Balance the reaction and determine which of the following coefficients

Balance The Reaction And Determine Which Of The Following Coefficients

Answers

Answer 1

Answer:

B. The correct ratio is 3:1:1:3

Explanation:

According to this question, the following chemical equation was given:

CH3COOH + Al(OH)3 → Al(CH3COO)3 + H2O

This equation is obviously not balanced because the number of atoms of each element on both sides of the equation is not equal or the same. To balance the equation, we make use of coefficients as follows:

3CH3COOH + Al(OH)3 → Al(CH3COO)3 + 3H2O

- There are now 6 moles of C on each side

- There are now 15 moles of H on each side

- There are now 9 moles of O on each side

- There is now 1 mole of Al on each side

The correct ratio of each compound is in the order 3:1:1:3

Which of the following processes does NOT facilitate containment?

Answers

Answer:

b is the answr

Explanation:

The correct answer is Option (B) Enrichment of Uranium-235 is done.

What is Containment? Containment is the process of preventing pollution or contamination of the immediate site environment by dust, chemicals, and other materials to prevent corrosion.

What is Corrosion?Corrosion is a natural process that converts a refined metal into a more chemically stable oxide.The degree of containment  is directly proportional to the degree of toxicity present in the corrosion preventive substance being applied.

Why other options are incorrect?Option (A) , (C) , (D) are the options that facilitate containment because these are the processes for preventing contamination.

Hence Option (B) is correct because enrichment of uranium-235 is achieved by the process of conversion So , It does not facilitate containment

There are certain metals that are less reactive compared to standard hydrogen electrode.

So, such metals do not release hydrogen gas in a reaction with dilute acids.

Examples of such metals are:

Two solids of identical mass, A and B, are analyzed using identical calorimeters. Each calorimeter contains the same amount of water and is at room temperature. When the solids are heated to the same initial temperature and placed in their calorimeters, the final temperature of solid A's calorimeter is higher than that of B. What can we infer from this

Answers

Answer:

Specific heat of solid A is greater than specific heat of solid B.

Explanation:

In the calorimeter, as the temperature is increasing, the vibrational kinetic energy will increase and this means that additional amount of energy will be needed to increase the temperature by the same value. Therefore, we can conclude that specific heat increases as temperature increases.

Now, we are told that the final temperature of solid A's calorimeter is higher than that of B.

This means from our definition earlier, Solid A will have a higher specific heat that solid B.

Use the de Broglie's Wave Equation to find the wavelength of a 400 g ball moving at 120 m/s. Please show your work. Note: h = Planck's constant (6.62607 × 10-34 J*s)

Answers

de Broglie's wave equation describes that particles have wave properties. The equation is  

   λ = h/mv

Where λ  is the wave length of the particle (m), h is the Planck's constant (6.62607 x 10⁻³⁴J s), m is the mass of a particle (kg) and v is the velocity (m/s).

λ = ?

h =  6.62607 x 10⁻³⁴ J s

m =200 g = 0.2 kg

v = 20 m/s

By substitution,

   λ  = 6.62607 x 10⁻³⁴ J s / (0.2 kg x 20 m/s)

   λ  = 1.66 x 10⁻³⁴ m

Hence, the wavelength of the 200 g ball 1.66 x 10⁻³⁴ m.

Which of the following is true for the equilibrium constant of a reaction?

It is a ratio of the concentrations in a reaction.
It remains the same at different temperatures.
It is represented by the symbol H.
Its value is always close to 1.

Answers

Answer:

The correct answer is It is a ratio of the concentrations in a reaction.

Explanation:

⇒ It is a ratio of the concentrations in a reaction.

This sentence is true because the equilibrium constant is calculated from the product of the concentration of the reaction products divided into the product of the concentrations of the reactants, each concentration raised by the stoichiometric coefficient. For example, for the following reaction:

aA + bB → cC + dD

The equilibrium constant is expressed as:

[tex]K = \frac{[C]^{c}[D]^{d} }{[A]^{a} [B]^{b} }[/tex]

⇒ It remains the same at different temperatures.

The sentence is false because the equilibrium constant changes with the temperature. In general, an endothermic reaction is favored by the increment of temperature (the equilibrium shifts to the right side) and disfavored with the decrease in temperature (shifts to the left).

⇒ It is represented by the symbol H.

This sentence is false because the equilibrium constant is represented with the letter K.

⇒ Its value is always close to 1.

It is not true because the equilibrium constant can be a number below or above 1.

