Answer:

Average atomic mass of X= 64.25 amu

Explanation:

Abundance of X-64 = 80%

Abundance of X-65 = 15%

Abundance of X-66 = 5%

Average atomic mass = ?

Solution:  

Average atomic mass of X = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  + (abundance of 3rd isotope × its atomic mass)  / 100

Average atomic mass of X= (80×64)+(15×65) +(5×66) /100

Explanation:

The following data were obtained from the question:

Mass of Iron = 28.5 g

Volume of water = 45.5 mL

Volume of water + Iron = 49.1 mL.

Density of Iron =.?

Next, we shall determine the volume of the iron. This can be obtained as illustrated below:

Volume of water = 45.5 mL

Volume of water + Iron = 49.1 mL.

Volume of iron =.?

Volume of iron = (Volume of water + Iron) – (volume of water)

Volume of iron = 49.1 – 45.5

Volume of iron = 3.6 mL

Finally, we shall determine the density of iron as follow:

Mass of Iron = 28.5 g

Volume of iron = 3.6 mL

Density of Iron =.?

Density = mass/volume

Density = 28.5/3.6

Density = 7.92 g/mL

Therefore, the density of the iron is 7.92 g/mL

Using the expression of Clausius-Clapeyron equation we can calculate the vapor pressure. Putting all the values in the expression we get the result.

The vapor pressure can be defined as the force that an evaporating substance exerts against the walls of a sealed container. ln (P1/P2) = (ΔHvap. /R) (1/T2 - 1/T1). where, P1 and  P2 are the vapor pressures at two temperatures T and T2 . A solution made from 23.5 g of glycerin in 130 g of methanol at 50 °C. The vapor pressure of pure methanol at 50 °C is 400 torr. Clausius-Clapeyron equation allows to estimate the vapor pressure at another temperature if the vapor pressure is known at some temperature and if the enthalpy of vaporization is known.

Answer:

5 moles of Sodium are required to produce 5 moles of Sodium Chloride.

Explanation:

I am assuming you were not given an equation and this is a synthesis reaction.

Let's begin by writing a balanced chemical equation for the synthesis of sodium chloride.

2Na⁺ + Cl₂⁻ -> 2NaCl

Since Cl₂ exists as a diatomic molecule, we must have 2 +1 charges from Na to balance out the 2 -1 charges of Cl₂ (-1 for each Cl atom). This will then form 2 moles of NaCl.

To produce 5 moles of sodium chloride, we can multiply the entire equation by 2.5. This will result in:

5Na⁺ + 2.5Cl₂⁻ -> 5NaCl

The stoichiometric ratios of this new equation is:

5 Na: 2.5 Cl₂: 5NaCl

5 moles of sodium (Na) are required to produce 5 moles of sodium chloride (NaCl).

Explanation:

The concentration of hydronium ions at 100°C is 7.16 x 10⁻⁷ mol/L.

The ion product of water at 100°C is 5.13 x 10⁻¹³.

We can use this information to calculate the concentration of hydronium ions at this temperature. The ion product of water, or Kw, is defined as the product of the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in water. This relationship is expressed as follows:

Kw = [H+][OH-, ]At 100°C, Kw = 5.13 x 10⁻¹³. Since pure water is neutral, the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-).

Therefore, we can write:[H+] = [OH-]

To solve for [H+], we need to take the square root of Kw:[H+] = √(Kw)[H+] = √(5.13 x 10^-13)[H+] = 7.16 x 10⁻⁷ mol/L

Therefore, the concentration of hydronium ions at 100°C is 7.16 x 10⁻⁷ mol/L.

The carburizing time necessary to achieve a carbon concentration of 0.30 wt% at a position 4 mm into an iron-carbon alloy is 63.4 hours.

To determine the carburizing time necessary to achieve a carbon concentration of 0.30 wt% at a position 4 mm into an iron-carbon alloy, we can use Fick's second law of diffusion:

\(DC_{surface} / 2 = (C_{surface} - C_{4mm}) / erf(x / (2 * \sqrt{Dt} ))\\\)

where D is the diffusion coefficient, \(C{surface}\\\) is the surface carbon concentration (0.90 wt%), C_4mm is the carbon concentration at the position 4 mm into the alloy (0.10 wt%), x is the distance from the surface (4 mm), and t is the carburizing time we want to find.

