Name the following radicals :
Cr2072
A liquid compound X of molecular 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.
- Name (i) liquid X (ii) gas Y, and (iii) gas Z.
- What is the ratio of the mass of element Z to the mass of element Y in the liquid X ?
- Which law of chemical combination is illustrated by this example ?
- Name two sources of liquid X.
- State an important use of Y in our life.
