Mantle convention, convection cells in the mantle, and produces horizontal motion of mantle material close to the Earth surface.
They are written as superscripts
The working equation for this is:
Tbp,soln - Tbp,water = i*Kb*m
where
Kb for water is 0.512 °C/molal
m is the molality (mol solute/kg solvent)
i is the van't hoff factor which represents the number of ions dissociated for strong electrolytes
Tbp,water is the boiling point of water which is 100°C
1. <span>1.50 moles of lioh (strong electrolyte) and 3.00 moles of koh (strong electrolyte) each in 1.0 kg of water
i = 2 for LiOH and 2 for KOH
Then,
</span>Tbp,soln - 100 = (2+2)(0.512)((1.5+3)/1 kg)
Tbp,soln = 109.22°C
<span>
2. </span><span>0.40 mole of al(no3)3 (strong electrolyte) and 0.40 mole of cscl (strong electrolyte) each in 1.0 kg of water
</span>
i = 4 for al(no3)3 and 2 for cscl
Then,
Tbp,soln - 100 = (4+2)(0.512)((0.4+0.4)/1 kg)
Tbp,soln = 102.46°C
<em>Thus, the first solution will have a higher boiling point.</em>
Answer:
HOCH₂CH₂CH₂OH Propane-1,3-diol
Explanation:
The boiling point of compound depends up on Hydrogen bonding and vander wall forces. The C option that is alcohol will have higest boiling point assuming that the mass is approximately same (between 60-80) and the boiling point is hight because this is due to extensive intra molecular hydrogen bonding in alcohol .Hence due to hydrogen bonding the molecules are packed close and that increases the boiling point of the molecule.The Answer is option C.
HOCH₂CH₂CH₂OH > CH₃CH₂CH₂CH₂OH > CH₃CH₂CH₂CH₂CH₃ > CH₃CH₂CH₂CH₂CH₃ > CH₃CH₂CH₂OCH₃
For exothermic reaction (that is heat is considered as a product) then
reactants= product + Energy ,
An decrease in temperature favors the forward reaction (more product formed)
pressure depends on number of mole of the product and reactants
a A + b B + c C + d D (Where a b c and d are numerical value and A B C and D are compounds) :
if more A is added to the equilibrium mixture, equilibrium position will shift to the right (more product formed) so as to decrease concentration of A
