What else can I help you with?
Is using electricity to separate water into hydrogen and oxygen a chemical change?
Yes, using electricity to separate water into hydrogen and oxygen is a chemical change because it involves breaking the bonds between the hydrogen and oxygen atoms in water molecules to form separate hydrogen and oxygen molecules. This process is known as electrolysis.
Is electrolysis of NaCl a chemical change or not?
Electrolysis is a chemical change.
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.
Is electrolysis of water to form hydrogen and oxygen a physical or chemical change?
It is a chemical change because you are breaking the water into its elements, hydrogen and oxygen, and it is no longer water. I NEED THE NUMBER'S ^ Here They are Oxidation of ions or neutral molecules occurs at the anode, and the reduction of ions or neutral molecules occurs at the cathode. For example, it is possible to oxidize ferrous ions to ferric ions at the anode:Fe2+ aq → Fe3+ aq + e- It is also possible to reduce ferricyanide ions to ferrocyanide ions at the cathode:Fe(CN)3- 6 + e- → Fe(CN)4- 6
Which one is a chemical change distillation filtration oxidation and electrolysis?
There are two chemical changes in this series. Oxidation always involves chemical change. Electrolysis does too.
Is using a fuel cell to separate water into hydrogen and oxygen a physical or chemical separation?
Using a fuel cell to separate water into hydrogen and oxygen is a chemical separation process. It involves the electrolysis of water, which is a chemical reaction that breaks down water molecules into hydrogen and oxygen gases.
Are physical and chemical change different?
Physical change does not produce a new substance. Chemical change produces a new substanceIn a chemical change the atoms/molecules are chemically joined together so they are very hard to separate. were as they are easyer to separate in a physical change
Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
The electrolysis of water is a chemical change because it breaks down water molecules into hydrogen and oxygen gas. On the other hand, sodium chloride exposed to sunlight is a physical change as it may undergo phase changes, but the chemical composition remains the same.
Justify why electrolysis of water is a chemical irreversible change?
A chemical change is always irreversible; that's part of the definition of "chemical change". This is because a new substances with new properties are formed. In this example, hydrogen and oxygen gas.
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.
Are the changes produced by electrolysis chemical or physical in nature?
The changes produced by electrolysis are chemical in nature. The process involves the conversion of electrical energy into chemical energy, resulting in the decomposition of compounds into their constituent elements or ions.
Is electroplating physical or chemical change?
Electroplating involves a combination of physical and chemical changes. The metal ions (chemical change) in the solution are reduced and deposited onto the object's surface using electricity (physical process).
