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:
To the right
Explanation:
CH₃OH(g) + heat <=> CO(g) + 2H₂(g)
According to Le Chatelier's principle, a decrease in pressure will shift the equilibrium position to the side where there is a higher volume.
From the balanced equation above,
Volume of reactant = 1
Volume of product = 1 + 2 = 3
From the above, we can see that the volume of the gasous product is higher than the volume of the gasous reactant.
Therefore, a decrease in the pressure of the system will shift the equilibrium position to the right.
If you mean what group of elements react the most, the answer is the alkali metals and the halogens because they both only either need to gain or lose one electron. If you mean the most reactive element, it would be fluorine because it has the most electronegativity.
