What else can I help you with?
A puddle of water evaporates is an example of exothermic or endothermic?
Evaporation is an endothermic process.
Which one of the following is an exothermic reaction a electrolysis of water b conversion of lime stone into quick lime c process of respiration d process of photosynthesis?
The process of respiration is an exothermic reaction. During respiration, glucose is broken down in the presence of oxygen to release energy, carbon dioxide, and water. In contrast, electrolysis of water and the conversion of limestone into quick lime are endothermic processes, while photosynthesis is also endothermic as it requires energy from sunlight.
What is the breakdown of water into hydrogen to oxygen is an example of?
The breakdown of water into hydrogen and oxygen is an example of a chemical reaction known as electrolysis. This process involves passing an electric current through water to split it into its constituent elements, hydrogen and oxygen gas.
What compound is the process of dissolving in water exothermic?
The process of dissolving ammonium nitrate (NH4NO3) in water is considered endothermic, meaning it absorbs heat from the surroundings. However, an example of an exothermic dissolution process is the dissolving of sodium hydroxide (NaOH) in water. When NaOH dissolves, it releases heat, resulting in an increase in temperature of the solution.
Name of the process that decomposes water?
The process that decomposes water into hydrogen and oxygen gas is called electrolysis. It involves passing an electric current through water to split it into its constituent elements.
What is the name of a process by which water is broken down into hydrogen and oxygen?
It's an example of electrolysis. Not unwanted hair removal, but that does use the same process. Electrolysis is the process of breaking down compounds by running an electric current through them.

What is used as the anode in sodium chloride electrolysis?
For example titanium (electrolysis in water solution).

How do you prepare hydrogen from water at home?
by the process of electrolysis
When sodium hydroxide is dissolved in water the temperature of the water increases. Is this endothermic or exothermic?
This process is exothermic because it releases heat energy into the surroundings.
Is salt dissolving in water an example of an endothermic reaction yes or no?
No. The dissolving of salt in water is an exothermic process because it releases energy in the form of heat.
What is an electrolysis in science?
Electrolysis (coming from "electro", meaning electricity, and "lysis", meaning to cut) is the process whereby electricity is used to break apart a substance into two different substances. For example, electrolysis of water produces its constituent elemental gases, hydrogen and oxygen by this process: 2H20 + (electricity) --> 2H2 + O2
Is the formation of water endothermic or exothermic?
The process is endothermic because the water is absorbing heat from the kettle. When energy (heat) is released as steam this is exothermic.
What is Freezing water exothermic or endothermic?
Freezing water is an exothermic process because it releases heat energy as water changes from a liquid to a solid state. Heat is given off during the process of water molecules forming an orderly arrangement in ice.
