predict which aqueous solution will have the lowest freezing point

A. 0.25MOL/LITER SUCROSE
B. 0.15 MOL/LCaCl2
C. 0.15MOL/LNaCl
D. 0.2MOL/LNaNO3

Answers

Answer 1

CaCl₂ has lowest freezing point as it has higher "im" value.

What is freezing point?

A solution's freezing point is lower than that of the pure solvent's. It follows that freezing cannot happen until a solution is lowered to a temperature lower than the pure solvent.

As we know more "im" value lowest is the freezing point.

Here,

m = molarity

i = van't Hoff factor = 1 + (n-1) α

α = degree of ionization

n = number of ions.

A. 0.25 MOL /LITER SUCROSE = 0.25 M SUCROSE

m = 0.25 M

Sucrose is non-electrolyte, so α = 0

or, i = 1 + (n-1) × 0

or, i = 1

So, im = 1 × 0.25 M

im = 0.25 M

B.  0.15 MOL/L CaCl₂ = 0.15 M CaCl₂

m = 0.15 M

CaCl₂ → Ca⁺² + 2Cl⁻

no. of ions (n) = 3

CaCl₂ is electrolyte, so α = 1

Thus,  i = 1 + (3-1) × 1

or, i = 3

So, im = 3 × 0.15 M

or, im = 0.45 M

C. 0.15 MOL/L NaCl = 0.15 M NaCl

m = 0.15 M

NaCl → Na⁺ + Cl⁻

no. of ions = 2

NaCl is electrolyte, so α = 1

Thus,  i = 1 + (2-1) × 1

or, i = 2

So, im = 2 × 0.15 M

or, im = 0.30 M

D. 0.2 MOL/L NaNO₃ = 0.2 M  NaNO₃

m =  0.2 M

NaNO₃ → Na⁺ + NO₃⁻

no. of ions = 2

NaNO₃ is electrolyte, so α = 1

Thus,  i = 1 + (2-1) × 1

or, i = 2

So, im = 2 × 0.2 M

or, im = 0.40 M

Among these four aqueous solution, CaCl₂ has higher "im" value thus it has lowest freezing point.

What is the pressure in a 19.1 L cylinder filled with 0.684 mol of nitrogen gas at a temperature of 326 K ?

Answers

Answer:

The hydrogen sample has a pressure of 0.957 atmospheres.

Explanation:

Let consider that the hydrogen sample behaves ideally, the equation of state for ideal gases is:

\(P\cdot V = n\cdot R_{u}\cdot T\) (1)

Where:

\(P\) - Pressure, in atmospheres.

\(V\) - Volume, in liters.

\(n\) - Molar quantity, in moles.

\(T\) - Temperature, in Kelvin.

\(R_{u}\) - Ideal gas constant, in atmosphere-liters per mole-Kelvin.

If we know that \(V = 19.1\,L\), \(n = 0.684\,mol\), \(T = 326\,K\) and \(R_{u} = 0.082\,\frac{atm\cdot L}{mol\cdot K}\), then the pressure of the hydrogen sample is:

\(P = \frac{n\cdot R_{u}\cdot T}{V}\)

\(P = \frac{(0.684\,mol)\cdot \left(0.082\,\frac{atm\cdot L}{mol\cdot K} \right)\cdot (326\,K)}{19.1\,L}\)

\(P = 0.957\,atm\)

The hydrogen sample has a pressure of 0.957 atmospheres.

The mass of \(O_2\) needed to produce 8.65 x \(10^{23\) atoms of silver is 22.96 grams.

Stoichiometric calculation

In the given balanced equation, it is stated that 2 moles of \(Ag_2O\) produce 4 moles of Ag and 1 mole of \(O_2\).

First, let's calculate the number of moles of Ag:

8.65 x \(10^{23\) atoms of Ag / (6.022 x \(10^{23\) atoms/mol) = 1.435 moles of Ag

Since 2 moles of  \(Ag_2O\) produce 1 mole of  \(O_2\), the number of moles of  \(O_2\) needed is half of the moles of  \(Ag_2O\).

Number of moles of  \(O_2\)= 1.435 moles of  \(Ag_2O\) / 2 = 0.7175 moles

Now, we'll use the molar mass of  \(O_2\) to find the mass:

Molar mass = 32.00 g/mol

Mass of  \(O_2\) = number of moles × molar mass

                   = 0.7175 moles × 32.00 g/mol = 22.96 g

Therefore, the mass of  \(O_2\) needed to produce 8.65 x \(10^{23\) atoms of silver is 22.96 grams.

how is it possible to have two ionic solids made of 1/-1 ions, yt the compounds have different crystal lattice energies

Answers

The crystal lattice energy depends not only on the charge of the ions but also on the distance between the ions and the arrangement of the ions in the crystal structure.

Therefore, two ionic solids made of 1/-1 ions can have different crystal lattice energies if the ions have different sizes or if the arrangement of the ions in the crystal is different. A crystal lattice is a three-dimensional arrangement of atoms, ions, or molecules in a crystal that forms a regular repeating pattern. It is a fundamental concept in solid-state physics and chemistry, and understanding the crystal lattice structure of a material is essential for predicting its properties and behavior. The crystal lattice is described by its unit cell, which is the smallest repeating unit of the lattice that can be used to build the entire crystal structure. The crystal lattice energy is the amount of energy required to break the lattice and is influenced by the size and charge of the ions, as well as the arrangement of the ions in the crystal structure.

