Question

Assertion : Water obtained by every source contains hydrogen and oxygen in the ratio of 1:8 by mass.
Reason : On electrolysis of H2O ,volume of hydrogen obtained is double than that of oxygen.
Please answer this fast and correct, if spammed will be reported also first correct answer will be marked brainliest....

Answer 1

Answer:

Both ASSERTION and REASON are correct. But REASON is not the correct explanation for ASSERTION.

Explanation:

As by mass in H2O, H2 weighs 2amu and O weighs 16amu. This gives the ratio 1:8. But, while hydrolysis, H2 gas and O2 gas are released so their ratio turns out to be 1:8 but as Hydrogen has 2 atoms and Oxygen has only 1 atom in a water molecule, their VOLUME RATIO tends to be 1:2.

Answer 2

Answer:

Both a and r are true but r is notnthe correct explaination of a.
