Calcium oxalate (CaC2O4) has a Ksp value of 2.3 × 10–9 at 25°C. Calculate the molar solubility of Ca2+ and C2O42– in one liter o
mart [117]
Ksp is the equilibrium constant of solubility of a solid in a solution.

The solid is CaC2O4.

The dissolved ions are Ca2+ and C2O4 2-

The equation of the equilibrium is
CaC_{2}O_{4} = Ca^{2+} +  {C_{2}O_{4}}^{2-}

Then Ksp = [Ca 2+][C2O4 2-]

Where the [ ] indicates molar concentration

The chemical equation for this equilibrium implies [Ca 2+] = [C2O4 2-]. Name X this quantity

Ksp = x^2 ==> x = square root of Ksp

x = sqrt(2.3 * 10^ -9) = 4.8 * 10^ -5

Which is the second option.

Draw two water molecules interacting with a methanol (CH3OH) molecule through hydrogen-bonding.
abruzzese [7]

Answer:

The answer is in the picture.

Explanation:

The methanol molecule is on the top.  

the three molecules are drawn in blue (the two water molecules and the methanol molecule), with the hydrogen bonds indicated with dashed lines.  There are also oxygen lone pairs drawn as red dots, and the zones of negative density ( δ-, high concentration of electrons) and zones of positive density (δ+, low concentration of electrons) are marked.
