A volume of 35 ml of nitrogen gas was collected over water at 4 and 99.1 kpa. the vapor pressure of water at this temperature is 2.99 kpa, the pressure of nitrogen is 96.11 kpa.

According the Dalton's law of partial pressure :

P total = P H₂O  +  PN₂

P total = 99.1 kpa

P H₂O = 2.99 kpa

PN₂ = P total - P H₂O

PN₂ = 99.1 kpa - 2.99 kpa

PN₂ = 96.11 kpa

Thus, A volume of 35 ml of nitrogen gas was collected over water at 4 and 99.1 kpa. the vapor pressure of water at this temperature is 2.99 kpa, the pressure of nitrogen is 96.11 kpa.

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%

                                       = 0.7518

Hence the percent yield is 0.7518.

From the balanced equation above,

1 mole of H₂ was obtained from 1 mole of Zn

Therefore,

0.15 mole of H₂ will also be obtained from 0.15 mole of Zn.

Finally, we can obtain the mass of zinc, Zn required as follow:

Mole = mass / molar mass

1.15 = Mass of zinc, Zn / 65.38

Cross multiply

Mass of zinc, Zn = 0.15 × 65.38

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)

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.

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:

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.

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.

Constant b is dependent on the volume or indirectly radius of the compound. Sulfur dioxide is composed of more than one atom and hence its net volum3e must be higher than that of Ne . Thus sulfur dioxide must have a higher b value.
