Chemistry

Tyndall effect is more effectively shown by lyophobic colloidal solution.

Type of back bonding:-

Therefore order of back bonding strength =>

BF₃ > BCl₃ > BBr₃ > Bl₃

The intermolecular association which is H-bonding is more prominent in case of primary amine as compared to secondary amines due to the availability of two hydrogen atom

V₂O₃ – Basic

CrO – Basic

Metal oxides are generally basic in nature but if more electronegative element are connected through central atom then deficiency of electron occurs on central atom and it behaves as acidic in nature.

Kindly consider the following figure

The Bond dissociation energy of D₂ is greater than H₂, therefore D₂ reacts slower than H₂.

This is chloroform reaction.

$Unitof\frac{a{n}^2}{V^2}=atm$

$Unitofa=\frac{atm*unitof{V}^2}{unitof{n}^2}$

$=\frac{atm*{\left(d{m}^3\right)}^2}{mo{l}^2}$

= atm dm⁶ mol^-2

Number of water molecule

Gypsum :- CaSO₄.2H₂O  =>          2

Plaster of paris :- CaSO₄.    =>          0.5

Dead burnt plaster : CaSO₄          =>          0

B and C are tranquilizers
