What volume (ml) of fluorine gas is required to react with 1. 28 g of calcium bromide to form calcium fluoride and bromine gas at stp?

Answers

Answer 1

144 mL of fluorine gas is required to react with 1.28 g of calcium bromide to form calcium fluoride and bromine gas at STP.

What is Ideal Gas Law ?

The ideal gas law states that the pressure of gas is directly proportional to the volume and temperature of the gas.

PV = nRT

where,

P = Presure

V = Volume in liters

n = number of moles of gas

R = Ideal gas constant

T = temperature in Kelvin

Here,

P = 1 atm  [At STP]

R = 0.0821 atm.L/mol.K

T = 273 K  [At STP]

Now first find the number of moles

F₂  +  CaBr₂  →  CaF₂  +  Br₂

Here 1 mole of F₂ reacts with 1 mole of CaBr₂.

So,  199.89 g CaBr₂ reacts with  = 1 mole of F₂

1.28 g of CaBr₂ will react with = n mole of F₂

[tex]n = \frac{1.28\g \times 1\ \text{mole}}{199.89\ g}[/tex]

n = 0.0064 mole

Now put the value in above equation we get

PV = nRT

1 atm × V = 0.0064 × 0.0821 atm.L/mol.K × 273 K

V = 0.1434 L

V ≈ 144 mL

Thus from the above conclusion we can say that 144 mL of fluorine gas is required to react with 1.28 g of calcium bromide to form calcium fluoride and bromine gas at STP.

When 23.5 g HBr(g) reacts with sufficient Cl2(g), 11.8 kJ is evolved.

Calculate the value of △,H for the chemical equation given.

Answers

Answer:
The enthalpy of reaction per mole of HBr for this
reaction = ArH =-40.62 kJ/mole.
Explanation:
2HBr(g) + C12(g) > 2HC|(g) + Br2 (g)
When 23.9 g HBr(g) reacts with sufficient C12(g),
12.0 kJ of heat is evolved, calculate the value of
Ar for the chemical reaction.
Note that ArH is the enthalpy per mole for the
reaction.
Molar mass of HBr (g) = 80.91 g/mol.
Hence, 1 mole of HBr = 80.91 g
23.9 g of HBr led to the reaction giving off 12.0
kJ of heat
80.91 g of HBr will lead to the evolution of (80.91
× 12/23.9) = 40.62 kJ heat is given off.
Hence, 40.62 kJ of heat is given off per 80.91 g
of HBr.
This directly translates to that 40.62 kJ of heat is
given off per 1 mole of HBr
Hence, the heat given off per mole of HBr for
this reaction is 40.62 kJ/mole.
But since the reaction liberates heat, it means
the reaction is exothermic and the enthalpy
change for the reaction (AHrxn) is negative.

The molar absorption coefficient of a substance dissolved in benzene is measured to be 712 L mol-1 cm-1 at 403 nm. Calculate what fraction of the incident light intensity of that wavelength passes through 2.67 mm of a solution of concentration 3.17 mmol/L.

Answers

According to Beer-Lambert's law, the solution allows for the passage of 3/4 of the incoming light intensity at that wavelength.

Calculation:

According to Beer-Lambert's law,

A = ∈ * C * l

A = log(I₀/I)

T = I₀/I

log (I₀/I) = ∈ * C * l

Here,

A= absorbance of the solution

l= path length= 2.67 mm = 0.267 cm (∵ 1mm = 0.1 cm)

T= transmittance

C= concentration of the given solution = 3.17mmol/L = 3.17* 10⁻³ mol/L

I= transmitted light

I₀= incident light

∈= molar absorption coefficient = 712 L mol⁻¹cm⁻¹

A = ∈ * C * l= 712 * 3.17 * 0.267 *10⁻³ = 602.63* 10⁻³ =0.602

T = [tex]10^{-A}[/tex] = [tex]10^{-0.602}[/tex] = 0.25

so, the percentage of transmittance = 0.25 * 100 = 25 %

Therefore, the intensity reduction will be equal to the original radiation intensity less the transmittance.

Give the initial intensity = 100

So, the reduction = 100 - 25 = 75.

Hence the fraction of incident light intencity= 75/100 = 3/4

Therefore the answer is 3/4.

Which main intermolecular force must be overcome to convert liquid nh3 to nh3 vapor?

Answers

Intermolecular hydrogen force must be overcome to convert liquid NH3 to NH3 vapour.

Sublimation is the phase transition of a substance directly from the solid to the gaseous phase without passing through the liquid phase.

