Table sugar is not a mineral because: it is made of more than one element. it is not made by a geologic process. its chemical composition is always changing. it is in crystal form.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

i believe that it is a exoplanet

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
