The Lewis dot model of a molecule is shown. Based on the model, which of the following is true? (5 points) O Oxygen is the least electronegative of the three atoms.
O Carbon has a total of four bonded pairs of electrons around it.
O Oxygen has four pairs of non-bonding innermost shell electrons.
O Carbon has an incomplete octet as it transfers an electron to each hydrogen.​

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

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

so whats the answer tell me
