Kelly ran electricity though a sample of water using electrolysis. the water changed into two gases, x and y. it was not possible to break down the gasses x and y into simpler particles. which statement is best supported by this evidence. a. the gas y is a water vapor.
b. water is an element.
c. the gases x and y are compounds.
d. the gases x and y are elements

d.the gases x and y are elements

Explanation:

Since it is impossible to further break down the gases produced during this electrolytic process, we can conclude that the gases x and y are elements.

An element is a distinct substance that cannot be split up into simpler substances. Such substances are made up of only one kind of atom.

It is impossible through chemical reactions split an element into simpler units.
