Ice made from water is a solid because the atoms or molecules > A. Vibrate in place
B. Are unable to move around
C. Are closely packed and touching
D. All of the above

D. all of the above

Explanation:

Ice made from water is a solid because the atoms or molecules

- vibrate in place

- are unable to move around

- are closely packed and touching

In a solid, the atoms or molecules are unable to move around so they just vibrate in fixed positions and they are closely packed and touching.

D. All of the above

hope this helps

answer is d because it is trust me

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.
