What is the primary component in hydrogen peroxide used for hair bleaching?

Ammonia
Cyanide
Oxygen
Sulfur

The correct answer is: Ammonia

Ammonia is the correct answer because it is the primary component in hydrogen peroxide used for hair bleaching. Ammonia works by opening the hair cuticle to allow the hydrogen peroxide to penetrate and break down the natural hair pigment. This process lightens the hair color, making it an essential ingredient in hair bleaching products. Option B, Cyanide, is incorrect as it is a highly toxic chemical that is not used in hair bleaching products. Option C, Oxygen, is incorrect because although hydrogen peroxide does contain oxygen, ammonia is the primary component responsible for the hair bleaching process. Option D, Sulfur, is also incorrect as it is not the primary component in hydrogen peroxide used for hair bleaching.
