Phosphorus reacts with chlorine gas to produce phosphorus trichloride:
1. Write the chemical equation and balance
2. How many moles of chlorine gas are required to produce 17 moles of PCI3 ?

Answers

Answer 1

Answer:

1. P4 + 6Cl2 → 4PCI3; already balanced

2. 25.5 moles Cl2

Explanation:

1. The chemical equation for the reaction of phosphorus with chlorine gas to produce phosphorus trichloride is:

P4 + 6Cl2 → 4PCI3

The equation is already balanced

2. The equation shows that 6 moles of chlorine gas are required to produce 4 moles of phosphorus trichloride.

set up a proportion:

6 moles Cl2 / 4 moles PCI3 = x moles Cl2 / 17 moles PCI3

solve for x:

x = (6 moles Cl2 / 4 moles PCI3) x 17 moles PCI3

x = 25.5 moles Cl2

Therefore, 25.5 moles of chlorine gas are required to produce 17 moles of phosphorus trichloride.

Answer 2

Answer:

25.5 moles of Cl₂ required

Explanation:

2P + 3Cl₂ --> 2PCl₃

Since, the stoichiometry (molar ratio) of the reaction is 2 : 3 : 2,

thus, number of moles of Cl₂ = 3/2 × number of moles of PCl₃

∴ number of moles of Cl₂ required is 25.5 moles

Derive an expression for lowering of vapour pressure and molar mass of solute






Answers

The expression for lowering of vapour pressure and molar mass of solute is given as -

                                                [tex]\frac{p^{0}- p }{p^{0} }[/tex] =  [tex]\frac{W_{2} }{M_{2} }[/tex] × [tex]\frac{M_{1} }{W_{1} }[/tex]

What is Raoult's law?

According to Raoult's law-

Relative lowering of vapour pressure of a non volatile solute is equal to the mole fraction of solute.

The relation between relative Lowering of vapour pressure and molar mass of solute is given as -

                                             [tex]\frac{p^{0}- p }{p^{0} }[/tex] = [tex]\frac{W_{2} }{M_{2} }[/tex] × [tex]\frac{M_{1} }{W_{1} }[/tex]

          where, [tex]p^{0}[/tex] = vapour pressure of pure solvent

                        p = vapour pressure of solution

                        [tex]W_{2}[/tex] = Mass of solvent

                       W₁ = mass of solute

                        M₂ = molar mass of solvent

                         M₁ = molar mass of solute.

                              Mole fraction of solute = [tex]\frac{n_{2} }{n_{1} + n_{2} }[/tex]

where, n₂ = number of moles of solvent

            n₁ = number of moles of solute

For dilute solution,  n₂ ∠∠n₁

Thus, n₂ can be neglected in the denominator and this gives,

                                                     [tex]\frac{p^{0}- p }{p^{0} }[/tex] = [tex]\frac{n_{2} }{n_{1} }[/tex]

We know that, number of moles = mass / molar mass.

Therefore replacing the values of  n₂ and n₁ with mass and molar mass gives-

                                                 [tex]\frac{p^{0}- p }{p^{0} }[/tex] = [tex]\frac{W_{2} }{M_{2} }[/tex] × [tex]\frac{M_{1} }{W_{1} }[/tex]

Therefore, this gives the relation between relative lowering of vapour pressure and molar mass of solute

According to the solubility graph of KNO₃, 0.160 moles  would have to be added to 100 g of water to form a saturated solution at 10°C.

What is solubility?

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.

At 40°C 67 g potassium nitrate is soluble thus at 10°C 10×67/40= 16.25 g is soluble which is 16.25/101.10= 0.160 moles.

What is the pressure (in atmospheres) exerted by a 0.500 mol sample of N2 gas in a 10.0 L container at 298 K?

Answers

To solve this problem, we can use the Ideal Gas Law, which relates the pressure (P), volume (V), number of moles (n), and temperature (T) of a gas. The Ideal Gas Law is expressed as:

PV = nRT

where R is the gas constant.

