Which phrase best defines a mountain eee

Option (D)

Explanation:

Mountain range refers to the chain of mountains and the different mountain ranges are separated from one another by rives and the valleys, that flows through them. These mountain ranges are formed by the  convergence of two continental plates, that forms a sandwich pattern, thereby forming huge mountain ranges, such as the Himalayas.

Thus, the correct answer is option (D).

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
