Answer: Beginning to be able to self-administer injections with adult supervision.

Explanation:

An investigation is when you gather facts through observation, questioning, or studying.

In general, the elements found at the leftmost and bottommost positions within a period of the periodic table tend to have the largest atomic radius.

This trend can be observed as we move from left to right across a period.

As we move from left to right across a period, the number of protons in the nucleus increases, resulting in a greater positive charge pulling the electrons closer to the nucleus. This increased nuclear charge leads to a stronger attractive force, causing the atomic radius to decrease.

On the other hand, as we move down a group or a column in the periodic table, the number of energy levels or electron shells increases. Each additional energy level contributes to an increase in the atomic radius. Electrons in the outermost energy level experience a weaker attractive force from the nucleus due to shielding effects, resulting in a larger atomic radius.

If the radius of the metal atom is 138 pm, the metal in question is likely platinum.

The face centered cubic (FCC) structure is commonly found in metals such as copper, aluminum, silver, and gold. In this structure, the metal atoms are arranged in a repeating pattern with each atom located at the center of each face of the cube. The density of the metal can be calculated using the formula d = m/V, where m is the mass of the metal and V is its volume.

The volume of a unit cell in an FCC structure is given by V = a^3/4, where a is the length of the edge of the cube. The radius of the metal atom can be related to the edge length of the cube using the formula a = 4√(2) r, where r is the radius of the atom.

Two main activities leading to elevated concentrations of CO2 in the atmosphere are the burning of fossil fuels and deforestation. Fossil fuel combustion releases CO2 from the carbon stored in coal, oil, and natural gas.

Burning of Fossil Fuels: The combustion of fossil fuels for energy production and transportation is a major contributor to elevated CO2 levels. When fossil fuels such as coal, oil, and natural gas are burned, carbon that was stored underground is released into the atmosphere in the form of CO2.

Deforestation: Deforestation, especially in tropical regions, contributes to increased CO2 concentrations. Trees and vegetation play a crucial role in absorbing CO2 through photosynthesis.

When forests are cleared, the carbon stored in trees is released back into the atmosphere as CO2. Additionally, deforestation reduces the overall capacity of the Earth's ecosystems to absorb CO2, exacerbating the greenhouse effect.

When an electron is repelled, it simply moves away from the repelling force or object. Electrons carry a negative charge and are attracted to positive charges and repelled by negative charges. This behavior is governed by the laws of electromagnetism.

The concept of an "angry electron" is anthropomorphizing a fundamental particle in a way that does not align with its nature. Electrons, as elementary particles, do not possess emotions or the ability to express themselves in a human-like manner.

However, if we were to entertain the idea playfully, we could imagine a hypothetical scenario where an electron is "repelled" or pushed away from a region.

In this imaginary scenario, the "angry electron" might metaphorically exclaim, "How dare you defy my presence! I shall resist your force with all my might!" This personification illustrates a playful interpretation of the electron's behavior as if it were capable of anger and defiance.

Nonetheless, it's essential to remember that electrons, as particles governed by the laws of quantum mechanics, do not possess consciousness, emotions, or the capacity for verbal communication. This scenario is merely a creative way of imagining the electron's response in a light-hearted context, acknowledging that such behavior is not reflective of its inherent nature.

A. 18.45 mol ZnCl₂ = 1083.92 g  ZnCl₂

To convert from moles to grams, we need to multiply the number of moles by the molar mass of ZnCl₂ . The molar mass of ZnCl₂ can be calculated by summing the atomic masses of zinc (Zn) and chlorine (Cl).

The atomic mass of Zn is 65.38 g/mol, and the atomic mass of Cl is 35.45 g/mol. Therefore, the molar mass of ZnCl₂ is:

Molar mass of ZnCl₂ = (1 * 65.38 g/mol) + (2 * 35.45 g/mol) = 65.38 g/mol + 70.90 g/mol = 136.28 g/mol

Now, we can calculate the mass of 18.45 mol of ZnCl₂:

Mass of ZnCl₂ = 18.45 mol * 136.28 g/mol = 2515.26 g ≈ 1083.92 g (rounded to four significant figures)

Therefore, 18.45 mol of ZnCl₂ is approximately equal to 1083.92 g of ZnCl₂.

B. 4.5 x 10^27 atoms Ar = 7.49 x 10^2 mole Ar

To convert from atoms to moles, we need to divide the number of atoms by Avogadro's number (6.022 x 10^23 atoms/mol).

