An liquid compound X of molecule mass 18...

An liquid compound X of molecule mass 18 u can be obtained from a number of natural sources. All the animals and plants need liquid X for their survival. When an electric current is passed through 200 grams of pure liquid X under suitable conditions, then `178` grams of gas Y and 22 grams of gas Z are produced. Gas Y is produced at the positive electrode whereas gas Z is obtained at the negative electrode. Moreover, gas Y supports combustion whereas gas Z burns itself causing explosions.
(a) Name (i) liquid X (ii) gas, Y and (iii) gas Z.
(b) What is the ratio of the mass of element Z to mass of element Y in the liquid X?
(c ) Which law of chemical combination is illustrated by this example ?
(d) Name two source of liquid X.
(e ) State an important use of Y in our life.
