Cuprite, Cu2O, has a body-centered cubic unit cell of oxide anions with four copper cations in a tetrahedral arrangement around

the body center oxide. Draw the unit cell in the empty cube. What is the coordination number and shape around the copper cations, and what is the charge on copper? Do the same analysis for the oxide anions.

Answer: The coordination number of Cu+ is two while the coordination number of O2- is 4

Explanation:

The coordination number of an ion in a unit cell arrangement refers to the number of immediate neighboring ions of opposite charge surrounding a particular ion. In Cu2O, the charge on Cu is +1 and the charge on the oxide ion is -2. Each copper I ion is surrounded by two oxide ions while each oxide ion is surrounded by four copper I ions in each unit cell.

30cm^3 of a dilute solution of Ca(OH)2 required 11 cm^3 of 0.06 mol/dm^. Hcl for complete neutralization. Calculate the concentr
Alenkasestr [34]

Answer: Thus concentration of Ca(OH)_2 in mol/dm^3  is 0.011 and in g/dm^3 is 0.814

Explanation:

To calculate the concentration of Ca(OH)_2, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is HCl

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is Ca(OH)_2

We are given:

n_1=1\\M_1=0.06mol/dm^3\\V_1=11cm^3=0.011dm^3\\n_2=2\\M_2=?\\V_2=30cm^3=0.030dm^3         1cm^3=0.001dm^3

Putting values in above equation, we get:

1\times 0.06mol/dm^3\times 0.011dm^3=2\times M_2\times 0.030dm^3\\\\M_2=0.011mol/dm^3

The concentration in g/dm^3 is 0.011mol/dm^3\times 74g/mol=0.814g/dm^3

Thus concentration of Ca(OH)_2 is 0.011mol/dm^3 and 0.814g/dm^3

3. When aqueous solutions of sodium phosphate (Na3PO4) and chromium(III) chloride (CrCl3) react, chromium(III) phosphate forms a
nignag [31]

The four ionic species initially in solution are Na⁺, PO₄³⁻, Cr³⁺, and Cl⁻. Since the precipitate is composed of Cr³⁺ and PO₄³⁻ ions, the spectator ions must be Na⁺ and Cl⁻.

The complete ionic equation is 3Na⁺(aq) + PO₄³⁻(aq) + Cr₃⁺(aq) + 3Cl⁻(aq) → 3Na⁺(aq) + 3Cl⁻(aq) + CrPO₄(s).

So the balanced <u>net ionic equation</u> for this reaction would be Cr³⁺(aq) + PO₄³⁻(aq) → CrPO₄(s).
