CH3OH(g), and HCl(g), are combined in a 10.0 liter sealed reaction vessel and allowed to reach equilibrium at 400 K. The initial partial pressure of CH3OH(g) in the vessel is 0.250 atm and that of HCl(g) is 0.600 atm.

it is called acid bonding

explanation:

because it is

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
