Answer:
Those in lightning are charged and those in water are not charged.
Explanation:
The particles in lightning differs from those in a water in that water molecules are neutral and those of lightning are charged.
Lightning is made up of charged ions or particles that have either lost or gained electrons.
Lightning is produced as a burst or discharge of charged particles that are imbalanced withing the clouds.
Water molecules are made up of hydrogen and oxygen atoms which forms molecules held together by strong intermolecular and interatomic bonds.
Due to the sharing of electrons that has made this bonding possible, there is a net charge balance which leads to a neutrality.
Water is electrostatically neutral and not charged.

Answer: The staircase is 14.28 m high.
Explanation:
Given : Mass = 0.1 kg
Potential energy = 14 J
Potential energy is the energy occupied by the position of a substance. Therefore, formula for potential energy is as follows.
P.E = mgh
where,
m = mass
g = gravitational energy = 
h = height of object
Substitute the values into above formula as follows.
Thus, we can conclude that the staircase is 14.28 m high.
Answer:
5x10⁻⁶ = [HTeH₄O₆⁺]
Explanation:
The first dissociation equilibrium of the telluric acid in water is:
H₂TeH₄O₆ + H₂O ⇄ HTeH₄O₆⁺ + H₃O⁺
Using H-H equation for telluric acid:
<em>pH = pKa + log₁₀ [HTeH₄O₆⁺] / [H₂TeH₄O₆]</em>
pKa of telluric acid is -logKa1
pKa = -log 2.0x10⁻⁸
pKa = 7.699
As concentration of [H₂TeH₄O₆] is 0.25M, replacing in H-H equation:
3.00 = 7.699+ log₁₀ [HTeH₄O₆⁺] / [0.25M]
-4.699 = log₁₀ [HTeH₄O₆⁺] / [0.25M]
2x10⁻⁵ = [HTeH₄O₆⁺] / [0.25M]
<h3>5x10⁻⁶ = [HTeH₄O₆⁺]</h3>
