Question

When water decomposes (2H2O) what two elements are produced?

a. Oxygen and Hydrogen in the form of gases.

b. Oxygen in the form of a gas and hydrogen in liquid form

c. oxygen in the form of a liquid and Hydrogen in the form of gas

d. oxygen and Hydrogen in a liquid form​

Answer 1

Answer:

(a) Oxygen and Hydrogen in the form of gases.

Answer 2

a

the chemical reaction of this decomposition:

2H2O ---------> 2H2 + O2

this decomposition is called electrolysis and will takes place only when water is containing some electrolyte (for example: salt) and electricity will be used. as this can create high temperature, this will take place in high pressure to balance temperature. because of that pressure, it will generate both oxygen and hydrogen gases.
