How do ions become molecules at the electrodes?
Ions can become molecules at the electrodes through electrodeposition or electrochemical reduction or oxidation processes. When a specific voltage is applied across the electrodes, ions gain or lose electrons, leading to the formation of neutral molecules. This can occur when ions react with other species present at the electrodes or in the electrolyte.
Why do the positive electrodes have to be replaced on a regular basis?
Positive electrodes, or cathodes, in batteries degrade over time due to chemical reactions and the buildup of byproducts during discharge and recharge cycles. This degradation can lead to reduced capacity, efficiency, and overall battery performance. Regular replacement is necessary to maintain optimal functionality and ensure the longevity of the battery system. Additionally, worn electrodes can cause safety issues if they fail or become unstable.
How does the parts of a cell interact to produce a current?
In a electrochemical cell or a battery there are two electrodes and an electrolyte. Chemical reaction occurs between the electrodes and the electrolyte which causes one of the electrodes to be positively charged and the next one to be negatively charged. The differences between the two electrodes creates voltage. When the battery is now connected to a circuit it makes a current.
How do chemical reaction charge electrodes?
Chemical reactions occur between the electrolyte and the electrodes in an electrochemical cell. These reactions cause one electrode to become negatively charged and the other electrode to become positively charged.
Why do the positive electrodes have to he replaced frequently?
Positive electrodes in batteries often need to be replaced frequently due to degradation caused by chemical reactions during charge and discharge cycles. Over time, materials can become unstable, leading to reduced capacity and efficiency. Additionally, the buildup of byproducts and loss of active material can hinder performance. Frequent replacement helps maintain optimal battery function and longevity.
Why do you think it is advantageous to use inert electrodes in the electrolysis processes?
If the electrodes are not inert, then they are going to become part of the chemical reaction, rather than just being conduits for electricity, and if they become part of the chemical reaction, they are going to get used up, and you will wind up with no electrodes.
Why do car batteries go bad?
Car batteries contain cells. The cells are attached to each other to create the battery. Each cell contains electrodes or things that look something like small plates. The cells also contain sulphuric acid. When the battery produces electricity, the chemicals in the plates dissolve in the sulphuric acid. When the battery recharges, the chemicals go back into the plates. The chemicals do not go back perfectly. Eventually, some drop to the bottom of the cell and can not be used. When too many drop off, the cell may develop a short circuit and become useless or the plate may become so small it can not produce enough electricity. They fact that you live on a New York street with a pot hole every three feet and it jars your battery to pieces also ruins your battery!

How does lightning become electricity?
Lightning doesn't become electricity. Lightning already is electricity.
Why do rechargable batteries stop working properly?
A battery produces electricity because electrons flow from one reactant in the battery's chemical reaction to another reactant. However, once one of the reactants is completely used up, the chemical reaction stops, thus also stopping the flow of electricity. Now, how does a battery recharge? Well, the details of this are a bit too complicated to get into, but I can provide a abbreviated explanation. A battery charger produces an electrical force that actually causes the battery's chemical reaction to reverse. Thus, when a battery is dead, it has all the products and no reactants. A battery charger will force those products to react with each other and reform the reactants. Once that happens, the battery is ready to go again. This doesn't work for all batteries, however. That's why many batteries are not rechargeable. Hope this helps!
What is the difference between a battery and a paperclip?
A battery has electricity in it already, with a paper clip, however, you need to get an electric shock going to make that become electric, because it is metal, but only for a split second.
Is there electric in Africa?
Yes. Many African nations have become industrialised over the past century and most, if not all African countries have electricity. Of course, large uninhabited or extremely rural areas of Africa would not have electricity. South Africa is the country in Africa that produces and consumes the most electricity.

Why do dead batteries bounce?
Dead batteries bounce because the chemical reaction inside the battery that produces energy has stopped, causing the battery to lose its weight and become lighter, allowing it to bounce more easily.
