Why does the addition of an inert gas to a constant-volume equilibrium mixture of gases not disturb the equilibrium?.
Alecsey [184]

Answer:

Uhhhh I think this is it

Explanation:

Some changes to total pressure, like adding an inert gas that is not part of the equilibrium, will change the total pressure but not the partial pressures of the gases in the equilibrium constant expression. Thus, addition of a gas not involved in the equilibrium will not perturb the equilibrium.

Determine the molar solubility of pbso4 in pure water. ksp (pbso4) = 1.82 × 10-8.
OLga [1]
When PbSO₄ is added it dissociates as follows
PbSO₄ --> Pb²⁺ + SO₄²⁻
molar solubility is the number of moles of solute that can be dissolved in 1 L of solution 
if molar solubility of PbSO₄ is X, then molar solubility of Pb²⁺ is X and SO₄²⁻ is X
the formula for ksp is as follows 
ksp - solubility product constant
ksp = [Pb²⁺][SO₄²⁻]
ksp = X * X 
ksp = X²
ksp = 1.82 x 10⁻⁸ 
X² = 1.82 x 10⁻⁸ 
X = 1.35 x 10⁻⁴ M
molar solubility of PbSO₄ is 1.35 x 10⁻⁴ M
answer is b.

What causes the sea floor to move apart at a sea floor spreading center A density B continental drift C paleomagnetism D convect
pochemuha

Answer: D convection currents

Explanation:

The seafloor spreading is a phenomena that occurs due to liberation of heat from the convection currents generated in the mantle. It makes the earth crust more plastic and less dense. This happens at divergent plate boundaries. As the plates move apart, the less denser material rises. It leads to the formation of mountain and crust cracks.
