• An example of electrolysis is the combustion of gasoline in a car engine.

• Electrolysis involves heating a substance to break it down into simpler components.

• Electrolysis is the process of using magnets to separate substances.

What is corrosion and how can it be prevented in metals?

• Corrosion can be prevented by exposing metals to harsh environments.

• Corrosion is the process of strengthening metals through chemical reactions.

• Corrosion is the process of deterioration of metals due to chemical reactions with the environment. It can be prevented by using protective coatings, such as paint or plating, applying inhibitors that slow down the corrosion process, using corrosion-resistant metals, or controlling the environment to reduce exposure to corrosive elements.

• Corrosion is caused by protecting metals with coatings.

Discuss the role of electrochemistry in the production of batteries.

• Batteries are solely produced through mechanical processes

• Electrochemistry enables the conversion of chemical energy into electrical energy through redox reactions in batteries.

• Electrochemistry has no role in battery production

• Redox reactions in batteries are not related to electrochemistry

How does electroplating work and what are its practical applications?
