If a straight-chain hydrocarbon is a gas at room temperature, how many carbon atoms will it have?

Chemistry
1 answer:
Orlov [11]3 years ago
6 0

The fewer the carbon atoms, the closer it is  to being a gas. The only one you have to check out is A which is hexane. You know that gasoline at the pumps has 8 carbons and its a liquid. So B and C are both not gases  because they are above 8.

C6 (hexane) is a liquid at room temperature not a gas.

The answer is D. If there is a gas present, it must be C3

Is cobalt 60 more dangerous than bananas ( potassium 40) and why ?
maxonik [38]

Answer:

To the best of my knowledge, it is because of the amount of gamma rays is given off.

Explanation:

While both are isotopes, Potassium 40 gives off fewer gamma rays compared to Cobalt 60. Potassium 40 isn't really harmful to humans, but Cobalt 60 (I believe) is used in chemotherapy.
