in rutherford's gold foil experiment a very small number of alpha particles were deflected. what about the structure of the atom

s that could have caused this?
Chemistry

zvonat [6]3 years ago
8 0

Answer:The atom being mostly empty space. A small number of alpha particles were deflected by large angles (> 4°) as they passed through the foil. There is a concentration of positive charge in the atom. Like charges repel, so the positive alpha particles were being repelled by positive charge

Choose the molecule or compound that exhibits dipole-dipole forces as its strongest intermolecular force.
LuckyWell [14K]

Answer:

SO2

Explanation:

Dipole-Dipole exist between parmanent dipoles in a molecule. THis means that molecule must have a parmanent dipole moment in it.

Example - HCl

Hydrogen bonding is an attraction between lone pair of an electronegative element and H atom of same or different molecule. H must be covalantly attached to either F, N or O.

Example - H2O

Among the molecules given in the list only SO2 and H2O exihibits parmanent moment. As BCl3 , CBr4 and H2 are symmetric compounds.

Since, SO2 cannot exihibit H- bonding only dipole-dipole forces as its strongest intermolecular force.

Methylamine (ch3nh2) is a weakly basic compound. calculate the kb for methylamine if a 0.253 m solution is 4.07% ionized.
MariettaO [177]
Answer is: Kb for methylamine is 4.37·10⁻⁴.<span>
Chemical reaction: CH</span>₃NH₂ + H₂O → CH₃NH₃⁺ + OH⁻.
c(CH₃NH₂) = 0.253 M.
α = 4.07% ÷ 100% = 0.0407.
[CH₃NH₃⁺] = [OH⁻] = c(CH₃NH₂) · α.
[CH₃NH₃⁺] = [OH⁻] = 0.253 M · 0.0407.
[CH₃NH₃⁺] = [OH⁻] = 0.0103 M.
[CH₃NH₂] = 0.253 M - 0.0103 M.
[CH₃NH₂] = 0.2427 M.
Kb = [CH₃NH₃⁺] · [OH⁻] / [CH₃NH₂]. 
Kb = (0.0103 M)² / 0.2427 M.
Kb = 4.37·10⁻⁴.

Which of the following changes would decrease the rate at which a solid solute dissolves in a liquid solvent?
andriy [413]

Answer:

Decreasing surface area of the solid in the liquid.

Explanation:

I don't know how to explain this without using. an example. So, here it is: If you were dipping bread in water, the bread would be completely soaked if you dipped the whole thing, but if you only allowed one part of the bread to be in the water, it would take longer for the water to soak all the way into it. The amount of surface area that is allowed to touch what is making the solid dissolve determines how quickly the whole thing will be dissolved.
