Answer:- 
Explanations:- Alkanes are non polar molecules as these only have carbons and hydrogens. Electron negativity difference of C and H is very low and it makes them non polar. These have weaker London dispersion forces.
The forces of attraction becomes stronger in alkanes as the number of carbon increases because the surface area as well as molecular weight of the alkanes increases with an increase in number of carbons.
Butane has four carbons, propane has three carbons, ethane has two and methane has only one carbon, So, the strongest to weakest order of inter molecular forces is butane > propane > ethane > methane .
Answer:
Explanation: A square of dry ice has a surface temperature of - 109.3 degrees Fahrenheit (- 78.5 degrees C). Dry ice additionally has the extremely decent component of sublimation - as it separates, it transforms legitimately into carbon dioxide gas as opposed to a fluid.
Answer:
true
Explanation:
because if you find the right answer that proves the theory to be correct.
<span>The correct answer is the first option. Electron is not found in the nucleus of an atom. The sub-atomic particles of an atom are the
proton, electron and the neutron. An electron has a charge of -1 and a
smaller mass than a proton. Proton has the same mass with the neutron. The
ratio between the mass of a proton and an electron is about 2000. An electron
has an equal value but negative charge with the proton.</span>
I think the answer would be yes. if my math is correct 84,596 divided by 29 equals 2,917 sickles. 2,917 sickles is equal to 172 galleon. therefore he would have enough to buy the 70 galleon broomstick. hopefully i did this right and it helped!
