Something that’s strange or doesn’t happen often
in a sentence “ in all his travels he studied only the phenomena of nature and life
Density = mass / volume
D = 1 x 10⁴ / 2
D = 5000 kg/m³ in g/cm³:
1 kg/m³ ---------------- 0.001 g/cm³
5000 kg/m³ ----------- ??
5000 x 0.001 / 1 => 5.0 g/cm³
hope this helps!
Answer:
London dispersion forces
Explanation:
There are different forces of attraction that helps to hold atoms or Molecules of a particular substance together. Some of the forces of attraction are ionic/ electrovalent bond, covalent bond, vander waals forces of attraction and so on.
Under the vander waals forces of attraction we have what is known as the London dispersion forces. This force of attraction is a very weak and it is commonly found in the atoms of noble gases.
The intermolecular force of attraction in which we are talking about that is london dispersion forces is formed as a result of the formation of non-polar dipoles which are not permanent.
Answer:
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.
