A 300.0 mL saturated solution of copper(II) peroidate, Cu(IO4)2, contains .30 grams of dissolved salt. Calculate Ksp.

Chemistry

Sphinxa [80]2 years ago

Answer:

Ksp=4.9 \times 10^{-8}

Explanation:

balanced chemical reaction:

Cu(IO_4)_2 \rightarrow CU^{2+} +2 IO_4^-

concentration or molarity of Cu(IO4)2= mole/Volume in L

mole=\frac{mass\, given}{molecular\,weight}

mole=\frac{0.30}{445.4}

mole=6.74 \times 10^{-4}

volume= 300 ml=0.3 L

molarity =\frac{mole}{volume\, in\, L}

molarity=2.3\times 10^{-3}

Solubility means maximum salt which can be dissolved.

lets solubility=S

[CU^{2+}]=S;

[IO_4^-] =2S

S=2.3\times 10^{-3}

Ksp=S\times(2S)^2

Ksp=4.9 \times 10^{-8}

4. Why does the metallic character of the alkaline earth metals increase as you go down the
tino4ka555 [31]

As you proceed down the periodic table, the metallic character becomes stronger. This is because as the atomic radius increases, there is less attraction between the nucleus and the valence electrons due to the greater distance between them, making electrons simpler to shed.

The atomic radius of main group elements generally increases down a group because
Pachacha [2.7K]

The atomic radius of main group elements generally increases down a group because as there are more electrons they are farther away from the nucleus and the electrons closer to the nucleus shield the outer electrons from the protons for attraction.

What is the value of for this aqueous reaction at 298 K? <br><br>A+B↽⇀C+D ΔG°=12.86 kJ/mol<br><br>K=
agasfer [191]

Answer:

The equilbrium constant is 179.6

Explanation:

To solve this question we can use the equation:

ΔG = -RTlnK

<em>Where ΔG is Gibbs free energy = 12.86kJ/mol</em>

<em>R is gas constant = 8.314x10⁻³kJ/molK</em>

<em>T is absolute temperature = 298K</em>

<em>And K is equilibrium constant.</em>

Replacing:

12.86kJ/mol = -8.314x10⁻³kJ/molK*298K lnK

5.19 = lnK

e^5.19 = K

179.6 = K

<h3>The equilbrium constant is 179.6</h3>

Consider the following reactions. (Note: (s) = solid, (l) = liquid, and (g) = gas.) ½H2(g) + ½I2(g) → HI(g), ΔH = +6.2 kcal/mole
BARSIC [14]
½H2(g) + ½I2(g) → HI(g) ΔH = +6.2 kcal/mol
or...
½H2(g) + ½I2(g) + 6,2kcal/mole → HI(g)
________
21.0 kcal/mole + C(s) + 2S(s) → CS2(l)
or...

sp2606 [1]

They seem to eat a lot ranging from woody plants to vines, though in the rainforest most of their diet is made up of Malaysia and plant material, to be more specific

So I would go with leaves, 50%

Flowers, buds, and insects, 10%

Fruits, 40%