R = 0.0821 L·atm/mol·K

We can rearrange this equation to solve for pressure:

P = nRT/V

where:

n = 0.500 mol (number of moles of N2 gas)

R = 0.0821 L·atm/mol·K (gas constant)

T = 298 K (temperature)

V = 10.0 L (volume)

Substituting the values:

P = (0.500 mol)(0.0821 L·atm/mol·K)(298 K)/(10.0 L)

P = 12.1 atm

Therefore, the pressure exerted by a 0.500 mol sample of N2 gas in a 10.0 L container at 298 K is 12.1 atm.

P4Br7 is…
A. Phosphorus bromide
B. Phosphorus (IV) bromide
C. Phosphorus heptabromide
D. Tetraphosphorus heptabromide

Answers

The molecular formula P4Br7 represents a compound made of phosphorus and bromine atoms. To name this compound, we need to determine the oxidation state of the phosphorus atom and the number of bromine atoms present.

Since there are four phosphorus atoms, the prefix "tetra" is used. The Roman numeral in the name represents the oxidation state of phosphorus, which can be determined by dividing the total number of valence electrons of the phosphorus atoms by the number of phosphorus atoms present.

For P4Br7, the total number of valence electrons of the phosphorus atoms is 4 x 5 = 20, where 5 is the number of valence electrons of phosphorus. The total number of valence electrons contributed by the bromine atoms is 7 x 2 = 14, where 2 is the number of valence electrons of bromine. Thus, the total number of valence electrons in P4Br7 is 20 + 14 = 34.

To divide the total number of valence electrons by the number of phosphorus atoms, we get:

Oxidation state of P = Total valence electrons / Number of P atoms
= 34 / 4
= 8.5

Since the oxidation state of phosphorus is not a whole number, it suggests that the compound does not follow the typical rules for covalent bonding. Therefore, the compound P4Br7 is not a covalent compound but rather an ionic compound.

Out of the given options, none of them accurately represent the name of P4Br7. However, the closest option is D. Tetraphosphorus heptabromide, which represents a hypothetical compound that does not actually exist. Therefore, the correct answer is None of the above.
Final answer:

The correct name for P4Br7 is Tetraphosphorus heptabromide, which results from using prefixes to indicate the numbers of each type of atom present.

Explanation:

The correct name for the compound P4Br7 is D. Tetraphosphorus heptabromide. In chemical naming, the prefix 'tetra-' is used for four of an atom, in this case, phosphorus. Similarly, 'hepta-' is the prefix for seven, referring to the seven bromide atoms present. Therefore the name becomes Tetraphosphorus heptabromide.

4.6g of sucrose was added to 72.9g of water. What is the percent composition? Round to the tenths place.

Answers

Answer:

The percent composition by mass of a component in a mixture is given by:

percent composition = (mass of component / total mass of mixture) x 100%

In this case, the component is sucrose, and the total mass of the mixture is the sum of the mass of sucrose and the mass of water. We have:

mass of sucrose = 4.6 g mass of water = 72.9 g total mass of mixture = mass of sucrose + mass of water = 4.6 g + 72.9 g = 77.5 g

Substituting these values into the formula, we get:

percent composition of sucrose = (4.6 g / 77.5 g) x 100% = 5.94%

Rounding to the tenths place, we get:

percent composition of sucrose ≈ 5.9%

Therefore, the percent composition of sucrose in the mixture is approximately 5.9%.

If you put 10.0mL of a in one balance pan . How much mass of b would you need in the other pan to make it balanced

Answers

To balance 10.0 mL of substance a, we would need 6.67 g of substance b.

How did we arrive at the value?

To determine how much mass of substance b would be needed to balance 10.0mL of substance a on the other pan, we need to know the density of both substances.

If we know the density of substance a and the volume of substance b, we can calculate the mass of substance b needed to balance the system.

