1.24 grams of magnesium phosphate tribasic dissolved in 1 L of lemon juice. What is the Ksp of the magnesium phosphate tribasic
vivado [14]

<u>Answer:</u> The solubility product of magnesium phosphate tribasic is 2.52\times 10^{-10}

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (in L)}}

Given mass of magnesium phosphate = 1.24 g

Molar mass of magnesium phosphate = 262.85 g/mol

Volume of solution = 1 L

Putting values in above equation, we get:

\text{Molarity of solution}=\frac{1.24g}{262.85g/mol\times 1}\\\\\text{Molarity of solution}=4.72\times 10^{-3}M

The equation for the ionization of the magnesium phosphate is given as:

Mg_3(PO_4)_2\leftrightharpoons 3Mg^{2+}+2PO_4^{3-}

Expression for the solubility product of Mg_3(PO_4)_2 will be:

K_{sp}=[Mg^{2+}]^3[PO_4^{3-}]^2

We are given:

[Mg^{2+}]=(3\times 4.72\times 10^{-3})=1.416\times 10^{-2}M

[PO_4^{3-}]=(2\times 4.72\times 10^{-3})=9.44\times 10^{-3}M

Putting values in above expression, we get:

K_{sp}=(1.416\times 10^{-2})^3\times (9.44\times 10^{-3})^2=2.52\times 10^{-10}

Hence, the solubility product of magnesium phosphate tribasic is 2.52\times 10^{-10}

HELP!!!!!!!!

The<span> pros of using GMO are that they result in higher yields than natural food crops hence able to feed a growing human population on earth. They are also able to withstand crop diseases and pests hence improved yields. </span>

The cons of transgenic plants contribute to antibiotic resistance especially due to the use of antibiotic resistance genes in recombination genes. Another is the environmental impact. GMO may result in uncontrolled gene transfer to natural crops in the environment hence created challenges such as super-weeds.

g n the Ideal Gas Law lab, how is the temperature of the hydrogen gas determined? Select one: The pressure of the gas is determi
Charra [1.4K]

Answer:

The volume of the gas is determined, which will allow you to calculate the temperature.

Explanation:

According to Charles law; the volume of a given mass of an ideal gas is directly proportional to its temperature at constant pressure.

This implies that, when the volume of an ideal gas is measured at constant pressure, the temperature of the ideal gas can be calculated from it according to Charles law.

Hence in the Ideal Gas Law lab, the temperature of an ideal gas is measured by determining the volume of the ideal gas.

Enter the condensed electron configuration for cu4+.express your answer in condensed form, in order of increasing orbital energy
Marysya12 [62]
Electronic Configuration of Cu⁴⁺ is written using these two steps;

Step I:
          Write the Electronic Configuration of Copper (Cu).

As Atomic Number of Cu = 29
So,
                             1s², 2s², 2p⁶, 3s², 3p⁶, 3d¹⁰, 4s¹

Rearranging it in order of increasing orbital energy,

                             1s², 2s², 2p⁶, 3s², 3p⁶, 4s¹, 3d¹⁰
Or,
                            Cu  =   [Ar] 4s¹, 3d¹⁰

Step II:
            Now, the Cu⁴⁺ ion has lost 4 electrons, So one electron from 4s and 3 electrons from 3d orbital are removed, The resulting electronic configuration becomes,
                            Cu⁴⁺  =   [Ar] 3d⁷
