Why is it important to balance the redox equation for the electrolysis of water?.
77julia77 [94]

Electrolysis is a process, which allows us to break down a chemical compound into its elements, completing the balance by adjusting the number of atoms on both sides of the reaction is important because the number of electrons given up during oxidation must be the same as the number of electrons gained during the reduction.

<h3>What is electrolysis of water?</h3>

It is a process of oxidation and reduction of one or more elements that, through the induction of electric current, breaks down the water molecule (H2O), thus producing gaseous hydrogen and oxygen.

Oxidation and reduction processes occur simultaneously and never in isolation, which is why they are called redox reactions.

Therefore, we can conclude that electrolysis is a process where electrical energy will change to chemical energy where it is important that the number of electrons given up during oxidation is the same as the number of electrons gained during reduction.

Let's find the temperature when the pressure is equal to zero.
slega [8]

The significance of the point where the pressure drops to zero is that at that point the gases would completely show ideal behavior.

<h3>What is the gas law?</h3>

The gas laws can be used to describe the behavior of the ideal gases. It is pertinent to note that the ideal gas law can strictly be applied to gases that are at a high temperature and low pressure.

We can be able to find the  temperature when the pressure is equal to zero either be the use of the equation line or by experiment. In that case, we would be able to obtain the point at which the pressure drops to zero.

The significance of the point where the pressure drops to zero is that at that point the gases would completely show ideal behavior.
