1.	X ana Y are gases at room temperature. X is less rective and is used to preserve food matrial, while 'Y' is required for combustion. Metal 'M' gets corroded when it combines with 'Y' in the presence of 'Z'. An atom of 'M' possesses 14 electrons in the second last shell and N is the shell.Identify X, Y, Z and M.
Answer» SOLUTION :14 electrons in M shell and 2 electrons in N shell corresponds to metal 'Fe'. X is nitrogen which is FILLED in air tight food packets to prevent oxidation and Y is oxygen which is required for combusion. In presence of oxygen and water vapour (Z) metal IRON (M) GETS ruted to form a compound that is `Fe_(2)O_(3).XH_(2)O.` X = nitrogen Y = oxygen, Z = water vapour and M = Fe.
