The compound that will react most rapidly with ethyl chloride in the presence of aluminum trichloride is the one that has an electron-donating group in its structure.

The electron-donating group makes the compound more nucleophilic, which means that it is more likely to attack the electrophilic ethyl chloride. Therefore, the compound with the -OH group is most likely to react most rapidly with ethyl chloride in the presence of aluminum trichloride. Expected products of the reaction, an ether will be formed as a result of the reaction between the compound with the -OH group and ethyl chloride in the presence of aluminum trichloride. This is because the reaction involves the substitution of the -OH group with an ethyl group to form the ether.

In an electromagnetic spectrum, bright red light would produce  photoelectric effect on a strip of metal.

The electromagnetic spectrum is made up of waves that convey radiant electromagnetic energy and are comprised of electromagnetic fields. These waves may propagate over space. The electromagnetic waves that make up radiation are coordinated oscillations of the electric and magnetic fields. They develop as a result of periodic shift in both the electric and magnetic fields.

All electromagnetic waves in a vacuum move at the same speed, which is equal to the speed of air. The frequency or wavelength of a radio wave determines where it is located in the electromagnetic spectrum. They are produced when electrically charged particles accelerate and communicate with other charged particles.

Copper has the highest conductivity of any metal used in electronics. The statement is false.

Silver is the element that conducts electricity the best, followed by copper and gold.

The earth's most conductive metal is by far silver. Silver only has one valence electron, which explains this. This one electron can also go about freely and encounter little opposition. As a result, some of the metals with this particular property are silver and copper.

Silver is the metal with the highest thermal and electrical conductivity because of its distinctive crystal structure and lone valence electron.

Since copper is the non-precious metal with the highest conductivity, it has a higher electrical current carrying capacity than other non-precious metals.

The calcium ion has 18 protons, 20 neutrons, and 20 electrons.
The relationship between the components a and b is Inverse proportion.


The calcium ion (Ca2+) has a 2+ charge, indicating that it has lost 2 electrons from its neutral state. To determine the number of protons, neutrons, and electrons in the calcium ion, we need to consider its atomic number and mass.

The atomic number of calcium is 20, which indicates that it has 20 protons. Since the calcium ion has a 2+ charge, it means it has lost 2 electrons. Therefore, the number of electrons in the calcium ion is 20 - 2 = 18.

The mass number of calcium is 40 amu, which represents the total number of protons and neutrons. Since the calcium ion has 20 protons, the number of neutrons can be calculated as 40 - 20 = 20.

So, the correct option is: d. 18 protons, 20 neutrons, and 20 electrons

In the expression a∼1/b, the relationship between the components a and b is an inverse proportion. This means that as the value of a increases, the value of b decreases, and vice versa.

The correct option is $26785.To calculate the total cost per equivalent unit using the weighted average method, we need to consider the costs incurred in both the beginning work in process and the units added during the period.

First, let's calculate the equivalent units of production for both conversion and materials:

Conversion costs:

Beginning work in process: 400 units × 20% complete = 80 equivalent units

Units added during the period: 2,000 units × 40% complete = 800 equivalent units

Total equivalent units for conversion = 80 + 800 = 880 equivalent units

Material costs:

Beginning work in process: 400 units × 30% complete = 120 equivalent units

Units added during the period: 2,000 units × 50% complete = 1,000 equivalent units

Total equivalent units for materials = 120 + 1,000 = 1,120 equivalent units

Next, let's calculate the total costs incurred:

Conversion costs:

Beginning work in process cost: $14,880

Costs added during the period: $409,200

Total conversion costs = $14,880 + $409,200 = $424,080

Material costs:

Beginning work in process cost: $9,900

Costs added during the period: $180,080

Total material costs = $9,900 + $180,080 = $189,980

Now, we can calculate the total cost per equivalent unit:

Total cost per equivalent unit = (Total conversion costs + Total material costs) / (Total equivalent units for conversion + Total equivalent units for materials)

Total cost per equivalent unit = ($424,080 + $189,980) / (880 + 1,120)

Total cost per equivalent unit ≈ $267.85

Therefore, the correct option is $26785.

The percent yield for the reaction is 84.6%.

To calculate the percent yield for the reaction, we first need to determine the theoretical yield of CO₂ based on the balanced chemical equation for the reaction:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

From the equation, we can see that for every mole of C₃H₈ , 3 moles of CO₂ are produced. So, to determine the theoretical yield of CO2, we need to first convert the mass of C₃H₈ to moles and then multiply that by the stoichiometric ratio for CO₂.

The molar mass of C₃H₈ is 44.1 g/mol, so:

3.66 g C₃H₈ / 44.1 g/mol = 0.083 mol C₃H₈

Using the stoichiometry of the reaction, we can now calculate the theoretical yield of CO₂:

0.083 mol C₃H₈ × 3 mol CO₂ / 1 mol C₃H₈ = 0.25 mol CO₂

And the theoretical mass of CO₂:

0.25 mol CO₂ × 44.01 g/mol = 11.0025 g CO₂

Finally, the percent yield of the reaction can be calculated as:

9.31 g CO₂ / 11.0025 g CO₂ × 100% = 84.6%
