Is splitting water through electrolysis into O2 and H2 gasses a physical or chemical change?
In a way it is both physical and chemical, because a chemical change is changing how the molecule is "built," while a physical change is the transformation from one form to the other. I would consider splitting water through electrolysis as a chemical change at first because physical change is keeping the build of a molecule the same while it's form changes. You could also say that the splitting itself occurs first, meaning chemical change first occurs. Physical change would the occur later because the points of physical forms change based on the atom or molecule. The time difference in which occurs first would be very hard to measure, down to nanoseconds, but according to common scientific sense chemical change would occur first. The true answer to this question would be that it is chemical change, because you wanted to know what the splitting part was. Hope this helps!
What else can I help you with?
What is the name of the process for splitting apart compounds using electricity?
It is electrolysis becouse its a chemical reaction in which an electrical current is used to decompose a compound
What is the splitting of water molecules into hydrogen and oxygen molecules an example of?
The splitting of water molecules into hydrogen and oxygen molecules is an example of a chemical reaction known as electrolysis. This process involves passing an electric current through water to separate it into its constituent elements, hydrogen and oxygen.
What is the name of a device that converts electric energy to chemical energy?
The device is called an electrolyzer. It converts electrical energy into chemical energy by splitting water molecules into hydrogen and oxygen gases through a process called electrolysis.
When electrical energy is used to cause a chemical reaction we call this process?
When electrical energy is used to drive a chemical reaction, the process is called electrolysis. In electrolysis, an electric current is passed through a substance, usually in a liquid or molten state, causing the chemical compounds to break down into their constituent elements or ions. This technique is commonly used in applications such as electroplating, water splitting, and the extraction of metals from ores.
Which of these cannot be separated into its parts by an ordinary chemical or physicl process?
A compound cannot be separated into its parts by an ordinary chemical or physical process. Unlike mixtures, which can be separated through physical means, compounds require chemical reactions to break the bonds between their constituent elements. For example, water (H2O) can only be separated into hydrogen and oxygen through electrolysis, a chemical process.
What is a process that uses electric current to break chemical bonds?
Electrolysis is a process that uses electric current to break chemical bonds, typically in compounds dissolved in water. It involves the passage of current through an electrolyte to drive a non-spontaneous chemical reaction, causing the compound to decompose into its constituent elements.
How can metals be separated effectively?
Metals can be separated effectively through techniques such as filtration, distillation, and electrolysis. These methods exploit the differences in physical and chemical properties of metals to isolate them from each other.
Is passing electric current a physical or chemical?
Passing electric current through a substance typically results in a physical change rather than a chemical change. In conductors, the current can cause the movement of charged particles without altering the chemical composition of the material. However, in electrolytic processes, such as electrolysis, the current can lead to chemical reactions, resulting in the formation of new substances. Thus, whether it is physical or chemical depends on the context and the materials involved.
What event must take place to separate a compound into separate elements?
A chemical reaction must occur to separate a compound into its separate elements. This may involve breaking the bonds holding the elements together within the compound, typically through the addition of energy or the introduction of another reactant.
How are water molecules split apart?
If you use pass an electrical current through water to split it into hydrogen and oxygen, it is called electrolysis. If you use a chemical reaction to split water, then it is often called oxidation or reduction depending on the process. The splitting of water itself doesn't have a name, only the processes that are used to do it.
When an electric currents is passed through water during the process of electrolysis?
It is a chemical change which manifests a physical effect of gas being evolved from a liquid. If the gases already existed and were just coming out of solution, it would be a physical change, but since it is a change from water molecules to oxygen and hydrogen molecules it is definitely a chemical change, not a physical one.
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.
