In a redox reaction, which particles are lost and gained in equal numbers?(1) electrons (3) hydroxide ions(2) neutrons (4) hydronium ions
Answers
Answer: Option (1) is the correct answer.
Explanation:
A redox reaction is a reaction in which both oxidation and reduction takes place.
For example,
Oxidation-half reaction :
Reduction-half reaction :
Hence, we can see that electrons are involved in a redox reaction.
Therefore, we can conclude that in a redox reaction, electrons are the particles which are lost and gained in equal numbers.

The part of the nervoussystem is a gray, wrinkled organ consist of millions of neurons is the brain. Therefore, option B is correct.
What is nervous system ?
The nervous system is made up of the brain, spinal cord, and a sophisticated network of nerves. By this system, the body and the brain are transmitted. The brain performs every physical function. The spinal cord moves the brain through the back.
The brain and spinal volume unit are the organs of the central nauseous system. Since they are so vitally important, the brain and spinal cord, which are located in the dorsal body cavity, are protected by a bone shell.
Your entire body is controlled by your brain. Even when you sleep, it controls practically all of your behaviors and runs the show. For something the size of a wrinkled sponge of grey, it was really bad.
Thus, option B is correct.
