e average bond order is the number of bonds between two atoms taking into account resonance. Draw a Lewis structure for ozone an
sineoko [7]

Answer:

See Explanation

Explanation:

Resonance is a valence bond terminology which is used to describe a situation in which a single structure is not able to fully describe the nature of bonding in a molecule.

In such cases, we invoke more than one structure. Each structure contributes significantly to our understanding of the nature of bonding in the molecule under consideration and these structures are called canonical or resonance structures.

The real structure of the molecule is somewhere in between these structures -  a resonance hybrid.

For ozone, two equivalent structures can be used to describe the bonding in the molecule. These structures are equivalent as shown in the mage attached. We can see from these structures that the bond order in ozone is 1.5(one and half bonds)

Calculate the molar solubility of lead thiocyanate in pure water. The molar solubility is the maximum amount of lead thiocyanate
OLga [1]

Answer:

Molar solubility(S)=1.71\times10^{-2} mole/litre

Explanation:

Assume Ksp of Pb(SCN)_{2}=2\times10^{-5}( it is general value ,i took it because not given in question)

molar solubilty means how much maximum mole of lead thiocynate is dissolved in one litre of solvent.

Ksp=solubility product;

Pb(SCN)_2= Pb^{2+}  +2SCN^-

Lets molar solubilty of Pb(SCN)_2 is S then

[Pb^{+2}]=S;

[SCN^{-1} ]=2S;

Ksp =S\times(2S)^{2} =2\times10^{-5}

4S^{3}=2\times10^{-5}

S=1.71\times10^{-2} mole/litre
