Which one of the next salts is the most soluble in water, if: Ksp (BaCO3) = 5.1 • 10-9 mol2 / l2; Ksp (CaCO3) = 4.8 • 10-9 mol2
lubasha [3.4K]

Answer:

Explanation:

Ksp (BaCO₃) = 5.1 x  10⁻⁹

Ksp (CaCO₃) = 4.8 x  10⁻⁹

Ksp (BaSO₄) = 1.1 x  10⁻¹⁰ = .11 x 10⁻⁹

Since solubility product of BaCO₃ is  greatest , its solubility is maximum .It is to be noted that all of them will be giving only two number of ions after dissolution in water .

BaCO₃ = Ba⁺ + CO₃⁻

Ksp = [ Ba⁺²] [ CO₃⁻² ]

= [ Ba⁺²]²

[ Ba⁺²] = √ Ksp

similarly we can find equations for others .

Which type of cell can have a flagellum or cilia
Y_Kistochka [10]

Answer:

Both prokaryotic and eukaryotic cells contain structures known as cilia and flagella. These extensions from the cell surface aid in cell movement. They also help to move substances around cells and direct the flow of substances along tracts. Cilia and flagella are formed from specialized groupings of microtubules called basal bodies.
