Answer:

0.125 g

Explanation:

From the question given above, the following data were obtained:

Original amount (N₀) = 1 g

Number of half-lives (n) = 3

Amount remaining (N) =?

We can obtain the amount of the substance remaining by using the following formula:

N = 1/2ⁿ × N₀

N = 1/2³ × 1

N = ⅛ × 1

N = 0.125 × 1

N = 0.125 g

Thus, 0.125 g of the substance will remain after 3 half-lives.

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

5,000            0.00591      

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

1.70×10⁻⁶ M/s

9.23×10⁻⁷ M/s

4.43×10⁻⁷ M/s

Answer:

5.51g

Explanation:

Using the following formula:

Q = m × c × ∆T

Where;

Q = amount of heat in Joules

m = mass/weight of Aluminum

c = specific heat of Aluminum (0.900 J/g°C)

∆T = change in temperature.

Based on the information given in this question, Q = 175.6 joules, ∆T = 35.4°C, c = 0.900 J/g°C.

Using, Q = m × c × ∆T

175.6 = m × 0.900 × 35.4

175.6 = 31.86m

m = 175.6/31.86

m = 5.51g

The weight of the aluminum sample is 5.51g.

The rock cycle basically tell you how the different types of rocks are related to each other and tells how they change over time.

Hope this helped!!!

Answer:

The rock cycle is the process by which rocks of one kind change into rocks of another kind. Metamorphic rock is igneous or sedimentary rock that has been heated and squeezed. It can erode into sediment or melt into a hot substance known as refordium. It is formed under extreme pressure and temperature deep inside mountain chains. For example, sedimentary rock shale becomes slate when heat and pressure are added, thus transforming it into another state of rudementury.

• A is the wavelength in m.

• h = 6.626 x 10-34Js is Planck's

• 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:

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.

Answer:

7.14%

Explanation:

From the question,

percentage by mass hydrogen in C₄H₈O₃ (h)   = mass of hydrogen present in C₄H₈O₃(m)/molar mass of C₄H₈O₃ (m')

h = (m'/m)×100..................... Equation 1

Given: m' = (14×4)+(1×8)+(16×3) = 56+8+48 = 112 g, m =  (1×8) = 8 g

Substitute these values into equation 1

h = (8/112)×100

h = 7.14%.

Hence the percentage of hydrogen in 70 g of C₄H₈O₃ is 7.14%

Answer:

[tex]V_2=52.2L[/tex]

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]

Best regards!
