Question

Hello people ~

Answer 1

Answer:

C

H²O is dissociated in water into H³O+ (hydronium ions) and OH- (hydroxide) given by;

2H²O <-----> H³O+ + OH-

If you notice initially we have 4 hydrogen atoms and 2 oxygen atoms. And similarly after the reaction we have 4 hydrogen atoms and 2 oxygen atoms.

Ratio of H to O is 4:2

or 2:1

This is very intuitive as we have 2 hydrogen atoms and 1 oxygen atom in a water molecule.

Answer 2

Answer:

Explanation:

The volume of Hydrogen and Oxygen molecules are not the same but assuming that they are, the ratio in water which is H2O would be

(c) 2:1
