which type of reaction in a battery provides electrical energy?
538915
A - battery has 3 major componets. Acid, a salt bridge, and some type of metal (depending on the battery type... a nicad battery has nickel and cadmium for example).  Acid 'donates' a proton (H+) along the salt bridge, which in turn reacts with the metal.  This reaction is what produces energy.  The metal is oxidized.  Its been a while since I studied this, but overall, it is pretty close.

Over time, the barrier that separates the chemical components in the battery cannot maintain the electrical separation.  The reaction goes very very slowly, and the battery will eventually go bad.  Putting the battery in a lower temperature lowers the reaction rate, and hence the separator lasts longer and the battery's natural discharge rate is slowed.  Lower temperatures tend to inhibit chemical reactions; that's why we put food in there.  The bacteria that eat our food is inhibited at cool temps.

The battery has two terminals, one positive and one negative, with two different types of metals.  Floating inside the battery is also a supply of acid, which scientists would call an electrolyte.  This acid keeps the electrons flowing between the positive and negative terminals all the time.\n\nWhen you set up a wire loop, one end is connected to the positive terminal and the other is connected to the negative terminal.  The free electrons inside the battery like to flow from the positive down to the negative terminal.  Now they have a way out of the battery through the wire.\n\nThe electrons flow through the wire and anything else connected to it, like a small lightbulb.  Some of the electrons are used to make the filament inside the lightbulb glow red hot.  The rest of the electrons continue around the loop and end up at the positive terminal of the battery again.  This process keeps going until either almost all of the electrons are used up in the lightbulb (the battery is 'dead') or the circuit is broken.

Wow, brilliant question.  I don't think they do.  A battery moves electrons through a circuit in one direction (hence the name Direct Current) but for every electron, which has mass (9.1091 x 10 to the minus 28 grams), that goes out end of the battery, another electron with the same mass comes in.

Volts Per Cell.  I've no idea how many cells your battery comprises, but it's a guidleine to avoid overcharging.

There are lots of battery technonlogies. The common battery is made of carbon and zinc with an electrolyte that is primarily manganese. But other batteries use nickle/cadmium, nickle/metal hydride, mercury, lead/acid, and lithium compounds. So depends on what battery you are talking about.

Yes, it's purely chemical potential that drives neural impulses.  Recall what it is that powers batteries themselves?  Chemical potential.  In the voltaic cell or common battery this potential is generated by reactions between a chemical, most often a very strong acid like sulfuric acid, and some material, usually a metal like copper.  In the brain, the potential difference is a result of 2 chemicals, sodium and potassium.  That's it in a nutshell.

Batteries are self-contained chemistry sets, and chilling a battery slows down the reactions within that are slowly breaking down the alkali fluid, thereby preserving the electrical charge longer.\n\nLet's learn about electricity. Electricity is energy released from electrons travelling between atoms. Electrons can travel through any medium (air = lightning, you = electrocution), but they like conductive metals like copper the best, where they travel in a circuit, or a giant circle, between their origin and their destination. Electrons are stored in a battery like a sponge holds excess moisture.\n\nWithin a battery is a chemical (usually an alkali or an isotope-based solution) that retains electrons within like a sponge. Let's just say that battery fluid has properties about it that make it great for retaining excess electrons.\n\nWhen you chill a battery, you slow down the breakdown of the chemical within the battery housing (it will eventually break down into water + a precipitate), thereby preserving the charge that stores electrons. \n\nAnd remember, electrons in motion = electricity.

One example is Photosynthesis, an endothermic chemical reaction. In this process, plants use the energy from the sun to convert carbon dioxide and water into glucose and oxygen. \n\nThis reaction requires a tremendous amount of energy, 572 kJ to be exact. \n\n\n2H2 + O2 = 2H2O + ENERGY\nThis is also an example of an exothermic reaction, a reaction that produces energy. It is also an example of what is called a combustion reaction, where a substance (in this case hydrogen gas) is combined with oxygen. You are probably familiar with this reaction through two tragic examples of the unleashed energy of the combustion reaction of hydrogen, the Hindenburg, and the spaceshuttle Challenger. \n\n\n\n\nCan we create Hydrogen from Water?\nOh Yes! It's the same chemical reaction, but run in reverse: \n\n2H2O + ENERGY = 2H2 + O2 \nNotice now that the requirement is for energy to be ADDED TO the reactants. This is an example of an Endothermic reaction. This means that we could use Water as a Fuel! IF (and this is a big if) we could find an easy way to convert the water to hydrogen and oxygen, then the hydrogen could be used as a clean fuel.\n\nOne way to convert Water to Hydrogen and Oxygen is through the process of Electrolysis - using electricity as the source of energy to drive the reaction.

When O2 is exposed to lots of energy, you can get the reaction:\n\n3 O2 -> 2 O3\n\nWhere O3 is ozone.  Electrical activity (lightening) is typically the source for the energy.

In B, oxygen is a waste product of photosynthesis, but oxygen can also be produced in D. In electrolytic cells the electrolysis of salt water or acidic water is an  example of electrolysis. The ionic solution is driven by current and produces hydrogen gas in a reduction reaction at the cathode using electrons to complete the hydrogen ions. At the anode OXYGEN gas is produced in an oxidizing reaction and electrons are given off as the oxygen ions combine.

battery is used as a source of electricity. it can store energy of days or months.\nA capacitor on the other hand is an electronic component which stores charge for a very short time(around .5 seconds).It is used in electronic circuits.

Yes.  It consists in sticking two metallic objects of different kind, usually a galvanized nail and a copper coin, in a potato or lemon. These two objects work as electrodes, producing an electrochemical reaction that generates a small amount of electricity.

A) an oxidation reaction\n\nthat's why they are called redox

Electrochemical Cells are of two types:\n\nVoltaic Cells also called Galvanic Cells\nElectrolytic Cells\n\nAnions will move towards anode and cations will move towards cathode.\n\nAt anode oxidation will occur and at cathode redution will occur\nThe reactions in Volyaic cell are spontaneous and in Electrolytic cell are non-spontaneous\n\nFurther more info: plz check this foolwing web.

solar cells produce electricity through a process known as photoelectricity.Photoelectricity means a process in which light is shone (fall on) photocells which bring about the release of electrons.i.e.production of electricity .
