The given question is incomplete. The complete question is:

When 282. g of glycine (C2H5NO2) are dissolved in 950. g of a certain mystery liquid X, the freezing point of the solution is 8.2C lower than the freezing point of pure X. On the other hand, when 282. g of ammonium chloride are dissolved in the same mass of X, the freezing point of the solution is 20.0C lower than the freezing point of pure X. Calculate the van't Hoff factor for ammonium chloride in X.

Answer:  the van't Hoff factor for ammonium chloride is 1.74

Explanation:

Depression in freezing point is given by:

[tex]\Delta T_f=i\times K_f\times m[/tex]

[tex]\Delta T_f=T_f^0-T_f=8.2^0C[/tex] = Depression in freezing point  

[tex]K_f[/tex] = freezing point constant = ?

i = 1 ( for non electrolyte)

m= molality

[tex]8.2^0C=1\times K_f\times \frac{\text{mass of solute}}{\text{molar mass of solute}\times \text{weight of solvent in kg}}[/tex]

Weight of solvent (X)= 950 g = 0.95 kg

Molar mass of solute (glycine) = 75.07 g/mol

Mass of solute (glycine) = 282 g

[tex]8.2^0C=1\times K_f\times \frac{282g}{75.07g/mol\times 0.95kg}[/tex]

[tex]K_f=2.07[/tex]

ii) [tex]20.0^0C=i\times \times \frac{\text{mass of solute}}{\text{molar mass of solute}\times \text{weight of solvent in kg}}[/tex]

Weight of solvent (X)= 950 g = 0.95 kg

Molar mass of solute (ammonium chloride) = 53.49 g/mol

Mass of solute (ammonium chloride) = 282 g

[tex]20.0^0C=i\times 2.07\times \frac{282g}{53.49g/mol\times 0.95kg}[/tex]

[tex]i=1.74[/tex]

Thus the van't Hoff factor for ammonium chloride is 1.74

Answer:

Since energy can’t be created or destroyed, and water loses potential energy when it freezes to form ice. The energy remains electrical but then changes to kinetic when Enough energy is released.

Explanation:

The excess electrical energy gained by water during ice forming process is removed as potential energy to maintain law of conservation of energy.

According to the principle of conservation of energy, energy can neither be created nor destroyed but can transformed from one form to energy.

The electrical energy used by the ice maker to freeze water works on the same principle of conservation of energy.

Thus, the excess electrical energy gained by water during ice forming process is removed as potential energy to maintain law of conservation of energy.

Explanation:

A carbon atom is an element that can be found in the atomic number 6th of the periodic table. It electronic configuration is 1s² 2s² 2p². It is a tetravalent and non metallic compound. In its outermost structure, Carbon needs four additional valence electrons to complete its octet structure. That is why hydrogen with only one electron can be bonded to one carbon atom in four different places making the carbon element obtain a tetrahedral shape.

Answer: An object's gravitational force depends primarily on the object's mass.

Explanation:

According to the Universal law of gravitation, every object whether is it is having large r small mass tends to exert a force on every other object, therefore this force is known as gravitational force.

Formula to calculate gravitational force is as follows.

[tex]F = \frac{G \times m_{1} \times m_{2}}{r^{2}}[/tex]

where,

F = Gravitational force

G = Gravitational constant = [tex]6.674 \times 10^{-11} m^{3}/kg s^{2}[/tex]

[tex]m_{1}[/tex] = mass of object 1

[tex]m_{2}[/tex] = mass of object 2

r = distance between the centers of the objects

Therefore, it means that gravitational force of an object primarily depends on an object's mass.

Thus, we can conclude that an object's gravitational force depends primarily on the object's mass.

Answer:

4.7 atm

Explanation:

From the question given above, the following data were obtained:

Total pressure (P) = 15.3 atm

Pressure of Helium, P(He) = 3.2 atm

Pressure of Oxygen, P(O) = 7.4 atm

Pressure of Argon, P(Ar) =?

The pressure of Argon, P(Ar) in the tank can be obtained as illustrated below:

P = P(He) + P(O) + P(Ar)

15.3 = 3.2 + 7.4 + P(Ar)

15.3 = 10.6 + P(Ar)

Collect like terms

15.3 – 10.6 = P(Ar)

4.7 = P(Ar)

P(Ar) = 4.7 atm

Therefore, the pressure of Argon, P(Ar) in the tank is 4.7 atm

Answer:

101.6ml

Explanation:

Using the formula;

CaVa = CbVb

Where;

Ca = concentration of acid (M)

Cb = concentration of base (M)

Va = volume of acid (ml)

Vb = volume of base (ml)

Based on the information as follows:

Ca = 2.5M

Cb = 1.23M

Va = 50ml

Vb = ?

