If 1. 3618 moles of AsF3 are allowed to react with 1. 0000 mole of C2Cl6, what would be the theoretical yield of AsCl3, in moles

Answers

Answer 1

Answer:

AsF3:C2CI6

4:3

1.3618 moles: 1.02135 moles(1.3618÷4×3)

C2CI6 is the limting reagent

So the number of moles for AsCI3 is 0.817 moles( number of moles of the limting reagant) ÷3 ×4 (according to ratio by balancing chemical equation)=1.09 moles(3 s.f.)

or

Balanced equation

4AsF3 + 3C2Cl6 → 4AsCl3 + 3C2Cl2F4

Use stoichiometry to calculate the moles of AsCl3 that can be produced by each reactant.

Multiply the moles of each reactant by the mole ratio between it and AsCl3 in the balanced equation, so that the moles of the reactant cancel, leaving moles of AsCl3.

What is a theoretical yield?

The theoretical yield is the product formation from the complete modification of the limiting reagent in a chemical reaction.

The balanced chemical reaction is shown as,

[tex]\rm 2FePO_{4} + 3Na_{2}SO_{4} \rightarrow Fe_{2}(SO_{4})_{3} + 2Na_{3}PO_{4}[/tex]

Moles of ferric phosphate is calculated  as:

From the reaction,

[tex]\dfrac{1 \;\rm mol \; Fe_{2}(SO_{4})_{3} }{2 \;\rm mol \; FePO_{4}}&= \dfrac{\rm X}{ 0.1326 \;\rm mol \; FePO_{4}}[/tex]

Solving for X:

[tex]\begin{aligned} \rm X &= (\dfrac{0.1326}{2}) \times 1 \rm \; mol\\\\&= 0.0663 \;\rm mol \;Fe_{2}(SO_{4})_{3}\end{aligned}[/tex]

Calculating mass from moles:

[tex]\begin{aligned}\rm mass &= \rm moles \times molar \rm \; mass\\\\&= 0.0663 \;\rm mol \times 399.88 \;\rm g/mol \\\\&= 26.51\;\rm g\end{aligned}[/tex]

What current (in a) is required to plate out 2. 96 g of nickel from a solution of ni2 in 27. 12 minutes?

Answers

The current required to plate out 2.96 g of nickel from the solution of Ni²⁺ in 27.12 minutes is 5.95 A

Balanced equation

We'll begin by writing the balanced equation showing the number of faraday required to plate nickel. This is given below

Ni²⁺ + 2e —> Ni

Molar mass of Ni = 59 g/mol

Mass of Ni from the balanced equation = 1 × 59 = 59 g

Number of faraday = 2 F

1 faraday = 96500 C

2 faraday = 2 × 96500 = 193000 C

SUMMARY

From the balanced equation above,

59 g of Nickel was deposited by 193000 C of electricity

How to determine the quantity of electricity

From the balanced equation above,

59 g of Nickel was deposited by 193000 C of electricity

Therefore,

2.96 g of Nickel will be deposited by = (2.96 × 193000) / 59 = 9682.71 C of electricity

How to determine the current Quantity of electricity (Q) = 9682.71 CTime (t) = 27.12 mins = 27.12 × 60 = 1627.2 sCurrent (I) =?

I = Q / t

I = 9682.71 / 1627.2

I = 5.95 A

https://brainly.com/question/24795850

The current required to plate out 2. 96 g of nickel from a solution of ni2 in 27. 12 minutes is 5.95 ampere.

What is current?

Current is a charged particle moving through an electrical conductor.

The equation is [tex]\rm Ni^2^+ + 2e = Ni[/tex]

step 1: calculate the mass of Ni

Molar mass of Ni is 59 g/mol

59 × 1 = 59 g

Step2: calculate the number of Faraday

no. of Faraday is 2F

1 Faraday = 96500 C

then, 2 Faraday is equal to 2 × 96500 = 193000 C

Step 3: calculate the quantity of electricity

59 g of Nickel is deposited by, 193000 C of electricity

So, for 2.96 g of nickel

[tex]\dfrac{2. 96\;g \times 193000}{59} = 9682.71 \;C[/tex]

Step4: calculate the current:

Electricity Q = 9682.71 C

Time = [tex]27.12 \times 60 = 1627.2 \;s[/tex]

To find current

[tex]I = \dfrac{Q}{t} \\\\I = \dfrac{9682.71 }{1627.2}\\I = 5.95 A[/tex]

Thus, the current required is 5.95 ampere.

