Answer:

D) Dispersion; dispersion

Explanation:

Pentane or heptane are non-polar molecules so both of the , dispersion or london force exists as intermolecular force exists among molecules of pentane or heptane . So these bonds needs to be broken and dispersion  interaction takes place between molecules of pentane and heptane. Dispersion interaction  of AB type is stronger than AA or BB type.

Chlorine, which has an atomic mass of 35.453 amu, has two naturally occurring isotopes, Cl-35 and Cl-37. Which isotope occurs in
Pachacha [2.7K]

Cl-35 occurs in greater abundance.

The <em>weighted atomic mass</em> lies <em>closer to 35 u</em> than to 37 u, so the Cl-35 isotope must be more abundant.

What concentration of so32– is in equilibrium with ag2so3(s) and 2.60 × 10-3 m ag ? the ksp of ag2so3 can be found here?
lubasha [3.4K]
When the Ksp of Ag2SO3 is 1.5 x 10^-14 

and when the reaction equation is:

 Ag2SO3 ↔ 2Ag+(aq) +  SO3-- (aq)

so,

Ksp = [Ag+]^2 *[SO3--]

by substitution:

1.5 10^-14 = (2.6 x 10^-3)^2 *[SO3--]


∴ [SO3--] = 2.2 x10^-9
