Answer:
Renewable source of energy
Using unrenewable sources is destroying the earth
Answer:
T°fussion of solution is -18°C
Explanation:
We have to involve two colligative properties to solve this. Let's imagine that the solute is non electrolytic, so i = 1
First of all, we apply boiling point elevation
ΔT = Kb . m . i
ΔT = Boiling T° of solution - Boiling T° of pure solvent
Kb = ebuliloscopic constant
105°C - 100° = 0.512 °C kg/mol . m . 1
5°C / 0.512 °C mol/kg = m
9.7 mol/kg = m
Now that we have the molality we can apply, the Freezing point depression.
ΔT = Kf . m . i
Kf = cryoscopic constant
0° - (T°fussion of solution) = 1.86 °C/m . 9.76 m . 1
- (1.86°C /m . 9.7 m) = T°fussion of solution
- 18°C = T°fussion of solution
Answer : The temperature in kelvins is, 
Explanation : Given,
= 178.5 KJ/mole = 178500 J/mole
= 161.0 J/mole.K
Gibbs–Helmholtz equation is :

As per question the reaction is spontaneous that means the value of
is negative or we can say that the value of
is less than zero.

The above expression will be:



Now put all the given values in this expression, we get :


Therefore, the temperature in kelvins is, 
When one observes the phase of matter of water, one observes a physical property of matter.
