Answer:
0.0039 mol/L
The molar solubility is 0.0039 mol/L, thus the common ion effect has reduced the solubility from 0.016 mol/L for Ag2SO4 in pure water to 0.0039 mol/L in the Na2SO4 solution.
Explanation:
B. Holding spores
B is the answer
1.25 *10^2
25*5 = 125
= 1.25 *10^2
1: a, 2:a, 3:a, 4:c, 5:d, 6:d, 7:c;

4Fe + 3O₂ → 2Fe₂O₃
Fe → ²⁺
O → ²⁻
But Iron III is Fe³⁺
So we have Fe³⁺ and O²⁻, the formula for the oxide must be Fe₂O₃ so the equation can be:
