What type of reaction takes place when electric current is passed through water?
When electric current is passed through water, it splits up into hydrogen & oxygen. This is called electrolysis of water.
What type of chemical reaction take place when electricity is passed through?
Answer: When an electric current is passed through water Electrolytic decomposition takes place.
What type of reaction takes place in water?
Three important types of reactions in water are precipitation, acid-base, and oxidation-reduction reactions.
What type of chemical reaction takes place when electricity is passed through water a displacement B combination C decomposition and double displacement?
Electrolysis of water is a decomposition reaction.
What type of chemical reaction takes place when electricity is passed through Aluminium oxide?
This is a decomposition reaction.
What type of reaction is Pb CuCl2?
The correct answer is displacement. Pb + CuCl2 → PbCl2 + Cu. The given reaction is an example of a displacement reaction. A reaction in which one element is replaced by another element of the compound is known as displacement reaction.
What type of chemical reactions take place when electricity is passed through sodium chloride?
Explanation : When electricity is passed through an aqueous solution of sodium chloride, it gives hydrogen, chlorine and sodium hydroxide as a product. The balanced chemical equation is, This process is called as Electrolysis of Brine.
What type of chemical reaction takes place when digestion of food occurs in the body?
Digestion of food in our body is a decomposition reaction.
What type of reaction is electrolysis of water?
The electrolysis of water is an example of a non spontaneous redox reaction that occurs in the presence of electricity (energy).
What is chemical reaction of water?
Each oxygen molecule supplies two oxygen atoms so will always form two water molecules, provided there are two hydrogen molecules (each being a unit of two atoms) to react with it. Thus two molecules of hydrogen and one molecule of oxygen are needed to make two molecules of water.
Which of the following reaction is a decomposition reaction?
A decomposition reaction occurs when one reactant breaks down into two or more products. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
Which of the following involves chemical reaction?
Hence, Heating copper wire in the presence of air at high temperature is a process that involves chemical reaction. Therefore, the correct answer is option (D). Note: The substance (or substances) that are initially involved in a chemical reaction are known as reactants or reagents.
What type of chemical reaction takes place when limestone is heated?
When limestone is heated in a kiln, the calcium carbonate breaks down into calcium oxide and carbon dioxide. This type of reaction is called thermal decomposition. The process is called calcining.
