Answer:
we will use universal gas law
Explanation:
First, convert torr to atm
Molar mass = 61.9
Note: I converted Celsius to kelvin and mL to L
Answer:
Explanation:
N₂ (g ) + 4H⁺( aq ) + 4e⁻ = N₂H₄ ( aq )
H⁺ ion comes from acidic medium . 4 positive charge on proton is balanced by 4 electron to make left hand side neutral because right hand side is neutral .
I would typically assume it is error in the state (s, l, g, aq) but depending on what reaction i couldn't say for sure
A) Anode - hydrogen gas
Cathode-oxygen gas
B) Hydrogen gas - The gas burns with a pop sound
Oxygen gas - The gas rekindles a glowing splint
C) The volume of gas produced at the cathode is 23
<h3>What is electrolysis?</h3>
Electrolysis is the process by which electric current is passed through a substance to effect a chemical change.
The electrolysis of water produces two volumes of hydrogen at the anode and one volume of oxygen at the cathode.
The hydrogen gas burns with a pop sound. It is easily identified by this test. Also, oxygen is known to rekindle a glowing splint and this is a commonly used test for oxygen gas.
Since the ratio of hydrogen produced at the anode to oxygen produced at the cathode is 2:1 by volume; then when 23 of oxygen is produced at the cathode, 46 of hydrogen is produced at the anode.
