If a balloon has a volume of 1.696 L at a pressure of 2.11 0 atmospheres, what will be the volume of the balloon if the pressure is increased to 5.067 atmospheres?

Answers

Answer:

I think that the volume will be 1.414

Explanation:

According to the formula of boyle's law P1 V1 = P2 V2

We have to find V2 so:

V2 = P2/P1 V1

By putting the values:

V2 = 5.06/2.11 * 1.696

V2 = 5.06/3.578

V2 = 1.414

Consider this reaction at equilibrium:

2BrNO (g) → 2NO (g)+ Br2 (g)

Predict whether the reaction will shift left, shift right, or remain unchanged after each disturbance.

a. NO is added to the reaction mixture
b. BrNO is added to the reaction mixture
c. Br2 is removed from the reaction mixture
d. Pressure is increased

Answers

Answer:

a. NO is added to the reaction mixture ⇒ to the left

b. BrNO is added to the reaction mixture ⇒ to the right

c. Br₂ is removed from the reaction mixture ⇒ to the right

d. Pressure is increased ⇒ to the left

Explanation:

The reaction at equilibrium is the following:

2BrNO (g) → 2NO (g)+ Br₂ (g)

The left side is the reactants side (2 BrNO) and the right side is the products side (2 NO + Br₂).

a. NO is added to the reaction mixture

NO is a product, in the right side of the equation. If a product is added, the equilibrium will shift to the opposite side, to the left, to form more reactants and compensate for the addition.

b. BrNO is added to the reaction mixture

BrNO is a reactant, in the left side of the equation. If a reactant is added to a reaction at equilibrium, more product will be formed in compensation. Therefore, the equilibrium will shift to the right.

c. Br₂ is removed from the reaction mixture

Br₂ is a product, in the right side. If it is removed, the system will compensate for the remotion by forming more product, so the reaction will shift to the right.

d. Pressure is increased

Since both reactants and products are in the gas phase, the equilibrium is affected by pressure. If pressure is increased, the equilibrium will shift to the side of the reaction with the fewest number of moles. The reactants side (left) has 2 moles of BrNO while the products side (right) has 3 moles (1 mol NO + 1 mol Br₂ = 3 moles of gas). Therefore, the reactants side has the fewest number of moles, so the equilibrium will shift to the left.

How to solve for K when given your anode and cathode equations and voltage

Answers

Answer:

See Explanation

Explanation:

In thermodynamics theory the Free Energy (ΔG) of a chemical system is described by the expression ΔG = ΔG° + RTlnQ. When chemical system is at equilibrium ΔG = 0. Substituting into the system expression gives ...

0 = ΔG° + RTlnKc, which rearranges to ΔG° = - RTlnKc.  ΔG° in electrochemical terms gives ΔG° = - nFE°, where n = charge transfer, F = Faraday Constant = 96,500 amp·sec and E° = Standard Reduction Potential of the electrochemical system of interest.

Substituting into the ΔG° expression above gives

-nFE°(cell) = -RTlnKc => E°(cell) = (-RT/-nF)lnKc = (2.303·R·T/n·F)logKc

=> E°(cell) = (0.0592/n)logKc = E°(Reduction) - E°(Oxidation)

Application example:

Calculate the Kc value for a Zinc/Copper electrochemical cell.

Zn° => Zn⁺² + 2e⁻  ;    E°(Zn) = -0.76 volt  

Cu° => Cu⁺² + 2e⁻ ;    E°(Cu) =  0.34 volt

By natural process, charge transfer occurs from the more negative reduction potential to the more positive reduction potential.

That is,

           Zn° => Zn⁺² + 2e⁻ (Oxidation Rxn)

Cu⁺² + 2e⁻ => Cu°             (Reduction Rxn)

E°(Zn/Cu) = (0.0592/n)logKc

= (0.0592/2)logKc = E°(Cu) - E°(Zn) = 0.34v - (-0.76v) = 1.10v

=> logKc = 2(1.10)/0.0592 = 37.2

=> Kc = 10³⁷°² = 1.45 x 10³⁷

Please, I really need help, so I can graduate

Answers

Answer:

See Explanation

Explanation:

The reaction equation is

3H2(g) + N2(g) -----> 2NH3(g)

1)If 1 mole of N2 yields 2 moles of NH3

12 moles of N2 will yield 12 * 2/1 = 24 moles of NH3

2) 3 moles of nitrogen reacts with 1 mole of nitrogen

6 moles of hydrogen will react with 6 * 1/3 = 2 moles of nitrogen

3) The limiting reactant yields the least amount of product

If 1 mole of nitrogen yields 2 moles of NH3

40 moles of nitrogen yields 40 * 2/1 = 80 moles of NH3

If 3 moles of hydrogen yields 2 moles of NH3

30 moles of hydrogen yields 30 * 2/3 = 20 moles of NH3

Hence hydrogen is the limiting reactant

4) Number of moles in 80g of NH3 = 80g/17g/mol = 4.71 moles

3 moles of hydrogen produces 2 moles of ammonia

x moles of hydrogen produces 4.71 moles of ammonia

x = 3 * 4.71/2 = 7.065 moles of hydrogen

Mass = 7.065 moles of hydrogen * 2 g/mol

Mass = 14.13 g of hydrogen

Answers

The statement that is correct about Urban areas is that they have higher temperatures.