Using CaVa = CbVb

2.5 × 50 = 1.23 × Vb

125 = 1.23Vb

Vb = 125/1.23

Vb = 101.6ml

Answer:

25.1 g

Explanation:

Step 1: Write the balanced decomposition reaction

2 HBr(aq) ⇒ H₂(g) + Br₂(l)

Step 2: Calculate the moles corresponding to 24.7 g of Br₂

The molar mass of Br₂ is 159.81 g/mol.

24.7 g × 1 mol/159.81 g = 0.155 mol

Step 3: Calculate the moles of HBr needed to produce 0.155 moles of Br₂

The molar ratio of HBr to Br₂ is 2:1. The moles of HBr needed are 2/1 × 0.155 mol = 0.310 mol.

Step 4: Calculate the mass corresponding to 0.310 moles of HBr

The molar mass of HBr is 80.91 g/mol.

0.310 mol × 80.91 g/mol = 25.1 g

Explanation:

Depression in Freezing point

= Kf × i × m

where m is molality , i is Van't Hoff factor, m = molality

Since molality and Kf remain the same

depression in freezing point is proportional to i

i= 2 for CuSO4 ( CuSO4----------> Cu+2 + SO4-2

i=1 for C2h6O

i= 3 for MgCl2 ( MgCl2--------> Mg+2+ 2Cl-)

So the freezing point depression is highest for MgCl2 and lowest for C2H6O

so freezing point of the solution = freezing point of pure solvent- freezing point depression

since MgCl2 has got highest freezing point depression it will have loweest freezing point and C2H6O will have highest freezing point

Magnesium nitride, Mg₃N, is a binary salt. Upon heating, it decomposes into magnesium metal and nitrogen gas. The unbalanced equation is:

Mg₃N(s) ⇒ Mg(s) + N₂(g)

We can balance it with the trial and error method. First, we will balance N atoms by multiplying Mg₃N by 2.

2 Mg₃N(s) ⇒ Mg(s) + N₂(g)

Then, we get the balanced equation by multiplying Mg by 6.

2 Mg₃N(s) ⇒ 6 Mg(s) + N₂(g)

[tex]Ksp=5.20x10^{-6}[/tex]

Explanation:

Hello there!

In this case, according to the solubility equilibrium of calcium hydroxide:

[tex]Ca(OH)_2\rightleftharpoons Ca^{2+}+2OH^-[/tex]

Whereas the equilibrium expression is:

[tex]Ksp=[Ca^{2+}][OH^-]^2[/tex]

It is firstly necessary to calculate the molar solubility given the grams and volume of the dissolved solute:

[tex]s=\frac{0.186g/(74.09g/mol)}{0.230L}=0.0109M[/tex]

Now, according to the Ksp expression, we plug in s as the solubility to obtain:

[tex]Ksp=(s)(2s)^2\\\\Ksp=(0.109)(2*0.0109)^2\\\\Ksp=5.20x10^{-6}[/tex]

Regards!

According to the solution equilibrium,

Now,

The molar solubility will be:

→ [tex]s = \frac{\frac{0.186}{74.09} }{0.230}[/tex]

     [tex]= 0.0109 \ M[/tex]

hence,

The Ksp value will be:

→ [tex]Ksp = (s)(2s)^2[/tex]

By substituting the values,

          [tex]= (0.109)(2\times 0.0109)^2[/tex]

          [tex]= 5.20\times 10^{-6}[/tex]

The correct answer is

C. -1108.7 kJ/mol rxn

From the table values, the standard Gibbs free energy change for the formation of POCl₃ is -1108.7 kJ/mol

We can calculate ΔG° for the reaction using the following formula:

ΔG° = ΣnΔG°f(products) - ΣnΔG°f(reactants)

where ΔG°f is the standard Gibbs free energy of formation for each compound and n is the stoichiometric coefficient of each compound in the balanced chemical equation.

We can look up the values of ΔG°f for each compound in tables of thermodynamic data. At standard conditions (25°C and 1 atm pressure), the values are:

ΔG°f (POCl₃) = -558.9 kJ/mol

ΔG°f (P₂) = 0 kJ/mol

ΔG°f (O₂) = 0 kJ/mol

ΔG°f (Cl₂) = 0 kJ/mol

Plugging these values into the formula, we get:

ΔG° = (2 mol)(-558.9 kJ/mol) - (1 mol)(0 kJ/mol) - (1 mol)(0 kJ/mol) - (3 mol)(0 kJ/mol)

ΔG° = -1117.8 kJ/mol

Therefore, the correct option  is C. -1108.7 kJ/molrxn. Note that this answer differs slightly from the calculated value because the given choices are rounded to one decimal place.
