Which are applications of electrolysis? check all that apply.

the splitting of pure water into hydrogen and oxygen

the discharging of a battery to do work

the joining of aluminum and oxygen to become ore

the creation of a surface resistant to corrosion on metal surfaces

the use of tools to etch a permanent logo on materials

the oxidizing of the cathode during recharging

the preservation of artifacts like old coins

Answer;the splitting of pure water into hydrogen and oxygenthe creation of a surface resistant to corrosion on metal surfacesthe use of tools to etch a permanent logo on materialsExplanation;

Electrolysis is a process that involves forcing electricity through a liquid or solution called electrolyte to cause a reaction to occur.

Electrolysis has many applications and uses. These includes;

Anodization which is an electrolytic process that makes the surface of metals resistant to corrosion. Production of oxygen for spacecraft and nuclear submarines. Electroplating is used in layering metals to fortify them. Electroplating is used in many industries for functional or decorative purposes, as in vehicle bodies and nickel coins.Production of hydrogen for fuel, using a cheap source of electrical energy. Electrolytic Etching of metal surfaces like tools or knives with a permanent mark or logo. Electrolysis is also used in the cleaning and preservation of old artifacts. Etc.

They carry out the exchange of gases as we breathe ( oxygen and carbon dioxide).

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
