How do ions become molecules at the electrodes?
The electrons are either gained or lost because free electrons are what conducts electricity so they can escape or be captured in reduction or oxidisation.
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 gases conduct electricity when pressure is reduced in discharge tube?
When the pressure is reduced in a discharge tube, the mean free path of the gas molecules increases. This allows the gas molecules to gain more energy and move freely, colliding with the charged particles in the discharge tube and facilitating the flow of electric charge. As a result, the gases become partially ionized, creating a conductive path for the electricity.
Why does electrochemical cell stop functioning after some time?
The battery that we use in day to day appliances generates electricity( about 3.5V / 12V) as a result of the electrochemical reaction between the metal and electrolyte ( Sulphuric acid in case of Lead-acid battery). As the reaction goes on , the ions in the electrolyte combine with the metal to form a salt and electrical energy. Once these ions are exhausted, the voltage level becomes very low or nil. If the battery is a rechargeable one, then the electricity supplied in reverse direction charges the ions in the electrolyte. After sufficient, charging the battery can be used again.
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!
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.
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.
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.
Is cardboard a good conductor of electricity?
Cardboard is an insulator of electricity. It is not the best insulator to use for this as cardboard can be affected by moisture and any corrosion of nearby batteries. If it becomes wet with an electrolyte solution (such as salt water), it could become a conductor under certain conditions.To test this, put a battery and a light in series and leave the contacts open between the light and the battery. Then touch the wire to the cardboard and the cardboard to the battery. The light will not light up.
Does the laptop become heavier after charging the battery?
No, the charge in the battery is a change in state of the battery contents, not an addition to the battery.
Why is there voltage between the electrods of an electrochemical cell?
Chemical reactions occur between the electrolyte and the electrodes in an electrochemical cell. These reactions cause one electrode to become positive to become negatively charged and the other electrode to become positively charged. Since they have opposite charges there is a voltage between them. Basically, The voltage is caused by the electrodes having a different charge and are able to conduct through them.