There are the 3 forces that exist between the 2 molecules of NH3

1. Dispersion force: these forces exist between any 2 molecules regardless of anything else.

2. Hydrogen bonding: H is directly bonded to the extremely electronegative atom N, O and F, hence is nearly stripped off electron due to the large electronegativity difference. Hydrogen being small atom further reduces in size even allowing it to approach other molecules very closely. Here, N, O, and F gathers more partial negative charge.

Due to the closure approach between the molecule and strong partial charge, hydrogen bonding is generally more important than dipole bond.

3. dipole dipole interaction: NH3 is a polar molecule with a permanent separation of charge. Each molecules behaves like a tiny magnet and has positive and negative poles so 2 NH3 molecules attract each other. Dipole dipole interactions are stronger than dispersion force in the small molecules.

Thus we concluded that the hydrogen bond should overcome to convert NH3 to vapours.

Answers

Pressure is inversely proportional to volume. Therefore, the effect of pressure change is opposite to the effect of volume change. So when more gas is added to the chamber the total pressure of the chamber doesn't increase.

What are the different relations between pressure and volume?As the volume changes, the concentrations and partial pressures of both reactants and products change. As the volume decreases, the reaction shifts to the reaction side with fewer gas particles.As the volume increases, the reaction shifts to the side of the reaction containing more gas particles. As the pressure increases, the equilibrium shifts towards reactions with fewer moles of gas. As the pressure decreases, the equilibrium shifts to the side of the reaction with higher moles of gas.Moreover, the pressure change in the system due to the addition of the inert gas is not limited to this.

Hi I need help and I am willing to give brainliest
Can you help me find the percent yield of SiO2 given the equation of SiCl4 + O2 → SiO2 + Cl2

the starting amount for SiCl4 is 150g and O2 at 200g. the actual yield for SiO2 is 49.2 g.
Thank you for any help

Answers

1. The first step is to convert your given masses into moles. This way, you can see which reactant is in excess and which one is limiting. A good flow of thought would be: kilograms of SiO2/Carbon→ grams SiO2/Carbon→moles SiO2/Carbon.

2. Repeat this step for the carbon reactant.

3. By comparison, we can tell that the carbon reactant is in excess, which means that the SiO2 reactant is limiting. Because of this, we’ll use the amount of SiO2 to find our percent yield. There’s only so much SiO2 that can react with the carbon.

4. You can now calculate the actual and theoretical yields. The theoretical yield is larger than the actual yield because it does not have physical interactions like loss of energy to the environment and friction to interfere with the reaction.

5. Now compare your two values of actual and theoretical. The formula for percent mass is [(Actual yield)/(Theoretical yield)]*100%. Our final answer for this question is the percent yield of the reaction is 90.8% We can interpret this as 90.8% of the SiO2 reacting will produce solid silicon.

A gaseous mixture containing 32.00 g n2 and 16.00 g ne is placed into an 4.00 l vessel at 0.00 °C. What is the pressure of the mixture?

Answers

The pressure of the mixture can be found out adding the Partial Pressure of the gas.

Partial pressure of gas is the pressure if it alone occupied the entire volume of original mixture.

Moles = given mass / molar mass

Given,

Mass of Nitrogen = 32g

Molar Mass of Nitrogen = 28g

Mass of Neon = 16g

Molar Mass of Neon = 20g

Volume of gas = 4L

Temperature of vessel = 0°C = 273K

Partial Pressure of nitrogen = P₁

Partial Pressure of neon = P₂

Moles of nitrogen, n₁= 32/28 = 1.14

Moles of neon, n₂= 16/20 = 0.8

Using Ideal gas equation for Nitrogen,

∴ P₁V = n₁RT

⇒ P₁ (1) = 1.14 × 0.082 × 273

⇒ P₁ = 25.52atm

Using Ideal gas equation for Neon,

∴ P₂V = n₂RT

⇒ P₂ (1) = 0.8 × 0.082 × 273

⇒ P₂ = 17.9 atm

Total pressure of the mixture can be found out by adding the partial pressures of both the gases.

Total pressure P = P₁  + P₂  

P = 25.52 + 17.9 atm

P = 43.42 atm

Hence, total pressure of the mixture is 43.42atm

[tex]{ \qquad\qquad\huge\underline{{\sf Answer}}} [/tex]

Let's solve ~

Initial concentration of weak acid HA = 0.200 M

and dissociation constant ([tex]{ \alpha} [/tex]) is :

[tex]\qquad \sf  \dashrightarrow \: \alpha = \frac{dissociation \: \: percentage}{100} [/tex]

[tex]\qquad \sf  \dashrightarrow \: \alpha = \frac{9.4}{100} = 0.094[/tex]

Now, at initial stage :

[tex] \textsf{ Conc of HA = 0.200 M} [/tex]

