mol FeCl₂ = mass : molar mass = 507 : 127 = 3.992

mol NaCl = 2/1 x mol FeCl₂ = 2/1 x 3.992 = 7.984

mass NaCl = 7.984 x 58.5 = 467.06

closest to C. 467.52 g NaCl

507 g of FeCl₂ produced amount of NaCl is equal to 467.52 grams. Therefore, option (C) is correct.

The balanced chemical equation in which the number of atoms of each element is equal on either side of the chemical equation of the reaction.

The law of conservation of mass follows by a balancing of a chemical equation by which the total mass of the reactants must be equal to the total mass of the products.

Given, the balanced chemical reaction of iron (II) chloride and NaOH:

\(FeCl_2 + 2NaOH \longrightarrow Fe(OH)_2(s) + 2NaCl\)

Given, the mass of the FeCl₂= 507 g

The molar mass of FeCl₂ and NaCl is 126.75 g/mol and 58.44 g/mol respectively.

126.75 g of FeCl₂ produced amount of NaCl = 2 × 58.44 g

507 g of FeCl₂ produced NaCl = (116.88/126.75) ×507 = 467.52 g

Answer: Equilibrium

Explanation:

The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.

For a chemical equilibrium reaction, equilibrium state is achieved when the rate of forward reaction becomes equals to rate of the backward reaction which means the products are being made as quickly as reactants

Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.

The balanced reaction is: 2AgCl(s) + 2NO(g) → 2Ag(s) + Cl^-(aq) + 2NO3^-(aq). The standard cell potential (Eo cell) can be calculated by summing the standard reduction potentials of the half-reactions involved in the reaction.

To calculate Eo cell, we need to consider the reduction half-reactions for the species involved in the reaction. The reduction half-reactions are:

1. Reduction of Ag+ to Ag: Ag+(aq) + e^- → Ag(s) (Eo = +0.80 V)

2. Reduction of NO to NO3^-: NO3^-(aq) + 2H+(aq) + e^- → NO(g) + 2H2O(l) (Eo = +0.96 V)

By adding these two half-reactions, we can obtain the overall balanced redox reaction. Since Ag+ and NO3^- are spectator ions, they do not participate in the reaction. Thus, the balanced redox reaction becomes:

2AgCl(s) + 2NO(g) → 2Ag(s) + 2Cl^-(aq) + 2NO3^-(aq)

The standard cell potential (Eo cell) is the sum of the reduction potentials of the half-reactions:

Eo cell = Eo reduction of Ag+ to Ag + Eo reduction of NO to NO3^-

        = (+0.80 V) + (+0.96 V)

        = +1.76 V

Positively charged aluminum ions gain electrons from the cathode and form molten aluminum. Electrolysis is used to perform the extraction. The aluminum oxide must let the ions to travel freely in order for electricity to flow through it.

Due to its extremely high melting point (about 2000°C), aluminum oxide would be expensive to melt. Although it doesn't dissolve in water, aluminum oxide does in molten cryolite. The melting point of this aluminum compound is lower than that of aluminum oxide. Cryolite utilization lowers some of the energy expenses associated with aluminum extraction. Carbon dioxide bubbles off once the oxygen and carbon in the electrodes react. The positive electrodes must consequently be replaced regularly since they lose carbon over time. This raises the price of the procedure.

The oxygen atoms in water (H2O) are less likely to bind metals than their hydrogen counterparts. This is due to the fact that oxygen has a higher attraction for electrons than hydrogen since it is more electronegative than hydrogen.

Hydrogen bonds form between nearby hydrogen and oxygen atoms of adjacent water molecules in the case of water. A bond called a hydrogen bond is produced by the attraction between individual water molecules.

Because oxygen has a stronger affinity for electrons than other atoms, like hydrogen, the electrons are drawn toward the oxygen atom, which in turn attracts hydrogen atoms.

The boiling point of the 3.6 molal solution of ethylene glycol in benzene is 89.208 ºC.

What is Boiling Point?

Boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure, usually atmospheric pressure. At the boiling point, bubbles of vapor are formed throughout the liquid, and the liquid changes phase to become a gas.

The boiling point elevation of a solution is given by the formula:

ΔTb = Kb x molality

Where ΔTb is the boiling point elevation, Kb is the ebullioscopic constant of the solvent, and molality is the molal concentration of the solute.

For benzene, Kb = 2.53 ºC/m.

Since the molality of the ethylene glycol solution is 3.6 molal, we can calculate the boiling point elevation as:

ΔTb = 2.53 ºC/m x 3.6 molal = 9.108 ºC

This means that the boiling point of the solution is 9.108 ºC higher than the boiling point of pure benzene.

