Is passing electric current through a heater rod itphysical or chemical change?
Passing electric current through a heater rod is primarily a physical change. The process involves the conversion of electrical energy into thermal energy, which heats the rod without altering its chemical composition. While this heating can lead to physical changes, such as expansion, the material itself remains unchanged at the molecular level. Therefore, no new substances are formed, indicating a physical rather than a chemical change.
Is the heating element on a stove a chemical reaction?
No. It is a physical process cause be passing an electric current through a wire.
Is physical or chemical break up water by separating it into O2 and H2?
It is a chemical breakup that is achieved through passing a direct electric current through a weak solution of salt in water. The energy used to achieve this is theoretically equal to the energy released when the same free hydrogen and oxygen recombine in an explosion.
What is the process of initiating a chemical reaction by passing an electric current through an electrolytic solution?
This process is the thermal decomposition.
Passing a magnetic field by a wire creates a what?
Passing a wire near a magnetic field induces an electric current in the wire.

Is decomposing water by passing an electric current through it a chemical or physical change?
Decomposing water by passing an electric current through it is a chemical change because it involves the breaking of the chemical bonds in water molecules (H2O) to form hydrogen gas (H2) and oxygen gas (O2). This reaction results in the formation of new substances with different chemical properties.
Is a filament of a light bulb glows when an electric current flows through it is a chemical change?
It is a physical change brought about by the exitation of molecules producing heat and light. A general rule of thumb is that a physical change can be repeated on an article and chemical change cannot. Remove the current from a filament and it is still a filament.
Who discover chemical effect of electric current?
The chemical effect of electric current, known as electrolysis, was discovered by William Nicholson and Anthony Carlisle in 1800. They found that passing an electric current through water caused it to split into its constituent elements, hydrogen and oxygen.
Is the heating element on a stove a chemical reaction?
No. It is a physical process cause be passing an electric current through a wire.
What is the process of breaking down something using an electric current?
Electrolysis is the process of using an electric current to break down a chemical compound into simpler substances. It involves passing an electric current through a conducting solution or molten compound, causing the compound to decompose into its constituent elements or ions.
What are electromagents?
Magnets that are turned on by passing an electric current through them, and turned off by not allowing an electric current through them.
Is physical or chemical break up water by separating it into O2 and H2?
It is a chemical breakup that is achieved through passing a direct electric current through a weak solution of salt in water. The energy used to achieve this is theoretically equal to the energy released when the same free hydrogen and oxygen recombine in an explosion.
Which type of chemical reaction takes place when electric current is passed through water?
The process is called electrolysis, and it usually results in a decomposition reaction. For example, passing an electric current through water results in the reaction 2H2O --> 2H2 + O2.
What is the process of initiating a chemical reaction by passing an electric current through an electrolytic solution?
This process is the thermal decomposition.
What molecules make h2o?
mainly, an electric current passing throught
Clearly state the definition of electrolysis?
Electrolysis is a chemical process where an electrolyte is chemically decomposed into its consituents by passing an direct electric current through it inside an electric cell.
