Answer:
A compound is a substance that has two or more chemical elements whose atoms are bonded together. These atoms are chemically bonded in specific ways and in detailed proportions, and the substances cannot be readily separated through simple physical means.
hope this helped :)
Answer:
When a reduction reaction and an Oxidation reaction takes place due to passing of current through water the molecules of water split into the compounds. Where it is made up of hydrogen in its state of gas and also Oxygen in its state of gas this method is most vastly is known as electrolysis.
In this process a certain direct current is passed from inside water. This direct current value can be near about 1.23 voltages the reaction that happens inside is given below.
2 Water---> Oxygen + 4 hydrogen ions + 4 Electrons
2 Hydrogen ions + 2 electrons ----> hydrogen gas
<span>The standard temperature and pressure is 273.15 K and 1 atm. We use the
ideal gas equation to solve this problem to find for the amount of gas in moles.
PV = nRT
n = PV / RT = 5100 mmHg x 20.1 L / </span>62.364<span> x 302.15
n = 5.44 mol
At STP,
V = nRT / P = </span><span>5.44 mol x</span> 62.364 x 273.15 / 760
V = 121.94 L<span>

Carbon electrodes are changed frequently in electrolysis as the carbon in the carbon electrodes burns to give out Carbon-di-oxide.
Carbon electrodes are used in electrolysis to facilitate the transfer of electrons between the anode and the cathode. The carbon electrode is usually in the form of a rod or plate and is electrically connected to the anode.
The carbon electrode may also be used to help reduce the overall resistance of the electrolytic cell.
Carbon electrodes are used in electrolysis because they are chemically inert and have a high electrical conductivity.
However, carbon electrodes must be changed frequently because they become corroded and lose their electrical conductivity over time.
This is because carbon burns out in the Carbon electrodes to give out Carbon-di-oxide. That is why the carbon anodes should be changed frequently.
