Both the options are correct that principal energy level is represented by a positive integer and that it determines the orbital size.

The energy of an electron in an atom is determined by the primary energy level, which is symbolised by a positive integer. For instance, there is just one subshell, known as the s subshell, in the first energy level, and it can only accommodate up to two electrons.

As a result, the single electron present in an atom with a single primary energy level would be located in the 1s orbital. Hence, the orbital size increases with the principal energy level, which causes the electrons to be further from the nucleus and to have more energy.

If the pH of the solution is adjusted to 3.86 by the addition of concentrated NaOH, the lactate and lactic acid will be at equilibrium.

At this pH, lactate will be predominantly in its ionized form (lactate ion), while lactic acid will be predominantly in its unionized form. The concentration of lactate and lactic acid can be calculated using the Henderson-Hasselbalch equation: pH = pKa + log([lactate]/[lactic acid]).

Rearranging the equation: [lactate]/[lactic acid] = 10^(pH - pKa), At pH 3.86, the pKa of lactic acid is 3.86, so [lactate]/[lactic acid] = 10^(3.86 - 3.86) = 1
This means that the concentration of lactate and lactic acid will be equal at equilibrium. The actual concentration will depend on the initial concentration of the solution and the amount of concentrated NaOH added to adjust the pH.

Total, 56.2 grams of NaCl will be produced from 33.0 g of Na and 34.0 g of Cl₂.

To determine the amount of NaCl produced from 33.0 g of Na and 34.0 g of Cl₂, we need to first convert the given masses of Na and Cl₂ to moles using their respective molar masses;

Molar mass of Na = 23.0 g/mol

Molar mass of Cl₂ = 2 x 35.5 g/mol = 71.0 g/mol

Number of moles of Na = 33.0 g / 23.0 g/mol = 1.43 mol

Number of moles of Cl₂ = 34.0 g / 71.0 g/mol = 0.48 mol

Balanced chemical equation shows that 2 moles of Na will reacts with 1 mole of Cl₂ to produce a 2 moles of NaCl. Therefore, the limiting reactant in this reaction is Cl₂ since it is the reactant that produces the least amount of product.

From balanced equation, we can see that 1 mole of Cl₂ produces 2 moles of NaCl. So, the number of moles of NaCl produced from 0.48 moles of Cl₂ is;

0.48 mol Cl₂ x (2 mol NaCl / 1 mol Cl₂) = 0.96 mol NaCl

Finally, we can convert the number of moles of NaCl produced to grams using its molar mass;

Molar mass of NaCl = 23.0 g/mol + 35.5 g/mol = 58.5 g/mol

Mass of NaCl produced = 0.96 mol x 58.5 g/mol = 56.2 g

The molecular formula has two empirical units: C2H4Br x 2 = C4H8Br2. Therefore, the correct answer is A) C4H8Br2.

To find the molecular formula, we need to first determine the molecular mass of the compound. We know the empirical formula is C2H4Br, which has a total mass of 12.01x2 + 1.01x4 + 79.90 = 93.94 g/mol.

We are given the molar mass of the compound as 215.90 g/mol, which is more than twice the mass of the empirical formula. This indicates that there are multiple empirical units in the molecular formula.

To determine the number of empirical units, we divide the molar mass by the empirical mass:

215.90 g/mol / 93.94 g/mol = 2.3

This means that there are 2.3 empirical units in the molecular formula. However, we cannot have a fractional number of empirical units, so we need to multiply the empirical formula by a whole number to get the molecular formula.

We can do this by dividing 2.3 by the smallest number which will give us a whole number. In this case, that number is 1.15:

2.3 / 1.15 = 2

So the molecular formula has two empirical units:

C2H4Br x 2 = C4H8Br2

A symmetrical airfoil at a zero AOA develops positive lift.

A symmetrical airfoil has the same curvature on both its upper and lower surfaces, which means that the air flowing over the top and bottom of the airfoil has equal distances to travel, and therefore, produces no net lift when the angle of attack is zero. However, when the angle of attack is increased, the air flowing over the upper surface has to travel a longer distance than the air flowing over the lower surface, which results in lower pressure and higher velocity over the top of the airfoil, creating positive lift.

A non-rotating cylinder, on the other hand, does not develop positive lift.

In an aldol condensation reaction, a dehydration step is required to form the α,β-unsaturated carbonyl compound. During this step, a water molecule is removed from the molecule.

Water is a good leaving group because it is a stable, neutral molecule with a polar covalent bond, which makes it easy to break. The oxygen atom in the hydroxyl group of the reactant molecule is highly electronegative and pulls the bonding electrons toward itself, making the bond between the oxygen and hydrogen atoms polar.

As a result, the hydrogen atom becomes partially positive and is attracted to the negatively charged oxygen atom in another molecule, which leads to the formation of a water molecule. This leaving group ability of water makes it a suitable molecule for the dehydration step in aldol condensation reactions.

Answer:

When a force is applied to an object, the object may experience a change in its shape, depending on the strength and direction of the force, as well as the physical properties of the object.

If the force applied is too weak, the object may not change its shape at all. However, if the force is strong enough, the object may deform or bend. The amount of deformation or bending will depend on the amount of force applied and the object's elasticity or stiffness.

If the force is applied in a particular direction, the object may change its shape in that direction. For example, if a force is applied to the side of a rectangular object, it may cause the object to bend or deform in that direction.

In some cases, if the force applied is too strong, the object may break or fracture. This can happen if the force is applied to a weak point or if the object is not strong enough to withstand the force.

The wavelength of light with a frequency of 4.36 x 10^15 Hz is approximately 68.9 nanometers.

To calculate the wavelength of light in nanometers, we can use the formula:

wavelength = speed of light/frequency

The speed of light is approximately 3.00 x 10^8 meters per second. We need to convert the frequency of 4.36 x 10^15 Hz to Hz. Thus,

wavelength = (3.00 x 10^8 m/s) / (4.36 x 10^15 Hz)

Simplifying this expression, we get:

wavelength = 0.0689 x 10^-6 m = 68.9 x 10^-9 m
