Answer:
if balanced reaction then 2 NaOH + MgSO4 → Mg(OH)2 + Na2SO4
Explanation:
A critical mass is the smallest amount of fissile material needed for a sustained nuclear chain reaction.
Answer:

Explanation:
The formula for the force exerted between two ions is

where the Coulomb constant
k = 8.988 × 10⁹ N·m·C⁻²
Data:
z₁ = +2; r₁ = 0.62 nm
z₂ = -1; r₂ = 0.121 nm
Calculations:
r = r₁ + r₂ = 0.62 + 0.121 = 0.741 nm

I think the correct answer from the choices listed above is option D. The statement t hat describes a characteristic of a terminal moraine would be that it <span>can pluck pieces of rock out of a mountain to create a circular basin. Hope this answers the question. Have a nice day.</span>