To find the boiling point of the solution, we need to add this value to the boiling point of pure benzene, which is 80.1 ºC. Therefore:

Boiling point of solution = 80.1 ºC + 9.108 ºC = 89.208 ºC

, Calculate Frequency

Example #11: What is the frequency of radiation with a wavelength of 5.00 x 10¯8 m? In what region of the electromagnetic spectrum is this radiation?

Solution:

1) Use λν = c to determine the frequency:

(5.00 x 10¯8 m) (x) = 3.00 x 108 m/s

x = 6.00 x 1015 s¯1

2) Determine the electromagnetic spectrum region:

Consult a convenient reference source.

This frequency is right in the middle of the ultraviolet region of the spectrum.

Solution:

a) Use λν = speed:

(x) (256.0 s¯1) = 340.0 m/s

The answer, to four sig figs, is 1.328 m.

Problem #16: Calculate the wavelength of radiation emitted from radioactive cobalt with a frequency of 2.80 x 1020 s¯1. What region of the eletromagnetic spectrum does this lie in?

Solution:

1) Calculate the wavelength:

λν = c

(x) (2.80 x 1020 s¯1) = 3.00 x 108 m/s

x = 1.07 x 10¯12 m

2) Determine the region of the EM spectrum:

Gamma rays.

Problem #17: 1.50 x 1013 Hz? Does this radiation have a longer or shorter wavelength than red light?

Comment: there are a number of ways to answer this question. I'll do two.

Solution #1:

Calculate the frequency of 7000 Å (the longest wavelength of red light):

7000 Å = 7000 x 10¯8 cm = 7.00 x 10¯5 cm (three sig figs is a reasonable assumption)

λν = c

(7.00 x 10¯5 cm) (x) = 3.00 x 1010 cm/s

x = 4.28 x 10¯14 s¯1

A lower frequency (like the value given in the problem) means a longer wavelength. The radiation in the problem has a longer wavelength than the red light I used.

Beyond red on the EM spectrum is infrared.

Solution #2:

Consult a convenient reference source.

Compare 1.50 x 1013 Hz to the various values in the frequency column of the above web site.

Determine that the frequency given in the problem lies in the infrared, a region that has a longer wavelength than red light does.

Problem #18: What color is light whose frequency is 7.39 x 1014 Hertz?

Solution:

The usual manner to solve this problem is to determine the wavelength, then compare the wavelength to a color chart of the electromagnetic spectrum. Here is an example of a color chart. You can find many more on the Internet.

1) Determine wavelength:

λν = c

(x) (7.39 x 1014 s¯1) = 3.00 x 108 m/s

x = 4.065 x 10¯7 m

2) EM color charts usually express the wavelength in nm:

4.065 x 10¯7 m times (109 nm / 1 m)= 406.5 nm

3) When you examine a color chart, you see that the given wavelength is in the violet region.

An alternate method would be to find a color chart which associates frequency values with the colors of the visible spectrum. This type of chart is not as common as a wavelength-based chart, but they can be found. Here is an example.

Using that chart will require that you convert Hz to THz (terahertz).

7.39 x 1014 Hz times ( 1 THz / 1012 Hz) = 739 THz

Problem #19: Calculate the frequency of radiation with a wavelength of 4.92 cm.

Comment: since the wavelength is already in cm, we can use c = 3.00 x 1010 cm s¯1 and not have to do any conversions at all.

Solution:

(4.92 cm) (x) = 3.00 x 1010 cm s¯1

x = 6.10 x 109 s¯1

Problem #20: Calculate the frequency of radiation with a wavelength of 8973 Å.

Comment: since 1 Å = 10¯8 cm, therefore 8973 Å = 8973 x 10¯8 cm. Converting to scientific notation gives 8.973 x 10¯5 cm. This is another place where the cm s¯1 value for c can be used, since Å converts to cm very easily.

Solution:

(8.973 x 10¯5 cm) (x) = 3.00 x 1010 cm s¯1

x = 3.34 x 1014 s¯1

The frequency of the radiation is 6.0 × 10¹⁵ s⁻¹

The radiation is in the Ultra-violet region of the electromagnetic spectrum

From the question,

We are to determine the frequency of radiation with a wavelength of 5.00 × 10⁻⁸ m

From the formula

\(c = \nu \lambda\)

We can write that

\(\nu = \frac{c}{\lambda}\)

Where \(\nu\) is the frequency

\(c\) is the speed of light (\(c = 3.0 \times 10^{8} \ m/s\))

and \(\lambda\) is wavelength

From the given information

\(\lambda = 5.00 \times 10^{-8} \ m\)

∴ \(\nu = \frac{3.0 \times 10^{8} }{5.00 \times 10^{-8} }\)

\(\nu = 6.0 \times 10^{15} \ s^{-1}\)

Hence, the frequency of the radiation is 6.0 × 10¹⁵ s⁻¹
