Question

A liquid compound of mass 18u 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 confitions , then 178 grams of gas y and 2 grams of gas z is obtained at the negative electrode . Moreover gas y supportscombustion where as gas z burns itself causing explosions
1.name x,y,z
2.what is the ratio of the mass of an element z to the mass of an element y in liquid x?
3.which law of combination is illlustrated?

Answer 1

HEY MATE YOUR ANSWER IS

If we have to find Z then it is Hydrogen

IF HELPFUL MARK ME AS BRAINLEAST PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE

Answer 2

Answer:

Explanation:

If we have to find out X then it is water as water is only liquid that is obtained from nature and all of us need it for survival then y is oxygen as electric current is passed through water and it is produced from positive electrode then Z is hydrogen because it is produced from negative electrode

b) the ratio Z and Y in liquid X will be..

Itit will form H2O where H=1×2 and O =16 it's ratio will be 2:16 which will give 1:8
