Answer:
Explanation:
Hello, there are two properties of alkaline metals that make them have that behavior:
1. They have large electrode potential which allows them to displace the hydrogen in the water.
2. They released energy when the hydrogen is displaced is big enough to make it ignite.
Now, the reaction is more violent when increasing the period of the alkaline metal because the higher the period (atomic radius as well) the higher the electrode potential which increases the released energy.
Best regards.

Solution properties are the properties of a solution that don't depend on the type of solute but only on the concentration of the solute.
Solutions from volatile substances have a higher boiling point and lower freezing points than the solvent
For freezing point can be formulated
K = molal freezing point constant
m = molal solution
A solution with a freezing point of -5.8 ∘C
Answer:
The correct answer is: K'= 0.033.
Explanation:
The formation of HI from H₂ and I₂ is given by:
H₂ + I₂ → 2 HI K= 29.9
The decomposition of HI is the reverse reaction of the formation of HI:
2 HI → H₂ + I₂ K'
Thus, K' is the equilibrium constant for the reverse reaction of formation of HI. It is calculated as the reciprocal of the equilibrium constant of the forward reaction (K):
K' = 1/K = 1/(29.9)= 0.033
Therefore, the equilibrium constant for the decomposition of HI is K'= 0.033
