The intermolecular forces between molecules in a liquid sample of sulfur trioxide, SO3 is London dispersion force.

<h3>What is intermolecular force? </h3>

The electrostatic forces of attraction present between molecules which hold them together are termed as intermolecular force.

<h3>Types of intermolecular force</h3>

Dipole dipole interaction
Dipole induced dipole interaction
van-der waal interaction
london dispersion force

<h3>What is london dispersion force? </h3>

This type of forces arises between symmetrical non- polar molecules. At a particular instant of time, the symmetry of molecules break and become unsymmetric. One side contain more electron than other. Having more electron become negative and other side get negative.

This unsymmetry make neighbouring molecule unsymmetric. The weak dispersion bond is formed between molecules called london dispersion force.

Thus, intermolecular forces between molecules in a liquid sample of sulfur trioxide, SO3 is london dispersion force.

Hiii pls help me to write out the ionic equation

emmasim [6.3K]

Answer:

<u>STEP I</u>

This is the balanced equation for the given reaction:-

$2KOH_{(aq)} + H_2SO_4{}_{(aq)} \rightarrow K_2SO_4{}_{(aq)} + 2H_2O_{(l)}$

<u>STEP II</u>

The compounds marked with (aq) are soluble ionic compounds. They must be

broken into their respective ions.

see, in the equation KOH, H2SO4, and K2SO4 are marked with (aq).

On breaking them into their respective ions :-

2KOH -> 2K+ + 2OH-
H2SO4 -> 2H+ + (SO4)2-
K2SO4 -> 2K+ + (SO4)2-

<u>STEP III</u>

Rewriting these in the form of equation

$\underline{\pmb{2K^+} }+ 2OH^- + 2H^+ + \pmb{\underline{{SO_4{}^{2-}}} \: \rightarrow \: \underline{\pmb{2K^+}}} + \underline{\pmb{SO_4{}^{2-}}} + 2H_2O$

<u>STEP </u><u>IV</u>

Canceling spectator ions, the ions that appear the same on either side of the equation

<em>(note: in the above step the ions in bold have gotten canceled.)</em>

$\boxed{ \mathfrak{ \red{ 2OH^-{}_{(aq)} + 2H^+{(aq.)} \rightarrow H_2O{}_{(l)}}}}$

This is the net ionic equation.

$\mathfrak{\underline{\green{ Why\: KOH \:has\: been\: taken\: as\: aqueous ?}}}$

KOH has been taken as aqueous because the question informs us that we have a solution of KOH. by solution it means that KOH has been dissolved in water before use.

The element of group 1 hour reactive but those of group 18 are inert, why?

Bogdan [553]

Answer:

The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to as the "inert gases" due to the fact that their filled valence shells (octets) make them extremely nonreactive.