Urban Area is a term to refer to cities. Urban areas are characterized by having a developed infrastructure (wide roads, vehicular bridges, wide platforms, tall buildings, residential areas, industrial areas, among others).

Recent studies affirm that urban areas are warmer than surrounding areas; This phenomenon is because the materials with are built buildings, roads, houses, and others, concentrate the sun's rays, increasing the temperature of cities. In addition, the lack of trees deepens this phenomenon, because the trees contribute to cooling by physicochemical processes such as evapotranspiration.

According to the above, it is possible to affirm that urban areas are hotter than their surrounding area because they lack vegetation, and the materials with which it is built contribute to the increase in temperature.

On the other hand, urban areas are characterized by habitat fragmentation, more problems with soil erosion, and less rain infiltration into the soil.

At what pressure would a 5.32 mol Cl2 sample occupy 5.08 L at 181.59 K? please help!!

Answers

Answer: At a pressure of 15.613 atm a 5.32 mol [tex]Cl_{2}[/tex] sample occupy 5.08 L at 181.59 K.

Explanation:

Given: Moles = 5.32 mol

Volume = 5.08 L

Temperature = 181.59 K

Formula used to calculate the pressure is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

[tex]PV = nRT\\P \times 5.08 L = 5.32 mol \times 0.0821 L atm/mol K \times 181.59 K\\P = \frac{5.32 mol \times 0.0821 L atm/mol K \times 181.59 K}{5.08 L}\\= 15.613 atm[/tex]

Thus, we can conclude that at a pressure of 15.613 atm a 5.32 mol [tex]Cl_{2}[/tex] sample occupy 5.08 L at 181.59 K.

here ya go

Explanation:

-

The pH of the solution with a concentration of 7.6 × [tex]10^{-7}M[/tex] [tex]H_{3}O^{+}[/tex]will be 6.12.

What is pH?

The pH of water indicates how acidic or basic it is. The scale runs from 0 to 14, with 7 representing neutrality. Acidity is indicated by a pH less than 7, while a pH greater than 7 denotes a base. The relative number of free hydrogen, as well as hydroxyl ions in water, and hydroxyl ions in water is measured by pH .

It is known that ,[[tex]H_{3}O^{+}[/tex]]=[tex][H^{+} ][/tex]

pH can be calculated by the formula:

[tex]pH = -logH^{+}.[/tex]

Now, put the value of hydrogen ion in above equation

pH = -log[7.6×10^{-7}M]

      = -log(7.6)-log(10^{-7}

       = -0.88+7log 10

       = -0.88 +7

        = 6.12.

Therefore, the pH of the solution will be 6.12.

Help me find out which reaction is balanced

Answers

Answer:The answer is c

Explanation:

The answer is C
Explanation:
Since there are three C’s on the left side, there needs to be three C’s on the right.
The coefficient in front of CO2 is now 3CO2
Next, balance the H’s.
Since there are 8 H’s on the left, there needs to be 8 on the right.
Since H2O already has two H’s you just need to multiply 2 by 4 to get 8 H’s. The coefficient in front of the H2O needs to be 4.
Finally, balance the O’s.
In 3CO2, there are 6 O’s because 3 x 2 = 6.
In 4H2O, there are 4 O’s.
6 + 4 = 10
There are 10 O’s on the right, so there needs to be 10 on the left.
Since O2 already has 2 O’s, you need to multiply it by 5 because 5 x 2 = 10.
The coefficient in front of the O2 is 5.
The coefficient in front of C3H8 is 1 because it is already balanced.
The final balanced equation has the following coefficients:
1, 5, 3, 4

Answers

Answer:

1. 0.82 gram of Ag+

2. 4.79 g of Ag₂O₃S

Explanation:

From the given information:

Total amount of Ag₂O₃S = 2.24 grams

Atomic mass of Ag+ =107.86 g/mole

molar mass of Ag₂O₃S = 295.8  g/mole

The mass of the Silver (Ag) in grams is:

[tex]= Total\ amount \ of \ Ag^+ \times \dfrac{107.86 \ g/mol}{295.8 \ g/mol}[/tex]

[tex]=2.24 \times \dfrac{107.86 \ g/mol}{295.8 \ g/mol}[/tex]

= 0.82 gram of Ag+

2.

Here, the total amount of Ag₂O₃S = unknown

Atomic mass of Ag+ = 107.86 g/mole

molar mass of Ag₂O₃S = 295.8 g/mole

amount of Ag+  = 1.75 g

The mass of Ag₂O₃S = [tex]Total \ amount \ of \ Ag^+ \times \dfrac{295.8 \ g/mol}{107.86\ g/mol}[/tex]

[tex]=1.75 \times \dfrac{295.8 \ g/mol}{107.86\ g/mol}[/tex]
