vaporized. Z could not be split up into any simpler substances further. A is found to be a good conductor of heat and electricity while B was found to be a gas. it is possible to split C and D into simpler substances chemically. what do you infer regarding the nature of these substances with respect to composition?
Answer» Solution :X is a compound A and B as X could be split up into A and B by the passage of ELECTRICITY Y should be a mixture of C and D as they could be obtained by physcial method like evaporation. A should be a METAL and B should be a non-metal. C and D are compounds as they cold be split up into simpler SUBSTANCES by HEATING Z is an element as it could not be split up into simpler substances.
