Answer:

The shape of a molecule based on the number of electron pairs on the valence shell of its central atom

Explanation:

The improvement of the Sidgwick-Powell theory came to be known as the Valence Shell Electron Pair Repulsion theory (VSEPR). This theory approaches the determination of molecular shape from the perspective of the number of electron pairs on the valence shell of the central atom in the molecule.

Electron pairs on the valence shells of atoms leads to repulsion. Repulsion between two lone pairs is greater than repulsion between a lone pair and a bond pair which is also greater than repulsion between two bond pairs.

Lone pairs cause more repulsion, hence they distort molecules from the ideal shape predicted based on their electron domain geometry.

In the given reaction, 6 moles of sodium react with aluminum oxide to produce 2 moles of aluminum and 3 moles of sodium oxide. When 5.52 g of sodium is reacted with excess aluminum oxide, 1.00 g of aluminum is produced.

To calculate the theoretical yield of aluminum, we need to determine the molar mass of sodium (Na) and aluminum (Al). With the molar masses, we can convert the given mass of sodium (5.52 g) to moles. Since the reaction has a 6:2 ratio between sodium and aluminum, we can use stoichiometry to calculate the moles of aluminum produced.

Next, we can convert the moles of aluminum to grams using the molar mass of aluminum. This gives us the theoretical yield of aluminum.

To calculate the percent yield, we divide the actual yield (1.00 g) by the theoretical yield and multiply by 100%.

Percent Yield = (Actual Yield / Theoretical Yield) * 100%

Substituting the values, we can calculate the percent yield.

The advantage of making a solvent unblocking lightly nonpolar is to increase the solubility of polar and ionic compounds.

The solubility of a solute in a solvent is largely determined by the relative polarity of the solute and solvent. Polar solvents dissolve polar solutes, while nonpolar solvents dissolve nonpolar solutes. Making a solvent unblock lightly nonpolar increases its ability to dissolve polar and ionic compounds by reducing the difference in polarity between the solvent and solute.

This allows polar and ionic compounds to be dissolved in a nonpolar solvent, which can be useful in various applications, such as chromatography and chemical reactions.

The equilibrium concentration of H₃O⁺ in a 0.20 M solution of oxalic acid is 0.096 M. The units are M or mol/L.

Oxalic acid is a weak acid, so it undergoes a partial dissociation in water:

H₂C₂O₄ (aq) ⇌ H+ (aq) + HC₂O₄- (aq)

The equilibrium constant expression for this reaction is:

Ka = [H⁺][HC₂O₄⁻]/[H₂C₂O₄]

We can use the given concentration of oxalic acid (0.20 M) and the equilibrium constant (Ka = 5.9 x 10²) to solve for the concentration of H⁺ at equilibrium:

Ka = [H⁺][HC₂O₄⁻]/[H₂C₂O₄]

5.9 x 10⁻² = x²/0.20

x² = 0.20 x 5.9 x 10⁻²

x = 0.096 M

As a result, 0.096 M of H₃O⁺ is the equilibrium concentration in a 0.20 M solution of oxalic acid (to two significant figures). M or mol/L are the units.

3906.114 grams of CaCO₃ is required to completely react with 1250 grams of SO₂.

Scrubbing mechanism is a method of removing pollutants, such as sulfur dioxide (SO₂), from industrial exhaust gases. In this mechanism, a substance, such as limestone or lime, is added to the exhaust gases, which react with the pollutants to form solid waste products that can be easily removed.

The balanced chemical equation for the reaction of SO₂ gas and CaCO₃ is:

SO₂ + CaCO₃ → CaSO₃ + CO₂

From the equation, we can see that one mole of SO₂ reacts with one mole of CaCO₃. Therefore, we need to first determine the number of moles of SO₂ in 1250 g of SO₂:

molar mass of SO₂ = 32.066 g/mol

moles of SO₂ = mass of SO₂ / molar mass of SO₂

moles of SO₂ = 1250 g / 32.066 g/mol

moles of SO₂ = 39.012 mol

Since one mole of SO₂ reacts with one mole of CaCO₃, we need 39.012 moles of CaCO₃ to react with the 39.012 moles of SO₂. The molar mass of CaCO₃ is 100.086 g/mol, so we can calculate the mass of CaCO₃ needed as:

mass of CaCO₃ = moles of CaCO3₃ × molar mass of CaCO₃

mass of CaCO₃ = 39.012 mol × 100.086 g/mol

mass of CaCO₃ = 3906.114 g

Therefore, we need 3906.114 grams of CaCO₃ to completely react with 1250 grams of SO₂.

There are many scenarios in which the situation in question may take place, the rule is that for this to happen, the temperature and pressure of the gas must change by the same amount.

As stated, the temperature and the pressure of the enclosed gas may change, in which they may increase or decrease, but the change must be by the same magnitude for each value. What this means is that is temperature increases by 5, so then must the pressure.

This is due to the relationship between the temperature and the pressure of an enclosed gas when using the combined gas law. The law takes the form of a fraction in which the pressure is found as part of the numerator and the temperature is part of the denominator, therefore, by increasing at the same rate, the final product and the volume will not be affected.

The work done by the gas is -8.00 L.atm.

Given data:

Initial volume = 8.00 L

Final volume = 16.0 L

External pressure = 1.00 atm

The equation for the work done by a gas during a reversible, isothermal process is given by: W = - nRT \ln \frac{V_f}{V_i}

where n is the number of moles of the gas, R is the gas constant (8.31 J/(mol.K) for ideal gases), T is the temperature in Kelvin, V_i and V_f are the initial and final volumes of the gas respectively.

Since the pressure of the gas is constant, the process is isobaric (constant pressure).

Therefore, W = - P \Delta V$$where P is the external pressure and $\Delta V = V_f - V_i is the change in volume. ,

Substituting the given values into the above equation, we haveW = - (1.00 \; \text{atm}) \times (16.0 \; \text{L} - 8.00 \; \text{L})W = -8.00 \; \text{L.atm}