We can use the diffusion coefficient for γ-Fe at 1100°C from Table 5.2, which is D = \(6.0 * 10^{-12} m^2/s.\)

Substituting the given values, we get:

\((6.0 * 10^{-12} m^2/s) * (0.90 - 0.30) / 2 = (0.90 - 0.10) / erf(4 mm / (2 * \sqrt{6.0 * 10^{-12} m^2/s} ))\)

Simplifying the left-hand side, we get:

\(1.8 * 10^{-12} m^2/s = (0.80) / erf(4 mm / (2 * \sqrt{(6.0 * 10^{-12} m^2/s) * t)})))\)

Taking the inverse error function of both sides, we get:

\(erf(4 mm / (2 * \sqrt{6.0 * 10^{-12} m^2/s) * t)} ) = 0.000346\)

Substituting this back into the previous equation, we get:

\(1.8 * 10^{-12} m^2/s = (0.80) / 0.000346\)

Explanation:

To solve this problem, we need to use the balanced chemical equation for the reaction between hydrobromic acid (HBr) and magnesium hydroxide (Mg(OH)2):

2HBr + Mg(OH)2 -> MgBr2 + 2H2O

From the equation, we can see that 2 moles of hydrobromic acid react with 1 mole of magnesium hydroxide.

We are given the volume of the hydrobromic acid as 5.0 mL, but we do not know the number of moles of hydrobromic acid present. However, we do know the concentration and volume of the magnesium hydroxide used for the titration. We can use this information to calculate the number of moles of magnesium hydroxide used in the titration:

Molarity of Mg(OH)2 = 1.50 M

Volume of Mg(OH)2 used = unknown (we don't know how much was added to reach the endpoint)

We can assume that the reaction between the two solutions goes to completion and that all the magnesium hydroxide reacts with the hydrobromic acid present. Therefore, we can set up the following equation using the stoichiometry of the reaction:

2 moles HBr = 1 mole Mg(OH)2

moles of HBr = (moles of Mg(OH)2) / 2

Using the equation for molarity (M = moles / liters), we can calculate the number of moles of magnesium hydroxide used in the titration:

Molarity of Mg(OH)2 = moles of Mg(OH)2 / volume of Mg(OH)2

moles of Mg(OH)2 = Molarity of Mg(OH)2 x volume of Mg(OH)2

We don't know the volume of Mg(OH)2 used, but we can use the volume of hydrobromic acid and the balanced chemical equation to determine it. Since 2 moles of HBr react with 1 mole of Mg(OH)2, we can say that:

moles of Mg(OH)2 = (moles of HBr) / 2

Using the equation for molarity and the given volume of hydrobromic acid (5.0 mL or 0.005 L), we can calculate the number of moles of hydrobromic acid present:

Molarity of HBr = moles of HBr / volume of HBr

moles of HBr = Molarity of HBr x volume of HBr

Now we can combine the equations to solve for the unknown volume of magnesium hydroxide used in the titration:

moles of Mg(OH)2 = (Molarity of Mg(OH)2) x (volume of Mg(OH)2)

moles of HBr = 0.5 x moles of Mg(OH)2 (since 2 moles of HBr react with 1 mole of Mg(OH)2)

moles of HBr = (Molarity of HBr) x (volume of HBr)

Since the moles of HBr are the same in both equations, we can set them equal to each other:

(Molarity of HBr) x (volume of HBr) = 0.5 x (Molarity of Mg(OH)2) x (volume of Mg(OH)2)

Solving for the unknown variable, we get:

(Molarity of HBr) = (0.5 x (Molarity of Mg(OH)2) x (volume of Mg(OH)2)) / (volume of HBr)

(Molarity of HBr) = (0

Answer:It has the lowest effective nuclear charge of the four new elements.

The electronic configuration of the Organesson element is  [Rn]5f¹⁴6d¹⁰7s²7p⁶ so it has fully filled valence shell. As the last element in the periodic table, it has the largest atomic radius and the lowest effective nuclear charge. Therefore, option (C), (D), and (E) is correct.

The electron configuration gives information on how electrons are distributed in different energy levels of an atom of an element. In the electron configuration of an element, the number of electrons can be written as a superscript of electron-containing atomic subshells. For example, the electron configuration of magnesium is written as 1s²2s²2p⁶3s².

The principal quantum number (n) in electron configuration decides the maximum number of electrons that can fill in an electron shell. It is calculated from the formula 2n², where ‘n’ is the principal quantum number of the shell.

The atomic orbitals at lower energy must be fully filled before occupying an orbital at higher energy.

The atomic number of the Organesson element is 118 and the electronic configuration is [Rn]5f¹⁴6d¹⁰7s²7p⁶. Therefore, the valence shell of Organesson is fully filled. As the last element in the periodic table, it has the largest atomic radius and the lowest effective nuclear charge.

When 1.6 mol HCL and 2.5 mol NaOH react according to the equation ten 4 moles of H2O will form.

The reaction between 1.6 mol of HCl and 2.5 mol of NaOH is given by the following equation:

HCl + NaOH → NaCl + H2O

This equation tells us that for every mole of HCl that reacts with NaOH, one mole of H2O will be formed. Since we have 1.6 moles of HCl and 2.5 moles of NaOH, we can calculate the amount of H2O formed in the reaction by multiplying 1.6 and 2.5.

1.6×2.5=4
