A proposed mechanism is: C4H9Br --> C4H9^+ + Br^– (slow)
C 4H9^+ + H2O --> C4H9OH2^+ (fast)
C4H9OH2^+ + H2O --> C4H9OH + H3O^+ (fast)

i. What are the mechanism’s intermediates?
ii. Write the reaction’s overall balanced equation.

iii. Write the correct rate law, based on the given mechanism.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)

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