[tex] \textsf{Conc of H+ = 0 M} [/tex]

[tex] \textsf{Conc of A - = 0 M} [/tex]

At equilibrium :

[tex] \textsf{Conc of HA = 0.200 - 0.094(0.200) = 0.200(1 - 0.094) = 0.200(0.906) = 0.1812 M} [/tex]

[tex] \textsf{Conc of H+ = 0.094(0.200) = 0.0188 M} [/tex]

[tex] \textsf{Conc of A - = 0.094(0.200) = 0.0188 M} [/tex]

Now, we know :

[tex]\qquad \sf  \dashrightarrow \: { K_a = \dfrac{[H+] [A-]}{[HA]}} [/tex]

( big brackets represents concentration )

[tex]\qquad \sf  \dashrightarrow \: { K_a = \dfrac{0.0188×0.0188}{0.1812}} [/tex]

[tex]\qquad \sf  \dashrightarrow \: { K_a = \dfrac{0.00035344}{0.1812}} [/tex]

[tex]\qquad \sf  \dashrightarrow \: { K_a \approx 0.00195 } [/tex]

[tex]\qquad \sf  \dashrightarrow \: {K_a \approx 1.9 × {10}^{-3} } [/tex]

According to the problem, we have a 0.200 M solution of a weak acid HA that is 9.4% ionized. To find the Ka (acid dissociation constant) for HA, we can use the percent ionization formula:

[tex]\sf \% \: ionization = \dfrac{[H+]}{[HA]initial \times 100}[/tex]

From this formula, we know that [H+] (the concentration of hydrogen ions) is equal to 9.4% of [HA]initial, and [HA]initial is equal to the initial concentration of the weak acid, which is 0.200 M. Solving for [H+], we get:

[tex]\sf [H+] = 0.094 \times 0.200 \: M = 0.0188\: M[/tex]

Now we can use the equation for Ka:

[tex]\sf Ka = \dfrac{[H+][A-]}{[HA]}[/tex]

We don't know the concentration of the conjugate base (A-) at this point, but we can assume that it is equal to [H+] because the weak acid is only slightly ionized. Therefore, we can substitute [A-] = [H+] = 0.0188 M into the equation and solve for Ka:

[tex]\sf Ka = \dfrac{(0.0188)^2}{(0.200 - 0.0188)} = \bold{1.8 \times 10^{-3}}[/tex]

So the answer is [tex]\bold{ B.\: 1.8 \times 10^{-3}}[/tex].

Draw the major product formed in the reaction involving an acid anhydride dissolved in alcohol.

Answers

What is the product of reaction of acid anhydride dissolved in alcohol ?

A symmetrical acid anhydride will undergo a reaction with an alcohol to give an ester and a carboxylic acid. An asymmetrical acid anhydride will undergo a reaction with an alcohol to give two esters and two carboxylic acids.

Alcohols and anhydrides react to produce esters as the main product and a carboxylate as a byproduct. To neutralise any generated acid, the process is often conducted with a base, such as NaOH or pyridine.

The pH at 25°c of a 0. 11 m solution of a weak acid that has ka = 9. 2 × 10−6 is 3.

What is base dissociation constant?

The base dissociation constant is termed as Kb. Throughout a base split into ts constituent ions in water is determined by its base dissociation constant.

Kb = [H+] [A-]/[HA]

Now, let the concentration of [H+] = [A-] = x

Given,

Ka = 9.2 × 10−6.

Firstly we will calculate the value of the concentration of [H+]

pKa = x^2/(0.11-x)

9.2 × 10−6 = x^2/(0.11-x)

x^2 = 1.012 × 10−6

x = 1.002 × 10^−3.

The concentration of [H+] = [A-] = 1.002 × 10^−3.

Now, we will find pH as

pH = -log[H+]

pH = -log(1.002 × 10^−3)

pH = 3

Thus we calculated that the pH of the solution is 3.

The density of aluminum is 2.7 g/cm³. What is the density of aluminum in decagrams/m³?

Answers

Answer:

Density = 0.27 decagrams/cm³

Explanation:

From conversion tables, we know that;

1 g/cm³ = 0.1 decagrams/cm³

We are given;

Density of aluminium = 2.7 g/cm³

Thus;

Density = 2.7 * 0.1

Density = 0.27 decagrams/cm³

Answer:

270000 decagrams/m³

Explanation:

1.

Density=mass/Volume

=2.7g/1cm3

=(2.7/1000)/(1/1000000)

=2.7x1000

Density=2700kg/ m3

= 270000 decagrams/m³

2.

1000g=1kg

1g=1/1000kg

1cm3= ? m3

100cm=1m

1cm=1/100 m

1cm3=1/1000000 m3
