156.975kj heat is required to raise the temperature of 0.50 kg of liquid water from 15℃ to 90℃.

The term specific heat is defined as the quantity of heat required to increase the temperature of one gram of a substance by one Celsius degree.

To calculate the energy required to raise the temperature of any given substance,

Given:

The mass of the material, m

The temperature change that occurs, ΔT

The specific heat capacity of the material, c (which you can look up). This is the amount of heat required to raise 1 gram of that substance by 1°C.

Q = m × c × ΔT

For water, the value of c is 4.186 J/g°C

Therefore,

Q = 500 × 4.186 × 75

= 156,975j

= 156.975kj

Thus, 156.975kj heat is required to raise the temperature of 0.50 kg of liquid water from 15℃ to 90℃.

Answer:

Solubility product constant

Solubility

Saturated Solution

Common ion effect

Molar Solubility

Explanation:

If i have the ionic compound KNO3 for instance; the solubility product of the compound is the  product of the molarities of the dissolved ions, raised to a power equal to the ion's coefficient in the balanced chemical equation.

E.g

KNO3(s) ------> K^+(aq) + NO3^-(aq)

Ksp = [K^+] [NO3^-]

The solubility of any given substance is defined as mass of the substance in grams that dissolves in 100 mL of water.

A saturated solution is one that has dissolved the maximum amount of  solute at a given temperature. If more solute is added, it will not dissolve.

If i add AgCl to a solution of HCl, the solubility of AgCl in HCl solution is found to be less than its solubility in pure water because of the presence of a common Cl^-. Hence, common ion effect is a decrease in the solubility of an ionic compound as a result of the addition of a common ion to the solution.

The molar solubility of a substance is defined as the maximum number of moles of a substance that will dissolve in 1 L of solution.

The terms used to describe the followings are:

The molarity is the concentration unit used for the determination of the moles of solute in the liter of solution.

For example:

[tex]\rm H_2A\;\rightarrow\;2H^+\;+A^-\\Solubility\;product\;constant=[H^+]^2[A^-][/tex]

The solution with the maximum amount of salt dissolved at a certain temperature is termed the saturated solution. Further addition of the solute results in the precipitation of the solute in the solution.

The effect raised with the addition of the common ions is termed the common ion effect.

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)

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

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

Answer:

1.32 moles.

Explanation:

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

Density of Al = 2.70 g/cm³

Volume of Al = 13.2 cm³

Number of mole of Al =.?

Next, we shall determine the mass of Al.

This can be obtained as follow:

Density of Al = 2.70 g/cm³

Volume of Al = 13.2 cm³

Mass of Al =?

Density = mass / volume

2.7 = mass of Al / 13.2

Cross multiply

Mass of Al = 2.7 × 13.2

Mass of Al = 35.64 g

Finally, we shall determine the number of mole of Al. This can be obtained as follow:

Mass of Al = 35.64 g

Molar mass of Al = 27 g/mol

Number of mole of Al =?

Mole = mass / molar mass

Number of mole of Al = 35.64 / 27

Number of mole of Al = 1.32 moles

Thus, 1.32 moles of aluminum are present in the block of the metal.

Answer:

3.1 * 10^-14

Explanation:

Note that E°cell = 0.0592/n log K

We can obtain E°cell from the standard reduction potentials of cadmium and hydrogen

Anode reaction

H2(g) ----> 2H+ + 2e

Cathode reaction

Cd^2+(aq) + 2e -----> Cd(s)

E°cell = E°cathode - E°anode

E°cathode = –0.40 V

E°anode = 0 V

E°cell =  –0.40 V - 0 V

E°cell = –0.40 V

E°cell = 0.0592/n log K

Where n=2 electrons transferred

–0.40 = 0.0592/2 log K

–0.40 = 0.0296 log K

log K = –0.40/0.0296

log K = -13.5135

K = Antilog ( -13.5135)

K = 3.1 * 10^-14

The molarity of a solution containing 20moles of NaCl dissolved in 10 liters of water is 2 mol/L.

Molarity of any solution will be calculated by using the below formula:
M = n/V, where

n = moles of solute = 20 mol

V = volume of solution or solvent = 10 L

On putting values on above equation, we get

M = 20 / 10 = 2M

Hence required molarity of NaCl is 2 M.

Answer: In an endothermic reaction for whom the value of [tex]\Delta H[/tex] is positive has potential energy of the products greater than the potential energy of the reactants.

Explanation:

A chemical reaction in which heat energy is absorbed is called an endothermic reaction. For an endothermic reaction the value of [tex]\Delta H[/tex] is positive.

A chemical reaction in which heat energy is released is called an exothermic reaction. For an exothermic reaction the value of [tex]\Delta H[/tex] is negative.

In an endothermic reaction, heat energy is absorbed by the reactant molecules due to which the energy of products tend to increase. As potential energy is the energy acquired by a substance due to its position.

Therefore, we can conclude that in an endothermic reaction for whom the value of [tex]\Delta H[/tex] is positive has potential energy of the products greater than the potential energy of the reactants.
