Best answer: Which reaction takes place in the presence of electricity?

What is chemical reaction in electricity?

Chemical reactions that can generate electricity are called REDOX reactions. REDOX reactions occur in the batteries you usually buy to power your electronic devices. REDOX reactions consist of two types of reactions. One is called reduction, while the other is called oxidation.

What produces electricity through a chemical reaction?

Batteries are devices that use chemical reactions to produce electrical energy.

Which reaction takes place in the presence of heat?

Answer: in the presence of heat thermal chemical reaction.

What type of chemical reaction takes place when electricity is passed through water?

Electrolysis of water is a decomposition reaction ; a single reactant breaks down into more than one product. The breaking down of H 2 O into H 2 and O 2 by passing electricity is known as electrolysis of water.

What are the examples of electrical energy?

Here are some examples of everyday objects that use electrical energy.

  • Washing machine.
  • Dryer.
  • Television.
  • Cell phone.
  • Laptop.
  • Air conditioning system.
  • Flashlight.
  • Heating system.

How is electricity produced in a battery?

Batteries produce electricity

A chemical reaction between the metals and the electrolyte frees more electrons in one metal than it does in the other. The metal that frees more electrons develops a positive charge, and the other metal develops a negative charge.

What is electricity made of?

Electricity is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons.

How do we generate electricity in chemistry?

Electricity is produced at a an electric power plant. Some fuel source, such as coal, oil, natural gas, or nuclear energy produces heat, which is used to boil water to create steam. The steam under high pressure is then used to spin a turbine that interacts with a system of magnets to produce electricity.

What type of reaction absorbs thermal energy?

endothermic: A description of a chemical reaction that absorbs heat energy from its surroundings.

Which form of energy is produced by an exothermic reaction?

In exothermic chemical reactions, the heat that is released by the reaction takes the form of electromagnetic energy or kinetic energy of molecules. The transition of electrons from one quantum energy level to another causes light to be released.

What is a catalyst and give an example?

A catalyst is substance i.e a element or a compound that increases the rate of chemical reaction. Examples: 1) Nickel, Ni is used in hydrogenation of palm oil into margarine. 2) Iron, Fe is used in Haber process. (
