Answer:

where:

• A is the wavelength in m.

• h = 6.626 x 10-34Js is Planck's

constant.

• m is the mass of the particle, such as the electron, in kg. The particle must have a mass for this relation to work.

• v is the forward velocity of the particle, in m/s.

Hence, the wavelength is:

6.626 x 10-34J.s

(9.1094 × 10 −³¹kg) (5 × 10³m/s)

We know that 1 J 1 kg. m²/s². So:

Answer:

2.75 × 10⁻⁶ M/s

1.69 × 10⁻⁶ M/s

9.23 × 10⁻⁻⁷ M/s

4.43 × 10⁻⁻⁷ M/s

2.1 × 10⁻⁻⁷ M/s

Explanation:

We have the following information for the isomerization of methyl isonitrile

Time (s)      [CH₃NC] (M)

  0              0.0165

2000          0.0110

5000          0.00591

8000          0.00314

12000         0.00137

15000         0.00074

To calculate the average rate of reaction (r) for each interval, we need to use the following expression:

r = -Δ[CH₃NC]/Δt

Interval 0-2000 s

r = - (0.0110 M-0.0165 M)/2000 s - 0 s = 2.75 × 10⁻⁶ M/s

Interval 2000-5000 s

r = - (0.00591 M-0.0110 M)/5000 s - 2000 s = 1.69 × 10⁻⁶ M/s

Interval 5000-8000 s

r = - (0.00314 M-0.00591 M)/8000 s - 5000 s = 9.23 × 10⁻⁻⁷ M/s

Interval 8000-12000 s

r = - (0.00137 M - 0.00314 M)/12000 s - 8000 s = 4.43 × 10⁻⁻⁷ M/s

Interval 12000-15000 s

r = - (0.00074 M - 0.00137 M)/15000 s - 12000 s = 2.1 × 10⁻⁻⁷ M/s

The average rates of reactions for the time interval between each measurement are

2.75×10⁻⁶ M/s

1.70×10⁻⁶ M/s

9.23×10⁻⁷ M/s

4.43×10⁻⁷ M/s

2.10×10⁻⁷ M/s

From the question,

We are to calculate the average rate of reaction for each of the measurement.

First, we will create a proper table for the data

Time (s)       [CH3NC] (M)

0                    0.0165    

2,000            0.0110

8,000            0.00314      

12,000          0.00137

15,000          0.00074

The average rate of reaction is given by the formula

[tex]Average\ rate\ of\ reaction = \frac{Final\ concentration - Initial\ concentration}{Final\ time - Initial\ time}[/tex]

1.

[tex]Average\ rate\ of\ reaction = \frac{0.0110-0.0165}{2000 -0 }[/tex]

Average rate of reaction = 2.75×10⁻⁶ M/s

2.

[tex]Average\ rate\ of\ reaction = \frac{0.00591-0.0110}{5000 -2000 }[/tex]

Average rate of reaction = 1.70×10⁻⁶ M/s

3.

[tex]Average\ rate\ of\ reaction = \frac{0.00314-0.00591}{8000 -5000 }[/tex]

Average rate of reaction = 9.23×10⁻⁷ M/s

4.

[tex]Average\ rate\ of\ reaction = \frac{0.00137-0.00314}{12000 -8000 }[/tex]

Average rate of reaction = 4.43×10⁻⁷ M/s

5.

[tex]Average\ rate\ of\ reaction = \frac{0.00074-0.00137}{15000 -12000 }[/tex]

Average rate of reaction = 2.10×10⁻⁷ M/s

Hence, the average rates of reactions for the time interval between each measurement are

2.75×10⁻⁶ M/s

Explanation:

Hello there!

In this case, by bearing to to mind the given conditions, it is firstly possible to determine the initial volume of the closed system via the ideal gas equation:

[tex]PV=nRT\\\\V=\frac{2.00mol*0.08206\frac{atm*L}{mol*K}*298.15K}{1.00 atm} \\\\V=48.9L[/tex]

Which is V1 in the Charles' law:

[tex]\frac{T_2}{V_2} =\frac{T_1}{V_1}[/tex]

And of course, T1 is 298.15 (25+273.15). Therefore, by solving for V2 as the final volume, we obtain:

[tex]V_2=\frac{V_1T_2}{T_1}\\\\V_2=\frac{48.9L*(45+273.15)K}{(25+273.15)K} \\\\V_2=52.2L[/tex]

Answer:

-252.5 kJ/mol = ΔH H2O(g)

Explanation:

ΔH Fe2O3 = -825.5kJ/mol

ΔH H2 = 0kJ/mol

ΔH Fe = 0kJ/mol

Based on Hess's law, ΔH of a reaction is the sum of ΔH of products - ΔH of reactants. For the reaction:

Fe2O3(s) + 3 H2(g) →2Fe(s) + 3 H2O(g)

ΔHr = 67.9kJ/mol = 3*ΔH H2O + 2*ΔHFe - (ΔH Fe2O3 + 3*Δ H2)

67.9kJ/mol = 3*ΔH H2O + 2*0kJ/mol - (ΔH -825.5kJ/mol + 3*Δ H2)

67.9 = 3*ΔH H2O(g) + 825.5kJ/mol

-757.6kJ/mol = 3*ΔH H2O(g)

(C) when bonds in food are broken, energy is released

Answer:

LDPE would be the best choice for a hand warmer designed to release heat quickly.

Explanation:

Judging from the graph, the LDPE plastic releases heat quicker than the Latex. (and I also did the gizmo-)

Temperature is a property of matter that represents the amount of energy expended in the motion of the constituent particles.

Matter is any substance that has mass and takes up space by having volume.

The potential to work would be defined as energy.

The definition of motion is still the change in the position and orientation of the body over time.

As a result, the highest temperature of latex is approximately 530°C, while the temperature of LDPE plastic becomes 58°C in the graph above. After 60 minutes, the LDPE plastic will emit less energy toward its surroundings than latex. Latex reaches its highest temperature faster than LDPE plastic.

D. Add an appropriate amount of sodium hydroxide.

Usually, chemical processes require an optimum pH. This is the pH at which the desired chemical conversion gives  the maximum yield.

As we can see, the pH of the system is much higher than the optimum pH. We can decrease the pH to the optimum pH of 5.0 by adding an appropriate amount of  a base such as NaOH.

Hence, the pH can be brought to 5.0 from 6.5 by adding an appropriate amount of NaOH.

Answer:

The alkaline hydrolysis of ester is known as saponification. When ester is heated with aqueous NaOH, sodium salt of acid and alcohol are formed.

The process of saponification of an ester in an alkaline solution. Alcohol and sodium salt of acid are created when the bis heated with aqueous NaOH.

Esters are converted into soap and alcohol through the process of saponification, which uses an aqueous alkali. Fatty acids, which are long-chain carboxylic acids, are the building blocks of soaps. Sodium stearate is a regular soap ingredient.

From the Latin sapo, which signifies soap, the reaction is known as a saponification. The term is derived from the fact that fats were once hydrolyzed into esters to produce soap.

Particularly in the food industry, saponification is significant because it makes it simpler to estimate the amount of free fatty acids present in a specific food product. The quantity of free fatty acid can be determined by measuring how much alkali was needed to neutralize the fat or oil.

Thus,the alkaline hydrolysis reaction of esters is called as saponification.
