Question 959 Deck General

The correct answer is C) it is odorless. Methane (CH4) is the simplest alkane hydrocarbon gas and a major component of natural gas. As a characteristic, methane is indeed odorless in its natural state. This is because methane does not have a distinct smell that humans can detect. In contrast, the other answer choices do not accurately describe the properties of methane gas. Methane is not corrosive (A), it is volatile (flammable) but not inherently active (D), and it is not considered a reactive gas (D).
