Which of the following options correctly reflect the relationship between dispersion forces and particle size? Select all that apply. Multiple select question. Larger particles are more polarizable and experience stronger dispersion forces. Dispersion forces are strongest for small particles since they can get closer together in space. Dispersion forces tend to decrease with size as larger particles are farther apart and therefore attract each other less. For molecules of similar shape, dispersion forces tend to increase with increasing molar mass.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

i believe the answer is true.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
