Helium can be liquefied when he atoms are attracted to one another by intermolecular ________ forces.
Akimi4 [234]

Helium can be liquefy through a very low temperature because of the weakness of attractions between the helium atoms. In addition, helium is a noble gas that has a very weak interatomic London dispersion forces. Thus, this element would remain liquid at atmospheric pressure all the way to its liquefaction point going to absolute zero.

ladessa [460]

The correct answer is From different social and ethnic backgrounds.

Explanation:

The purpose of science studies is to gain an understanding of specific phenomena and use this in the benefit of the world or humanity. Moreover, science is guided by objective methods and these are applied all around the world. This feature allows scientists from all kinds of social and ethnic backgrounds to study the same phenomena and obtain similar results, which is essential for the progress of scientific knowledge. This is exemplified by two different labs in two different countries studying drug absorption because the results of these two studies can be analyzed together to understand drug absorption.

In this context, one factor that contributes to the progress of scientific knowledge is the effort of scientists "from different social and ethnic backgrounds".

Determine which of these properties would distinguish these two substances: (a) boiling point; (b) combustion analysis results;
Nutka1998 [239]

Answer:

(a) boiling point

(d) density at a given temperature and pressure.

Explanation:

Isomers are compounds that have the same molecular formula but different structural formulas. They differ in chemical and physical properties depending on the type of isomerism displayed by the compounds.

The compounds stated here are structural or constitutional isomers hence they possess different boiling points and densities at a given temperature and pressure owing to structural differences in the molecules.

Since they have the same molecular formula, they must yield the same result during combustion analysis and they must have the same molecular weight.
