Which statement describes a space-filling model of a molecule? A. The radii of the atoms are represented by the symbol of the atom surrounded by dots in the
space-filling model.

B. The radii of the spheres in a space-filling model are proportional in size to the radil of the atoms
they represent

C. The radii of the atoms present in the compound determine the length of the bonds in a space-
filling model.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally

i think tornado but not 100%