Answers

Answer:

The statements that are true about unstable isotopes are:

They are radioactive.

They have an imbalance between protons and neutrons.

They may decompose.

Explanation:

An isotope is an atom that has the same number of protons as other atoms of the same element but a different number of neutrons. Some isotopes are stable, meaning they do not undergo any changes over time, while others are unstable or radioactive.

Unstable isotopes have an imbalance between the number of protons and neutrons in the nucleus, which makes them unstable and prone to breaking apart or decomposing. This process is called radioactive decay, and it can result in the emission of alpha or beta particles, gamma radiation, or other forms of energy.

The instability of the nucleus is due to the strong nuclear force that holds the nucleus together, which is overcome by the electrostatic repulsion between the protons. As a result, unstable isotopes are constantly trying to reach a more stable state by releasing energy in the form of radiation.

Because unstable isotopes can decompose, they have a limited lifespan, and their half-lives can vary from fractions of a second to billions of years. This property of unstable isotopes makes them useful in many fields, including medicine, geology, and nuclear energy.

is CF3Cl a polar or non-polar molecule?

Answers

Answer: Polar

Explanation: This is because if you look up the Lewis Dot structure of this specific molecule, it will have some net dipole moment, which makes it polar.

It can be considered that when a molecule does have some net dipole moment, it is polar.

So, yes CF3Cl is polar.

CF₃Cl, also known as chlorotrifluoromethane, is a polar molecule.

To determine the polarity of a molecule, consider the individual bond polarities and the molecular geometry.

In CF₃Cl, there is a difference in electronegativity between carbon (C) and chlorine (Cl), as well as between carbon and fluorine (F). Chlorine and fluorine are more electronegative than carbon, meaning they have a greater ability to attract electrons toward themselves.

The C-Cl bond and the C-F bonds in CF₃Cl are polar bonds due to the electronegativity difference. The Cl and F atoms pull the shared electrons towards themselves, creating partial negative charges on those atoms and partial positive charges on the carbon atom.

So far my incorrect answers have been:
0.28
0.798
0.178
0.142
0.881
0.61
and 0.812

Answers

Answer:

The cell potential for the given galvanic cell is 0.188 V.

Explanation:

To calculate the cell potential, we can use the Nernst equation:

Ecell = E°cell - (RT/nF)ln(Q)

where E°cell is the standard cell potential, R is the gas constant (8.314 J/mol·K), T is the temperature in Kelvin (25°C = 298 K), n is the number of moles of electrons transferred (in this case, n = 2), F is the Faraday constant (96,485 C/mol), and Q is the reaction quotient.

First, we need to write the half-reactions and their standard reduction potentials:

Sn4+(aq) + 2e- → Sn2+(aq) E°red = 0.15 V

Fe3+(aq) + e- → Fe2+(aq) E°red = 0.77 V

The overall reaction is the sum of the half-reactions:

Sn2+(aq) + 2Fe3+(aq) → Sn4+(aq) + 2Fe2+(aq)

The reaction quotient Q can be expressed as:

Q = [Sn4+][Fe2+]^2 / [Sn2+][Fe3+]^2

Substituting the given concentrations, we get:

Q = (0.00655)(0.01139)^2 / (0.0624)(0.0437)^2 = 0.209

Now we can calculate the cell potential:

Ecell = 0.15 V + 0.0592 V log([Fe2+]^2/[Fe3+]) + 0.0592 V log([Sn4+]/[Sn2+])

= 0.15 V + 0.0592 V log(0.01139^2/0.0437^2) + 0.0592 V log(0.00655/0.0624)

= 0.188 V

Therefore, the cell potential for the given galvanic cell is 0.188 V.

The cell potential for the given galvanic cell in which the given reaction occurs at 25 °C is 0.188 V.

How to the cell potential of galvanic cell?

To find the cell potential, we take the Nernst equation:

Ecell = E°cell - (RT/nF)ln(Q)

In which R is the gas constant (8.314 J/mol·K) and E° cell is the standard cell potential.

T temperature in Kelvin (25°C = 298 K), and n is the number of moles of electrons transferred (n = 2), Q is the reaction quotient and F is the Faraday constant (96,485 C/mol).

Firstly, write the half-reactions and then their standard reduction potentials:

Sn⁴⁺(aq) + 2e⁻  → Sn²⁺(aq) E°red = 0.15 V

Fe³⁺(aq) + e⁻ → Fe²⁺(aq) E°red = 0.77 V

The overall reaction is the sum of the half-reactions:

Sn²⁺(aq) + 2Fe³⁺(aq) → Sn⁴⁺(aq) + 2Fe²⁺(aq)

The Q reaction quotient can be written as:

Q = [Sn⁴⁺][Fe²⁺]² ÷ [Sn²⁺][Fe²⁺]²

Substituting the given concentrations, we observe:

Q = (0.00655)(0.01139)² ÷ (0.0624)(0.0437)² = 0.209

Next, we can find the cell potential:

Ecell = 0.15 V + 0.0592 V log([Fe²⁺]²/[Fe³⁺]) + 0.0592 V log([Sn⁴⁺]/[Sn²⁺])

= 0.15 V + 0.0592 V log(0.01139²÷0.0437²) + 0.0592 V log(0.00655÷0.0624)

= 0.188 V

Thus, the cell potential for the given galvanic cell is 0.188 V.
