Samarium:

Electron configuration:

Samarium

Explanation:

Samarium is a chemical element that belongs to the lanthanoid series. The lanthanoids are the chemical elements that follow lanthanum. They are all known to possess 4f orbitals. The 4f electrons are found in the antepenultimate shell of the elements of the lanthanoid series and they do not take part in chemical bonding. They are neither removed in bonding nor do they take part in crystal field stabilization of lanthanoid complexes.

The electronic configuration of samarium is; 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f6 while the condensed, short hand electronic configuration is [Xe] 4f6 6s2. This corresponds to (noble gas]ns2(n − 2) f6 as required by the question, hence the answer provided above.

Answer:

The correct answer is - 5L.

Explanation:

From the ideal gas equation -

pv=nRT

p = pressure

v =volume

Here nRT is constant so

P would be inversely proportioned to v

So, p1/p2 = v2/v1

Putting values:

2/4(2) = v2/20 (p2 = 4 times of P1)

2/8 = v2/20

V2 = 5

Thus, the correct volume at new pressure would be - 5 L.

The mass proportion of sugar in the initial combination, assuming complete dissociation of the salt, is 55.0%.

There are 58.44 g/mol of NaCl in the mixture, which equals the following:

Moles of NaCl are equal to the mass of NaCl divided by the molar mass of NaCl. For example, 10.40 g - x g = 58.44 g/mol

NaCl dissolves into two particles, hence there are actually two particles in the solution.

effective particles equal 2 moles of sodium chloride plus 1 mole of sugar.

2.24 °C = 1.86 °C mol/kg x (27.63 - 0.605 x) mol/kg

Explanation:

The following data were obtained from the question:

Mass of KOH = 42.3 g

Molar mass of KOH = 56.11 g/mol

Mass of water = 329 g

Molality of KOH = ?

Next, we shall determine the number of mole in 42.3 g of KOH. This can be obtained as follow:

Mass of KOH = 42.3 g

Molar mass of KOH = 56.11 g/mol

Mole of KOH =?

Mole = mass /Molar mass

Mole of KOH = 42.3/56.11

Mole of KOH = 0.754 mole

Next, we shall convert 329 g of water to kilogram (kg). This can be obtained as follow:

1000 g = 1 kg

Therefore,

329 g = 329 g /1000 g × 1 kg

329 g = 0.329 kg

Therefore, 329 g of water is equivalent to 0.329 kg

Finally, we shall determine the molality of the KOH solution ad follow:

Molality is defined as the mole of solute per unit kilogram of solvent (water) i.e

Molality = mole/ mass (kg) of water

Mole of KOH = 0.754 mole.

Mass of water = 0.329 kg.

Molality = mole/ mass (kg) of water

Molality = 0.754/0.329

Molality = 2.29 m

Therefore, the molality of the KOH solution is 2.29 m.

\(\boxed {\boxed {\sf 0.80 \ mol\ F}}\)

Explanation:

We are asked to find how many moles are in 4.8 × 10²³ fluorine atoms. We convert atoms to moles using Avogadro's Number or 6.022 × 10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance. In this case, the particles are atoms of fluorine.

We will convert using dimensional analysis and set up a ratio using Avogadro's Number.

\(\frac {6.022 \times 10^{23} \ atoms \ F}{ 1 \ mol \ F}\)

We are converting 4.8 × 10²³ fluorine atoms to moles, so we multiply the ratio by this number.

\(4.8 \times 10^{23} \ atoms \ F *\frac {6.022 \times 10^{23} \ atoms \ F}{ 1 \ mol \ F}\)

Flip the ratio so the units of atoms of fluorine cancel each other out.

\(4.8 \times 10^{23} \ atoms \ F *\frac { 1 \ mol \ F}{6.022 \times 10^{23} \ atoms \ F}\)

\(4.8 \times 10^{23} *\frac { 1 \ mol \ F}{6.022 \times 10^{23} }\)

Condense into 1 fraction.

\(\frac { 4.8 \times 10^{23} }{6.022 \times 10^{23} } \ mol \ F\)

Divide.

\(0.7970773829 \ mol \ F\)

The original measurement of atoms has 2 significant figures, so our answer must have the same. For the number we found, that is the hundredths place. The 7 in the thousandths tells us to round the 9 in the hundredths place up to a 0. Then, we also have to round the 7 in the tenths place up to an 8.

\(0.80 \ mol \ F\)

4.8 × 10²³ fluorine atoms are equal to 0.80 moles of fluorine.

The moon cycle goes from right to left

The total gaseous mixture is 4.48 g.

The total gaseous mixture can be calculated using the ideal gas law: PV = nRT.

First, we need to convert the temperature to Kelvin: 27.0°C + 273.15 = 300.15 K.

Next, we can use the ideal gas law to calculate the number of moles of each gas:

For He: n = (1.12 atm) (2.00 L) / (0.08206 L·atm/mol·K) (300.15 K) = 0.0906 mol

For Ar: n = (4.53 g) / (39.95 g/mol) = 0.113 mol

The total number of moles of gas in the mixture is then:

n(total) = n(He) + n(Ar) = 0.0906 mol + 0.113 mol = 0.204 mol

Finally, we can calculate the total mass of the mixture:

m(total) = n(total) × M(avg)

where M(avg) is the average molar mass of the mixture, which can be calculated as:

M(avg) = (M(He) + M(Ar)) / 2 = (4.003 g/mol + 39.95 g/mol) / 2 = 21.98 g/mol

Thus,

m(total) = 0.204 mol × 21.98 g/mol = 4.48 g

Therefore, The total weight of the gaseous mixture is 4.48 g.

Approximately 4.37 x 10^23 molecules of HCl would be required to form 34.52 g of MgCl₂.

To determine the number of molecules of HCl required to form 34.52 g of MgCl₂, we need to use the molar mass and stoichiometry of the balanced equation:

Mg(OH)₂(s) + 2 HCl(aq) → 2 H₂O(l) + MgCl₂(aq)

The molar mass of MgCl₂ is 95.21 g/mol.

First, we need to calculate the number of moles of MgCl₂ formed:

Moles of MgCl₂ = mass of MgCl₂ / molar mass of MgCl₂

Moles of MgCl₂ = 34.52 g / 95.21 g/mol

Moles of MgCl₂ = 0.363 mol

According to the balanced equation, the stoichiometric ratio between HCl and MgCl₂ is 2:1. Therefore, the moles of HCl required can be calculated as follows:

Moles of HCl = 2 * Moles of MgCl₂

Moles of HCl = 2 * 0.363 mol

Moles of HCl = 0.726 mol

To calculate the number of molecules, we need to use Avogadro's number, which is approximately 6.022 x 10^23 molecules/mol.

Number of molecules of HCl = Moles of HCl * Avogadro's number

Number of molecules of HCl = 0.726 mol * 6.022 x 10^23 molecules/mol

Number of molecules of HCl = 4.37 x 10^23 molecules

Therefore, approximately 4.37 x 10^23 molecules of HCl would be required to form 34.52 g of MgCl₂.
