Answer:
2KOH(aq) + H2SO4(aq) ⇒ K2SO4(aq) + 2H2O(l)
Explanation:
The reaction is a neutralization reaction since an acid, aqeous H2SO4 reacts completely with an appropriate amount of alkali, aqueous KOH to produce salt, aqueous K2SO4 and liquid water, H2O only.
2KOH(aq) + H2SO4(aq) ⇒ K2SO4(aq) + 2H2O(l)
Alkali + Acid → Salt + Water.
During this reaction, 2 moles of KOH neutralize 1 mole of H2SO4 to yield 1 mole of K2SO4 and 2 moles of H2O.

Answer:
The uncertainty in the position of the electron is 
Explanation:
The Heisenberg uncertainty principle is defined as:
≥ 
(1)
Where 
is the uncertainty in momentum, 
is the uncertainty in position and h is the Planck's constant.
The momentum is defined as:
(2)
Therefore, equation 2 can be replaced in equation 1
≥
Since, the mass of the electron is constant, v will be the one with an associated uncertainty.
≥ (3)
Then, can be isolated from equation 3
≥ 
(4)
But 
Hence, the uncertainty in the position of the electron is
Answer:
Noise in the environment
Electrons emitted via the photoelectric effect
Explanation:
Physical entropy can be seen as a disorderliness that can be observed in a physical system. The noise in a physical system can be used for secure number generation because of its randomness.
Noise is known to have no defined pattern and hence, can be used to creates secure random key generations.
Electrons emitted via the photoelectric effect: Electrons are emitted in a random order whenever a beam of light is incident on a photoelectric material. These electrons emitted can be used for random key generations
