Which molecule has the greatest Electronegativity differences? a. HCl b. HI c. HF d. HBr e Naci
Which molecule is laas

If E. is NaCl that is correct, if it is not, then A. I can't tell with typo

Explanation:

Electronegativity rises across period, and up a group.

idk what is it? is this a question that you know the answer or u dont

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
