Answer:

1.457*10^-8 grams

Explanation:

First we want to find the molar concentration of MgF2. We can do this by dividing 0.016 (the solubility in grams of MgCl2 in a litre of water) by its molar mass (approx. 62.3 grams). Thus, the molar solubility of MgF2 is 2.57*10^-4 M.

Next, we must calculate the Ksp of MgF2. The equilibrium expression is:

MgF2⇄Mg+2F

Thus   [tex]Ksp=[Mg^+][F^-]^2[/tex]

This means that, in equilibrium, there are 2.57*10^-4 M of [tex]M^+[/tex] and 5.136*10^-4 M of [tex]F^-[/tex]

Plugging in the above information, our Ksp for MgF2 is approximately 6.78*10^-11

Next we will need to use the RICE table. Since there is already 0.29M of NaF dissolved, there is initially 0.29M of [tex]F^-[/tex].

R: MgF2 ⇄ [tex]Mg^{+}[/tex]+2[tex]F^-[/tex]

I:    N/A        0     0.29M

C:   N/A         +x      +x

--------------------------------------------

E:   N/A         x     0.29+x  

To make calculations easier, we will assume that 0.29+x≈0.29

This means that Ksp=0.29x=6.78*10^-11

Therefore, x≈2.338*10^-10M

Multiply that by 62.3 and we get around 1.457*10^-8 grams.

the following question for the mixing of gaseous hydrogen chloride with water to make hydrochloric acid. HCl) + H2O(2) → H30*) + Cl (2) What is the phase label on HCI? aq

       In chemistry and biology, hydrolysis refers to a twofold decomposition reaction in which water participates.

       HCl's conjugate base is Cl in the reaction HCl+H2O+H3O++.

       An acidic solution is created when hydrogen chloride gas and water interact. The reaction's equation is displayed. Cl - + H3O + HCl + H2O

        Hydroxide ion is base 2, and its conjugate acid (water) is acid1. Acid1 is HCl, and its conjugate base is base1.

        The conjugate base of hydrochloric acid is the chloride ion. The hydroxide ion's conjugate acid is water

        H3 O+1 is the conjugate acid of H2 O. The electrical charge on water increases by one when one hydrogen ion is added. Hydrogen is also known as H3 O+1.

       In a reversible chemical reaction, H 2O and HCl join upon contact to create hydronium cations [H 3O] + and chloride anions Cl : HCl + H 2O [H 3O] + + Cl. The resulting mixture is a potent acid known as hydrochloric acid.

Explanation:

When 2 moles of sodium hydroxide (NaOH) reacts with 1 mole of phosphoric acid (H3PO4) it gives 1 moles disodium phosphate Na2HPO4 and 2 moles of water.

0.5 molar solution indicates half moles of molecules are present in per ltr solution.

to prepare disodium phosphate you need to dilute phosphoric acid solution to 0.25 molar and add equal quantity of 0.5 molar solution.

Answer:

9.03*10^23 molecules CH4

Explanation:

In the equation CH4 + O2 -> CO2 + 2H2O, the molar ratio of CH4 to CO2 is 1:1. It takes 1 mole of CH4 burned to form 1 mole of CO2. If we convert molecules to moles, we do 9.03 x 10^23 divided by 6.02 x 10^23 = 1.5 moles of CO2. Since we know the ratio is 1:1, that meant it would take 1.5 moles of CH4 burned to make that much CO2. So we convert our 1.5 moles of CH4 into molecules by multiplying 1.5 * 6.02 x 10^23 which equals 9.03*10^23 molecules CH4.

Answer:

46024 j    or    46.024 kj

Explanation:

500 gm * 4.184 j/(gm-C)  * 22 C = 46024 j

The heat energy absorbed by water of mass 500 g and specific heat capacity of 4.184 J/°Cg with a temperature rise to 22 degree celsius is 46024 J.

Specific heat capacity of a substance is the heat energy required to raise the temperature of that substance by one degree celsius per mole. It is an intensive property and does not dependent on the total amount if the substance.

Specific heat capacity of a substance is a constant and water have this value of 4.184 J/°Cg. The heat energy q absorbed or evolved from a system is related to the specific heat capacity C , mass M and temperature change ΔT occured on the system as in equation written below:

q = mC  ΔT .

The heat energy of water of mass 500 g absorbed for a temperature change of 22 °C can be calculated as follows:

q = 500 g × 22 °C × 4.184 J/°Cg

  =  46024 J.

Hence, the total heat of absorption of water for the given mass and temperature change is 46024 J.

Explanation:

1.0 L * 4 = 4L volume that the gas can occupy at 100 degree Celsius

Explanation:

The intermolecular forces present in the bonding of CH₃F are dipole-dipole interactions and London dispersion forces.

1.) No, CH₃F does not exhibit hydrogen bonding. Hydrogen bonding occurs when a hydrogen atom is bonded to a highly electronegative atom such as fluorine, oxygen, or nitrogen. In CH₃F, the hydrogen atom is bonded to carbon, which is not highly electronegative.

2.) Yes, CH₃F exhibits dipole-dipole interactions. Dipole-dipole interactions occur between molecules that have permanent dipoles due to the electronegativity difference between the atoms. In CH₃F, the fluorine atom is more electronegative than the carbon and hydrogen atoms, resulting in a polar molecule with a permanent dipole moment.

3.) Yes, CH₃F exhibits London dispersion forces. London's dispersion forces, also known as Van der Waals forces, are present in all molecules and arise from temporary fluctuations in electron distribution. Although CH₃F has dipole-dipole interactions, it also experiences London dispersion forces due to the temporary shifts in electron density.

Hence, the bonding in CH₃F was explained above.
