Answer:Butane > ethane > methane, because between bigger molecules there are stronger van der Waals forces and also higher molar mass means they need to be given more energy to have enough kinetic energy to move quickly, freely in gas.
There are multiple butene isomers (Butene) and some (2-Butenes - cis and trans) actually have higher boiling point than n-Butane (there is also Isobutane, of course, with quite much lower boiling point than all of them) and some (1-Butene, Isobutylene) have lower, so this isn't really a fair or simple question. But on simplest level, it can again be said that 1-butene has lower boiling point because it has very similar shape but slightly lower molar mass (2H less) than n-butane.
Explanation:
Correct Answer: compound because the atoms of the elements are combined in a fixed proportion.
All pieces will be 17 g/cm^3 because the density is not affected by cutting (assuming the rock is uniform).
Sulfur dioxide is an example of air pollution.
It is the main component of acid rain. It is released into the air as a result of the burning of fossil fuels.
