Answer: Option (d) is the correct answer.
Explanation:
It is known that water loving bonds are called hydrophilic bonds and water hating bonds are called hydrophobic bonds. Since, water is a polar solvent and it is only able to dissolve polar molecules and not non-polar molecules.
Lattice of water and hydrogen bonding are responsible for the various properties of water like cohesion, adhesion, heat of vaporization etc.
Thus, we can conclude that water lattice excludes non-polar substances.
Answer:
is the rate constant for this reaction.
It will take 
to concentration to reach 12.5% of its original value.
Explanation:
A decomposition reaction follows first order kinetics:
Half life of the reaction = 
Rate constant of the reaction = k
For first order reaction, half life and rate constant are linked with an expression :
is the rate constant for this reaction.
Initial concentration of reactant =![[A_o]](https://tex.z-dn.net/?f=%5BA_o%5D)
= x
Final concentration of reactant after time t =![[A]](https://tex.z-dn.net/?f=%5BA%5D)
= 12.5% of x = 0.125x
The integrated law of first order reaction :
![[A]=[A_o]\times e^{-kt}](https://tex.z-dn.net/?f=%5BA%5D%3D%5BA_o%5D%5Ctimes%20e%5E%7B-kt%7D)
t = 1,734.31 years =
It will take to concentration to reach 12.5% of its original value.
Answer:
Ba(OH)2 + H2SO4 ------> BaSO4 + 2H2O
1) Moles of Ba(OH)2 = moles of H2SO4 = 0.025L x 2)0.02M = 5.0 x 10^-4M
Concn of Ba(OH)2 in g/L = 5.0 x 10^-4M x 171.33g/mol = 0.086g/mol