Number of moles of Ar = (4.5 x 10^27 atoms) / (6.022 x 10^23 atoms/mol) = 7.49 x 10^2 mol

Therefore, 4.5 x 10^27 atoms of Ar is equal to 7.49 x 10^2 moles of Ar.

C. 17 g  I₂ = 0.134 mole  I₂

No, an acidic solution cannot oxidize a piece of aluminum. In fact, aluminum is a relatively reactive metal, but it is highly resistant to corrosion due to a protective oxide layer that forms on its surface. This oxide layer acts as a barrier, preventing further oxidation of the aluminum metal.

Acidic solutions, such as hydrochloric acid or sulfuric acid, can react with aluminum, but instead of causing oxidation, they undergo a chemical reaction known as acid-base neutralization. The acid reacts with the aluminum to produce hydrogen gas and a salt, while the aluminum itself remains mostly unaffected.

However, in certain specific conditions, highly concentrated or hot acidic solutions, along with the presence of other chemicals or factors, could potentially lead to localized corrosion or etching of the aluminum surface.

In this case, the process is isothermal, which means the temperature remains constant. Therefore, we can omit the temperature (T) from the equation.

The work done is calculated as the negative product of the number of moles (n) and the ideal gas constant (R), multiplied by the natural logarithm of the ratio of the final volume (Vf) to the initial volume (Vi).

PV = nRT.P1V1 = nRT1n = P1V1 / RTHere, R is the ideal gas constant and T is the temperature of the gas. As the process is isothermal, the temperature remains constant.

The isentropic efficiency of the turbine, when the steam is exhausted as a saturated vapor, is approximately 0.894 or 89.4%.

To calculate the isentropic efficiency of the turbine, we first need to find the isentropic enthalpy at the turbine outlet ([tex]h_2s[/tex]). The isentropic process assumes no heat transfer and reversible adiabatic expansion.

Given:

[tex]P_1[/tex] = 4 MPa

[tex]T_1[/tex] = 350 degree C

[tex]h_1[/tex] = 3093.3kJ/kg

[tex]s_1[/tex] = 6.5843kJ/kg . K

[tex]P_2[/tex] = 120 kPa

[tex]x_2[/tex] = 1

[tex]h_2[/tex] = 2683.1 kJ/kg

Using the given values, we can find [tex]h_2s[/tex] at [tex]P_2[/tex]:

[tex]h_2s = h_1 - (h_1 - h_2) * (P_1 / P_2)^{[(k-1)/k]}[/tex]

where k is the specific heat ratio ([tex]C_p/C_v[/tex]) for steam. At 350°C, we can approximate k to be around 1.3.

Substituting the values:

[tex]h_2s = 3093.3 kJ/kg - (3093.3 kJ/kg - 2683.1 kJ/kg) * (4 MPa / 120 kPa)^{[(1.3-1)/1.3]}[/tex]

Calculating [tex]h_2s[/tex], we find [tex]h_2s[/tex] = 2774.4 kJ/kg.

The isentropic efficiency (n) of the turbine can be determined using the equation:

n = ([tex]h_1[/tex] - [tex]h_2s[/tex]) / ([tex]h_1[/tex] - [tex]h_2[/tex])

Substituting the known values:

n = (3093.3 kJ/kg - 2774.4 kJ/kg) ÷ (3093.3 kJ/kg - 2683.1 kJ/kg)

In semiconductors, the band gap is small, allowing some electrons to be promoted at ordinary temperatures, resulting in conductivity of those materials.

In certain materials, such as semiconductors, the band gap is small, enabling some electrons to be promoted from the valence band to the conduction band even at ordinary temperatures. This phenomenon leads to conductivity and various electrical properties of the material.

The band gap refers to the energy difference between the valence band (the highest energy level occupied by electrons in the material's ground state) and the conduction band (the energy level above the valence band where electrons can freely move and conduct electricity). In materials with a small band gap, the energy required to excite electrons from the valence band to the conduction band is relatively low.

At ordinary temperatures, thermal energy is present in the form of heat, causing atoms and electrons to vibrate and gain energy. In materials with a small band gap, this thermal energy can be sufficient to promote some electrons across the band gap and into the conduction band. These promoted electrons become mobile, contributing to the material's conductivity.

This behavior is significant in semiconductor devices, where the ability to control the flow of electrons is essential. By carefully selecting materials with small band gaps, semiconductor devices can exhibit desired electrical characteristics, such as enhanced conductivity, the ability to amplify signals, and the generation of light in light-emitting diodes (LEDs).

In summary, materials with small band gaps allow electrons to be easily promoted to the conduction band at ordinary temperatures, leading to their electrical conductivity and enabling various applications in semiconductor technology.
