Moles of Sulfuric acid- H₂SO₄ needed to react completely : 3.2 moles
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction(balanced)
<em>2LiOH + H₂SO₄ → Li₂SO₄ + 2H₂O</em>
From the reaction equation above, the reaction coefficient shows the mole ratio of reagents and products
moles of Lithium hydroxide-LiOH = 6.4 moles
mol ratio of LiOH : H₂SO₄ = 2 : 1, so mol H₂SO₄ :

The angular momentum of an electron in the third Bohr orbit of a hydrogen atom is given by mvr=3h÷2π
<h3>What is momentum?</h3>
Momentum is defined as the amount of motion occurring in something that is moving, or the force that drives something forward to keep it moving.
Bohr never assumed stable electronic orbits with the electronic angular momentum quantized as
l=mvr =
Quantization of angular momentum means that the radius of the orbit and the energy will be quantized as well.
Bohr assumed that the discrete lines seen in the spectrum of the hydrogen atom were due to transitions of an electron from one allowed orbit/energy to another.

Answer:
B. The air pressure would increase 2X
Explanation:
Pressure = density × acceleration due to gravity × height
p = ρ × g × h
Pressure is force per unit area
p = F/a
Density is mass per unit volume
Pressure is directly proportional to density hence, any change in the density of a body directly affects the change in pressure of the body and vice versa.
The color change would only effect the appearance of the substance, so it would be a physical change.
Answer: physical change