K < 1 ⇒ there is more concentration of reactants at equilibrium

K > 1 ⇒ there is more concentration of products at equilibrium

Can someone help with this please

Answers

Answer:

see explanations

Explanation:

4NH₃(g) + 5O₂(g) => 4NO(g) + 6H₂O(g)

Ci(NH₃) = 3.5mole/4L = 0.875M

Cf(NH₃) = 1.6mole/4L = 0.400M

Rate-1 => Δ[NH₃]/Δt = |(0.400M - 0.875M)/3min| = 0.158M/s

Rate-2 => 6(Δ[NH₃]/Δt) =  4(Δ[H₂O]/Δt) => 6/4(0.158M/s) = 0.237M/s

Rate-3 => 5(Δ[NH₃]/Δt) =  4(Δ[O₂]/Δt) => 5/4(0.158M/s) = 0.237M/s

_________________________________________________________

NOTE: When setting up comparative rate expressions for a given reaction, set the rates expressions as equal then swap coefficient values.  Then solve for rate of interest and substitute givens.      

example: for NH₃ and H₂O

set rates expressions equal => Δ[NH₃]/Δt =  Δ[H₂O]/Δt then swap and insert coefficients from given rxn ...solve for rate of interest ...

              4NH₃(g) + 5O₂(g) => 4NO(g) + 6H₂O(g)

              =>  6(Δ[NH₃]/Δt) =  4(Δ[H₂O]/Δt)

              =>  Δ[H₂O]/Δt = 6/4(Δ[NH₃]/Δt) = 6/4(0.237M/s) = 0.237M/s

A process which is unfavorable with respect to enthalpy, but favorable with respect to entropy Group of answer choices could occur at high temperatures, but not at lower temperatures. could not occur regardless of temperature. could occur at any temperature. could occur at low temperatures, but not at higher temperatures. none of the above

Answers

Answer:

could occur at any temperature.

Explanation:

The spontaneity of a reaction is what determines whether the reaction will occur or not. A spontaneous reaction occurs easily.

The spontaneity of a reaction is predicted by the sign of ∆G.

When ∆G is positive, the reaction is not spontaneous. When ∆G is negative, the reaction is spontaneous.

Note that;

∆G= ∆H - T∆S

Where;

∆H = Change in enthalpy

∆S = Change in entropy

T= temperature

If ∆H is unfavourable and ∆S is favourable, the reaction can proceed at all temperatures because ∆G will always be negative.

It should be noted that a process that is unfavorable as regards to enthalpy, but favorable with respect to entropy could occur at any temperature.

Enthalpy(∆H) serves as amount of internal energy that a compound has, entropy( ∆S)  on the other hand serves as intrinsic disorder within the system.

However, spontaneity of a reaction determines likely hood of occurrence of a reaction, when the process is spontaneous, it makes the reaction to occurs easily.

We can conclude that whenever enthalpy is unfavourable and entropy of a system is favourable, then the spontaneity will be negative and the reaction will occur at any temperature.

B. -0.0088 M/s
C. -0.141 M/s
D. -0.0352 M/s

Answers

Explanation:

The given chemical equation is:

[tex]2A + 4B -> 2C + 2D[/tex]

The rate of the reaction is 0.0352 M/s.

During the course of the reaction, the rate of reactants decreases, and the rate of products increases.

The rate of disappearance of B is shown below:

[tex]rate=-\frac{1}{4} \frac{d[B]}{dt}[/tex]

So, rate of change of B is :

[tex]rate of change of B =- rate * 4\\=-0.0352 M/s * 4\\=-0.1408M/s\\\\=-0.141M/s[/tex]

Option C.

In the given reaction, rate of change of reactant B is equal to -0.141 M/s.

What is the rate of reaction?

Rate of any chemical reaction defines the speed of the completion of that reaction.

In the question given reaction is:

2A + 4B ----> 2C + 2D

Rate of reaction = 0.0352 M/s.

Rate of the reaction with respect to the reactant B is written as:

Rate = [tex]${\rm{ - }}\frac{{\rm{1}}}{{\rm{4}}}\frac{{\left[ {{\rm{dB}}} \right]}}{{{\rm{dT}}}}$[/tex], where negative sign shows the disappearance of reactant B.

Rate of change of B i.e. [tex]$\frac{{{\rm{dB}}}}{{{\rm{dT}}}}$[/tex] =  4 × (-rate)

[tex]$\frac{{{\rm{dB}}}}{{{\rm{dT}}}}$[/tex] =  4 × (-0.0352) = -0.1408 = -0.141 M/s

Hence, -0.141 M/s is the rate of change of B.
