4.Why is liquid ammonia used as a refrigerant in ice plants, and what are its key advantages and disadvantages?
- A.It has a high latent heat of vaporization, is environmentally friendly, and has low electricity consumption, but is toxic and incompatible with copper.
- B.It is cheap and widely available, works well with copper pipes, and has no odor, but contributes to global warming.
- C.It has a low boiling point, is non-toxic, and does not react with metals, but requires high energy to compress.
- D.It is a natural gas, odorless, and highly efficient in small quantities, but depletes the ozone layer and is corrosive.
-
5.When ammonium chloride is mixed with sodium nitrite and heated, which products are formed? Select the correct set of products.
- A.Sodium chloride, nitrogen dioxide, and water.
- B.Sodium chloride, nitrogen gas, and water (steam).
- C.Ammonium nitrite and sodium hydroxide.
- D.Sodium chloride, ammonia, and oxygen.
