Question

___ fumes confirm the presence of ammonia gas.

a.) Dense Red

b.) Dense White

c.) No fumes

d.) None of the above​

Answer 1

The correct answer is (a) Dense Red. Dense Red fumes confirm the presence of ammonia gas.

Step-by-step explanation:

Ammonia gas has the ability to release dark crimson fumes when it comes into contact with specific materials. Ammonia gas can emit dark crimson smells when it interacts with specific compounds. Nitrogen dioxide (NO2) is produced during this reaction, which causes it to happen. Nitrogen dioxide is a reddish-brown gas with a pungent odour that is extremely hazardous. Ammonia gas is present because of the intense crimson fumes that are produced when nitrogen dioxide and ammonia combine.

Answer 2

(b) Dense White

Step-by-step explanation:

Ammonia gas is a colorless gas with a strong odor. It can be detected by its characteristic pungent odor. When ammonia gas is mixed with hydrochloric acid, it forms a dense white smoke of ammonium chloride.

So the presence of dense white fumes confirms the presence of ammonia gas.

Therefore, the answer is (b) Dense White

The other options are incorrect.

• Dense red fumes are not associated with ammonia gas.
• No fumes means that there is no ammonia gas present.
