1.	In a chemistry laboratory, aresearch scholar while conducting an experiment , observed at a certain step, that a yellow coloured gas (X) was released and it has been found to bepoisonous. This was later made to react with a highly reactive metal (Y). A new compound (Z)wasformed which is used for preservation of fish, meat and pickles. The professor asked him toidentify X, Y and Z.
Answer» SOLUTION :A greenish YELLOW POISONOUS gas 'X' is CHLORINE. Onreaction with a metal, sodium (highly REACTIVE metals) chlorine gas forms sodium chloride which is used for preservation of fish, meats and pickles. So 'Z' is sodium chloride, 'X' is chlorine gas and Y is sodium metal.