Explain how matter is conserved on a molecular scale when ionic compounds dissociate in solution ?

Answers

When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process represents a physical change known as dissociation.


Hope this helps ^v^

The matter is conserved on a molecular scale when ionic compounds dissociate in solution in the form of solvated ions.

What are ionic compounds?

Ionic compounds are those compounds which are formed due to high attractive electrostatic force between the cation (positively charged ion) and anion (negatively charged ion) of any substance.

When a solid ionic compound dissolve in any solution then they will shows dissociation reaction as a result of which we get their ions uniformly distributed in the solution. As water molecule is also polar and ionic compounds are also polar that's why they show complete dissolving in water due to dissociation.

Hence in molecular scale we get it in the form of solvated ions.

A solution is defined as the homogeneous mixture which contain one or more solutes in a solvent. The factors which affect the solubility are temperature and pressure. Here individual salt crystals dissolve faster.

What is solubility?

The maximum amount of solute which can dissolve in a given quantity of the solvent at a certain temperature is defined as the solubility. It is defined as the property exhibited by a material to dissolve in a given solvent.

The powdered salt found to dissolves faster in a solvent than the salt of larger size. The rate of dissolving is affected by the size of the solute. The faster the solute dissolves if its size is smaller. So the  individual salt crystals dissolves faster.

In most cases, generally the solubility found to decrease with the increase of temperature. When the temperature increases, the kinetic energy of the molecules increases and thereby decreases the intermolecular force of attraction. The increase in the process of agitation decreases the solubility.

An extra shell, which means further distance between those electrons in the valence shell and the nucleus. Ionisation energy refers to the energy required to remove valence electrons. There will be more energy required if the valence electrons are closer to the nucleus that have a positive charge, because of more attraction. If there is an extra shell, there is further distance, less attraction and hence less energy required.

A gas has a pressure P at 27 °C. To calculate its pressure at 57°C we use an expression derived from Gay-Lussac's law:

C) P2 = (300/330) P

What does Gay-Lussac's law state?

Gay-Lussac's law states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas when the volume is kept constant.

Mathematically, it can be written as:

P/T = k

A gas has a pressure P at 27 °C and we want to find the expression to calculate its pressure at 57°C.

Step 1: Convert the temperatures to the Kelvin scale.

We do so by summing 273.15.

K = 27 + 273.15 = 300 K

K = 57 + 273.15 = 330 K

Step 2: Apply Gay-Lussac's law.

P2/330 = P/300

P2 = (300/330) P

What is the heat of reaction?

The heat or enthalpy of a reaction is the amount of heat evolved or absorbed when reactant molecules when reactants form products.

Considering the given reaction:

2 Al2O3(s) -> 2 Al(s) + 3 O2(g)

The heat of formation of aluminum oxide is -1669.8 kJ/mol.

The heat of the reaction of the decomposition of aluminium oxide is calculated as follows:

Heat of reaction = Heat of formation of products - Heat of formation of reactants

Heat of reaction = {3 × ΔHf°O2 (g) + 2 × ΔHf° Al(s)} - 2 × ΔHf° Al2O3 (s)

Since the standard enthalpy of formation,ΔHf°, of an element in its most stable form is equal to zero.

ΔH°rxn = (3 × 0 + 2 × 0) - 2 × -1669.8 kJ/

Explain why air resistance is a contact force and gravity is a non-contact force.

Answers

Answer:

The air resistance is a special type of frictional force that acts upon objects as they travel through the air. The force of air resistance is often observed to oppose the motion of an object. This force will frequently be neglected due to its negligible magnitude (and due to the fact that it is mathematically difficult to predict its value). It is most noticeable for objects that travel at high speeds (e.g., a skydiver or a downhill skier) or for objects with large surface areas. Air resistance is a contact force.

The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object. All objects upon earth experience a force of gravity that is directed "downward" towards the center of the earth. Gravitational force is considered to be a non-contact force because it is an attracting force which does not include contact between the objects to exert force