For example, if we assume that substance a has a density of 1.0 g/mL, and we want to balance it with substance b which has a density of 1.5 g/mL, we can use the following formula:

mass of substance b = (density of substance a) x (volume of substance a) / (density of substance b)

Substituting the values given, we get:

mass of substance b = (1.0 g/mL) x (10.0 mL) / (1.5 g/mL)

mass of substance b = 6.67 g

Therefore, to balance 10.0 mL of substance a, we would need 6.67 g of substance b.

How many moles of dinitrogen monoxide will be formed upon the complete reaction of 25.1 g of ammonium nitrate

Answers

Taking into account the reaction stoichiometry, 0.31375 moles of N₂O are formed upon the complete reaction of 25.1 g of ammonium nitrate.

Reaction stoichiometry

In first place, the balanced reaction is:

NH₄NO₃  → N₂O + 2 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amount of moles of each compound participate in the reaction:

NH₄NO₃: 1 moleN₂O: 1 moleH₂O: 2 moles

The molar mass of the compounds is:

NH₄NO₃: 80 g/moleN₂O: 44 g/moleH₂O: 18 g/mole

By reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

NH₄NO₃: 1 mole ×80 g/mole= 80 gramsN₂O: 1 mole ×44 g/mole= 44 gramsH₂O: 2 moles× 18 g/mole= 36 grams

Mass of N₂O formed

The following rule of three can be applied: if by reaction stoichiometry 80 grams of NH₄NO₃ form 1 mole of N₂O, 25.1 grams of NH₄NO₃ form how many moles of N₂O?

moles of N₂O= (25.1 grams of NH₄NO₃ ×1 mole of N₂O) ÷80 grams of NH₄NO₃

How many liters of NH, will be produced at a temperature of 208.00 degrees celsius and 4.50 torr pressure to consume 26.00 moles of N2?
Round to two decimal places.

Answers

Answer:

To solve this problem, we can use the ideal gas law and stoichiometry.

First, we need to convert the given temperature to Kelvin:

208.00 degrees Celsius + 273.15 = 481.15 K

Next, we can use the ideal gas law to find the volume of NH3 produced:

PV = nRT

P = 4.50 torr = 0.00592 atm (converting to atm)

V = unknown (what we are trying to find)

n = moles of NH3 produced = 26.00 moles N2 (from stoichiometry)

R = 0.0821 L·atm/K·mol (gas constant)

T = 481.15 K

Solving for V:

V = nRT/P

V = (26.00 mol)(0.0821 L·atm/K·mol)(481.15 K) / (0.00592 atm)

V = 3671.46 L

However, this is the volume of NH3 produced at standard temperature and pressure (STP), which is 0 degrees Celsius (273.15 K) and 1 atm. We need to convert this to the volume at the given temperature and pressure using the combined gas law:

(P1V1/T1) = (P2V2/T2)

P1 = 1 atm (STP pressure)

V1 = 3671.46 L (volume at STP)

T1 = 273.15 K (STP temperature)

P2 = 0.00592 atm (given pressure)

V2 = unknown (what we are trying to find)

T2 = 481.15 K (given temperature)

Solving for V2:

V2 = (P1V1T2) / (P2T1)

V2 = (1 atm)(3671.46 L)(481.15 K) / (0.00592 atm)(273.15 K)

V2 = 315491.48 L or 315491 L (rounded to two decimal places)

Therefore, 315491 L of NH3 will be produced at a temperature of 208.00 degrees Celsius and 4.50 torr pressure to consume 26.00 moles of N2.

The volume of an object can be calculated by multiplying its length, width, and height or by using other formulas specific to the shape of the object.

To calculate the volume of a solution, we need to use the formula:

volume (in liters) = amount of solute (in moles) / concentration (in moles per liter)

In this case, we have:

Amount of solute = 0.55 moles

Concentration = 0.46 Molar

Using the formula above, we can calculate the volume of the solution as follows:

volume = 0.55 moles / 0.46 M = 1.20 L
