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 gases x and y into simpler particles. which statement is best supported by this evidence?

The best option that support the evidence of this electrolysis is D.

Explanation:The electrolysis of water molecule start from the separation of cations( Hydrogen ions) to the cathode(which is negatively charged) and anions(Oxygen ions) to the anode (which is positively charged) especially in a Hoffman cell, when an electric current is passed through the water electrolyte

The Oxygen ions at the anode will loose their electrons to the anode, and become oxidized, thus combine with another Oxygen atom to form a diatomic molecule, which will be released at this same anode.

Likewise, the hydrogen ions at the cathode will gain electrons from this electrode and become reduced, this combine with other hydrogen atom at the cathode to form a diatomic molecule, which is the hydrogen molecule released at the cathode. These products are all molecules, but are not compounds since they are made up of one element each. Because of this, they cannot be further broken down into simpler form using ordinary method like electrolysis. So they are elements. Option D.

lol idk man i guess u gotta ask bill nye the science guy

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
