I require only one electron to complete its outer shell. Therefore option 2 is correct.

The elements in the halogen family, including fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At), are very reactive because they require only one electron to complete their outermost electron shell.

In terms of their electron configuration, halogens have seven valence electrons, which is one electron short of a full outer shell. This electron configuration makes them highly reactive as they have a strong tendency to gain an additional electron to achieve a stable electron configuration with a full outer shell of eight electrons.

This is known as achieving a noble gas configuration, similar to the noble gases in Group 18.

In summary, the high reactivity of halogens is primarily due to their strong desire to gain one electron to complete their outermost electron shell and achieve greater stability.

In solution 4 of part b, both the hydronium concentration and hydroxide concentration are 1 M due to the neutralization reaction between HCl and NaOH. The initial concentrations of H₃O⁺ and OH⁻ were 0.1 M, but they reacted to form water and resulted in equal final concentrations of 1 M for both ions.

To calculate the hydronium and hydroxide concentrations for solution 4 in part b, we need to first understand the equation for the reaction that occurred.

The equation given is: HCl + NaOH -> NaCl + H₂O

This tells us that one mole of HCl reacts with one mole of NaOH to produce one mole of NaCl and one mole of water.

Based on this equation, we know that the initial concentration of hydroxide ions (OH-) in solution 4 is equal to the initial concentration of sodium hydroxide (NaOH), which was given as 0.1 M.

Next, we need to determine the concentration of hydronium ions (H₃O⁺). Since HCl is a strong acid, it completely dissociates in water to produce H₃O⁺ and Cl⁻ ions. Therefore, we can assume that the initial concentration of H₃O⁺ is equal to the initial concentration of HCl, which was also given as 0.1 M.

Now, let's consider what happens when the HCl and NaOH are mixed together. They react to form NaCl and water, which means that the concentrations of H₃O⁺ and OH⁻ will change.

From the equation, we can see that the reaction consumes one mole of HCl and one mole of NaOH. This means that the final concentration of HCl and NaOH will both be zero.

To determine the final concentration of OH-, we need to use the fact that the reaction produces one mole of water for every mole of NaOH that reacts. Therefore, the final concentration of OH⁻ will be equal to the initial concentration of NaOH (0.1 M) divided by the volume of the solution.

If we assume that the volume of the solution is 100 mL (as stated in the question), then the final concentration of OH- will be:

[OH⁻] = 0.1 M / 0.1 L = 1 M

Finally, we can use the fact that the concentration of H₃O⁺ and OH⁻ must be equal in a neutral solution to determine the final concentration of H₃O⁺.

Since the final concentration of OH⁻ is 1 M, we know that the final concentration of H₃O⁺ must also be 1 M.

The vapor pressure of water at 81°C is 3.61 atm.

To calculate the vapor pressure of water at 81°C, we can use the Clausius-Clapeyron equation, which relates the vapor pressure of a substance to its enthalpy of vaporization and temperature.

The equation is:

ln(P2/P1) = (ΔHvap/R) x (1/T1 - 1/T2)

where:P1 = vapor pressure at temperature T1

P2 = vapor pressure at temperature T2

ΔHvap = heat of vaporization

R = gas constant (8.314 J/mol K)

We can use the equation to solve for P2, given that we know P1, ΔHvap, T1, and T2. We will assume that the heat of vaporization of water is constant over this temperature range.

First, we need to convert the temperatures to Kelvin:

T1 = 25°C + 273.15 = 298.15 K

T2 = 81°C + 273.15 = 354.15 K

Next, we can plug in the values we know:

ln(P2/3.13x10-²) = (4.39x10⁴ J/mol / 8.314 J/mol K) x (1/298.15 K - 1/354.15 K)

Simplifying the right-hand side of the equation:

ln(P2/3.13x10-² atm) = 19.7

Finally, solving for P2:

P2/3.13x10-² atm = e¹⁹·⁷

To find the temperature of neon, we can use the ideal gas law equation which states that PV = nRT, where P is the absolute pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the temperature in Kelvin. Since both gases have the same mass density and the same absolute pressure, we can assume that they also have the same volume and number of moles.

We know that the mass density of helium is less than that of neon, which means that the same volume of helium contains fewer moles than neon. However, since the volume is the same, the number of moles must be equal for both gases. Therefore, we can use the mass density to find the number of moles of helium: mass density = mass/volume mass = mass density x volume n = mass/molar mass n(He) = (mass density of He x volume)/(molar mass of He) Similarly, we can find the number of moles of neon: n(Ne) = (mass density of Ne x volume)/(molar mass of Ne) Since both gases have the same number of moles and absolute pressure, we can equate their ideal gas law equations: PV = n(He)RT(He) = n(Ne)RT(Ne) Substituting the values, we get: P x V = [(mass density of He x volume)/(molar mass of He)] x R x 175 P x V = [(mass density of Ne x volume)/(molar mass of Ne)] x R x T(Ne) Dividing both equations, we get: T(Ne) = [(mass density of He x molar mass of Ne)/(mass density of Ne x molar mass of He)] x 175 Substituting the values, we get: T(Ne) = [(0.1785 kg/m^3 x 20.18 g/mol)/(0.9002 kg/m^3 x 4.003 g/mol)] x 175 T(Ne) = 70.5 K Therefore, the temperature of neon is 70.5 K.

When the volume of a system involving gaseous substances is decreased, the pressure within the system increases.

This is due to the fact that the molecules of the gas are being forced into a smaller space, causing them to collide more frequently with each other and the walls of the container. As a result, the concentration of the reactants in the system increases, leading to a shift in the equilibrium position.

According to Le Chatelier's Principle, when a system at equilibrium is subjected to a stress (such as a change in pressure, temperature, or concentration), it will respond by shifting in a direction that counteracts the stress. In the case of a decrease in volume, the system will respond by shifting in the direction that produces fewer moles of gas.

For example, consider the equilibrium reaction between nitrogen dioxide and dinitrogen tetroxide:

2NO₂(g) ⇌ N₂O₄(g)

If the volume of the system is decreased by compressing the container, the pressure within the container will increase, causing the equilibrium to shift to the right in order to reduce the number of gas molecules. This will result in an increase in the concentration of N₂O₄ and a decrease in the concentration of NO₂.

Overall, the effect of decreasing the volume of a system involving gaseous substances is to increase the pressure within the system and shift the equilibrium position in a direction that produces fewer moles of gas.

The molecular geometry of a molecule is determined by the arrangement of its atoms in three-dimensional space. In the case of NH3 and H2CO, both molecules have three electron groups around the central atom. However, the molecular geometries of these molecules are not the same due to differences in the electronegativity and hybridization of their central atoms.

In NH3, the central nitrogen atom has three electron groups and is sp3 hybridized. The four sp3 hybrid orbitals are arranged in a tetrahedral geometry around the nitrogen atom, with the three hydrogen atoms occupying three of the four orbitals. The lone pair of electrons on the nitrogen atom occupies the fourth orbital, giving the molecule a trigonal pyramidal molecular geometry.

In contrast, the central carbon atom in H2CO also has three electron groups, but is sp2 hybridized. The three sp2 hybrid orbitals are arranged in a trigonal planar geometry around the carbon atom, with the two hydrogen atoms occupying two of the three orbitals. The remaining sp2 hybrid orbital forms a double bond with the oxygen atom, giving the molecule a bent or V-shaped molecular geometry.

Therefore, the difference in the molecular geometry of NH3 and H2CO can be attributed to differences in the hybridization and electronegativity of their central atoms.
