Answer:
See explaination
Explanation:
Go to the attached file for the detailed and step by step solution of the given.
Explanation:
The given data is as follows.
,
= 2257 kJ/kg,
= ?
For water,
= 4.184 
Formula to calculate heat of vaporization is as follows.
= 
Hence, putting the values into the above formula as follows.
= 
= 
= 2257 kJ/kg - 376.56 kJ/kg
= 1880.44 kJ/kg
Thus, we can conclude that enthalpy of liquid water at
is 1880.44 kJ/kg.
From the chemical equation given:
H2SO4+2KOH--->K2SO4+2H2O
the two reactants, H2SO4 and KOH, are in 1:2 stoichiometric ratio.
No. of moles of KOH = 2* no. of moles of H2SO4
=2*0.1*0.033
The concentration of KOH = no. of moles / volume
=2*0.1*0.033/0.05
=0.132M
In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment.
