Answer:
Option (1)
Explanation:
The incomplete combustion of fossil generally occurs when there is less amount of air or oxygen. This incomplete combustion leads to the production of carbon monoxide and carbon along with water. It does not release any carbon dioxide.
The reaction that represents an incomplete combustion is-
Hydrocarbon (fossil) + oxygen (O₂) → Carbon Monoxide (CO) + carbon (C) + water (H₂O)
.
This reaction releases this Carbon monoxide which is a very poisonous gas. This gases are trapped in the lungs and it creates difficulty for the blood to carry oxygen. This is the reason why the complete combustion of fossil is more preferred compared to the incomplete combustion.
Hence, the correct answer is option (1).
Answer:
Neptune
Explanation:
The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion miles).
