B2 has a bond order of 1.
Bond order is the number of electron bonding pairs that exist between two atoms. An unmarried bond has a bond order of one in a covalent bond between atoms, a double bond has a bond order of two, a triple bond has a bond order of three, and so on.
Calculation:-
for b2 = 1s2 1s*2 2s2 1s*2 2Px1 = 2Py1
(Nb - Na)/2 bond order
= 6 - 4 /2
= 1.
Bond order, as described by Linus Pauling, is defined by the difference in the number of bonds and anti-bonds. The number of electron pairs between two atoms determines the bond order. In diatomic nitrogen NN, for example, the bond order between the two nitrogen atoms is three.

Which information is sufficient to differentiate a sample of sodium from a sample of silver?.
The reactivity of each sample with water is sufficient to differentiate a sample of sodium from a sample of silver.
Silver is a highly reactive metal and will react with water to form silver hydroxide and hydrogen gas. The reaction of silver with water can be represented as follows:
2Ag (s) + 2H₂O (l) → 2AgOH (aq) + H₂ (g)
Sodium is also a highly reactive metal and will react with water to form sodium hydroxide and hydrogen gas. The reaction of sodium with water can be represented as follows:
2Na (s) + 2H₂O (l) → 2NaOH (aq) + H₂ (g)
Both of these reactions are highly exothermic, meaning they release a large amount of energy. This energy can be dangerous if not handled properly. The reaction between sodium and water is particularly dangerous because it releases a large amount of heat and can cause the water to boil violently. This can result in the water splashing and burning the skin. For this reason, it is important to handle these reactions with caution.

How can a dilation be made from a pre image?.
A dilatation is a type of transformation that enlarges or reduces a figure (known as the preimage) to create a new figure (called the image)
Explain about the dilatation?Triglyceride dilation is the thermal expansion of crystalline triglycerides. When length scales (or energy scales) are multiplied by a common factor, an object's or law's scale invariance property does not change. A transformation called a dilation (similarity transformation) alters the size of a figure. A center point and a scaling factor, k, are necessary. Which kind of dilation it is—an enlargement or a reduction—depends on the value of k. An enlargement results from a dilatation if |k|>1. The reduction is the dilation if |k| 1.
To determine a dilated figure's scale factor, use the following simple formula: Scale factor is the product of the old shape's dimension and the new shape's dimension.

Calculate the theoretical yield of C2H5Cl if 112 g of C2H5OH is reacted with 58.3 g of PCl3. If only 61.8 g of C2H5Cl are produced, what is the percent yield?
The theoretical yield of C₂H₅Cl if 112 g of C₂H₅OH is reacted with 58.3 g of PCl₃ is 82.2 g and percent yield is 0.7518.
The balanced chemical equation for the reaction of C₂H₅Cl and PCl₃ is given as:
3 C₂H₅OH + PCl₃ → 3 C₂H₅Cl + H₃PO₃
1 mole of C₂H₅OH = 46 g
1 mole of PCl₃ = 137.33 g
1 mole of C₂H₅Cl = 64.51 g
3 moles of ethanol react with 1 mole of PCl₃
112 g of ethanol react with PCl₃ = (137.33 × 112) / (3 × 46)
= 111.45 g of PCl₃
Given amount of PCl₃ = 58.3 g
Hence, PCl₃ is the limiting reagent.
1 mole of PCl₃ produces 3 moles of C₂H₅Cl.
58.3 g of PCl₃ produces C₂H₅Cl = (3 × 64.51 × 58.3) / (137.33)
= 11282.7 / 137.33
= 82.2 g
Hence, the theoretical yield of C₂H₅Cl is 82.2 g.
For C₂H₅Cl,
Actual yield = 61.8 g
Theoretical yield = 82.2 g
∵ Percent yield = (Actual yield / Theoretical yield) × 100%
Substituting the values,
Percent yield of C₂H₅Cl = (61.8 / 82.2) × 100%
= 0.7518 × 100%

Hence the percent yield is 0.7518.

The correct statement here is both the Vander walls constant a and b have a higher value for sulfur dioxide
Real gases are gases that do not follow the ideal gas equation. Instead it shows deviations in pressure and volume of the gas that usually arises due to the interaction between atoms and the size of the atoms being of the significant value. These deviations are generally dealt with by introduction of two constants(a and b) which are called as the van der Waals constant.
The Van der Waal constant 'a' signifies the magnitude of the attraction between the gas molecules, and the constant 'b' signifies the effective volume occupied by the gas molecules.
The van der Waals constants a and can be compared between two gases using the factors on which they depend.
Constant a depends on the interactions present in a gas. Sulfur dioxide is a compound that is showing interactions in the form of bonding while Ne is an element of the noble gas family which is in a stable octet state and shows no interactions. Thus sulfur dioxide must have higher a value.
