Answer:
Dmitri Mendeleev
Explanation:
Dmitri Mendeleev a Russian Chemist arranged elements on the periodic table according to their atomic mass. He used this arrangement to predict some of the properties of the missing element.
- Dmitri Mendeleev around 1869 described the periodic table.
- The table was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
- In the Mendeleev table, elements are arranged by atomic weights with recurring properties in a periodic manner.
Answer is: molar solubility of nickel(II) carbonate is 3.77·10⁻⁴ M.
Chemical reaction:NiCO₃(s) → Ni²⁺(aq) + CO₃²⁻(aq).
Ksp = 1.42·10⁻⁷.
s(NiCO₃) = ?M.
s(NiCO₃) = s(Ni²⁺) =s(CO₃²⁻) = x.
Ksp = s(Ni²⁺) · s(CO₃²⁻).
Ksp = x · x.
1.42·10⁻⁷ = x².
x = √1.42·10⁻⁷ = 3.77·10⁻⁴ M.
