how many moles of naoh are contained in 15.2l of a 0.205m naoh solution? multiple choice 125 moles naoh 0.0134 moles naoh 3.12 moles naoh 74.1 moles naoh 0.0779 moles naoh

Answers

Answer 1

3.12 moles NaOH  are contained in 15.2l of a 0.205m NaOH solution

15.2 x 0.205 = 3.116 moles. By rearranging the equation, you must first determine how many moles are there in this solution. False. Molarity (M) x Volume (L) equals 15.2 x.205, or 3.12 moles.

Molarity (M), which is determined by dividing the solute's mass in moles by the volume of the NaOH  solution in liters, is the most often used unit to represent NaOH solution concentration: liters of solution/moles of solute equals M. One liter of a NaOH  solution with a 1.00 molar concentration (1.00 M) contains 1.00 moles of solute.

In his law of viscosity, Sir Isaac Newton described Newtonian fluids. In conclusion, he discovered that Newtonian fluids have a constant viscosity/flow and that changes in temperature or pressure only cause these fluids' flow behavior to vary. This kind of fluid is not affected by stress.

Water is a good example. Its viscosity is affected by temperature. It becomes a solid at 0 degrees Celsius and a gas at 100 degrees Celsius, but between those two points, it behaves normally and maintains a constant viscosity. Applying stress does not change the viscosity of water.

Answers

Answer: The correct answer is 4.956 * 10^7.

Explanation:

For Electrostatic force,

Given qA =1.2 × 10∧-6 C (Since 1 micron = 10∧-6)

qB=0.92 ×10∧-6 C Since 1 micron = 10∧-6)

r = 4.8m

Electrostatic force = (K×qA×qB)÷r∧2 where K is Coulomb's constant or electrostatic constant =8.98755×10∧9

Therefore Electrostatic energy =(8.98755×10∧9×1.2×0.92×10∧-12)÷4.8∧2

                                                   =0.00043065 N ················ eq1

Now for Gravitational force,

mA=2Kg ,mB=1.5Kg ,r=4.8m,G is Gravitational constant =6.67408 × 10-11 N m2 kg-2

Gravitational force=(G×mA×mB)÷r∧-2

                               =(6.67408 × 10-11 ×2×1.5)÷4.8∧-2

                                 =0.869021875 ×10∧-11 N...............eq2

Ratio of electric and gravitational force between ‘A’ and ‘B’ = eq1÷eq2

                                                                                 =49555714.5785

                                       

Electrostatic force occurs due to interaction either between like charges that is either between positive-positive or negative negative charges or between unlike charges like positive-negative. Its strength  depends on the charges and the distance between the charges which decreases as the distance increases.

Gravitational  force occurs due to the fact every particle attracts each and every other particle in the universe. Its strength  depends on the mass  and the distance between the particles which decreases as the distance increases.

What can we say about the temperature change of a sample of water when the value of q is negative?
The temperature of the water increased.
The temperature of the water decreased.
It depends on whether mass and specific heat values are positive or negative.

Answers

The temperature of the water increased when the value of q(specific heat capacity) is negative.

Explanation of Specific Heat Capacity

The hydrogen bonding in water is the cause of its high specific heat capacity, which we can explain. The water molecules must shake in order for the numerous connected hydrogen bonds to raise the temperature of the liquid. Because there are so many hydrogen bonds, it takes more energy for the water molecules to break. Similarly to this, it takes some time for warm water to cool down. The temperature drops as heat escapes and the vibrational motion of water molecules slows. The warmth released balances the chilling impact of the heat loss from the liquid water.

Specific Heat of Water

The specific heat capacity (Cp) of a liquid at atmospheric pressure and temperature is roughly 4.2 J/g°C. This suggests that to increase 1 gramme of water by 1 degree Celcius, 4.2 joules of energy are required. Actually, this Cp number is rather high. The specific heat of liquid water, also known as the specific heat capacity of liquid water, is 1.9 J/g°C..

(a) can a hydrogen atom in the ground state absorb a photon of energy less than 13.6 ev?

Answers

Yes, a hydrogen atom in the ground state can absorb a photon of energy less than 13.6 ev.

The wavelength of the matter waves that make up an electron orbit around a nucleus is the same as the radius of the orbit. Any fractional number would not fit the circle of the electron orbit, but a whole number of wavelengths might. Atomic excitations, in which the electrons take in a photon to enter a higher energy state, are another process that an atom goes through. As a result, electrons' wavelength can shift, which also causes the electron's orbit to alter. The relationship between an electron's energy and wavelength is inverse. An electron in the ground state can therefore absorb a photon with energy equal to the energy difference between the ground state energy and excited state energy during atomic excitation.

What is the resulting pH?Part B: More strong base is added until the equivalence point is reached. What is the pH of this solution at the equivalence point if the total volume is 71.0 mL ?Express the pH numerically to two decimal places.

Answers

Part A : pH = 4.77 when a  solution is made by titrating 8.00 mmol (millimoles) of HA and 2.00 mmol of the strong base. Part B : pH = 9.15 if More strong base is added until the equivalence point is reached in solution of total volume 71.0mL.

Part A :

Ka value of 5.61 x 10 -6

pKa = -log Ka = 5.25

And the reaction:

HA + OH- = A- + H0

excess millimoles HA = 8.00 - 2.00 = 6.00

mmol A- formation = 2.00

pH = 5.25 + log 2.00/6.00

=5.25 + log 0.333

=4.77

Part B:

A- millimoles formed at the equivalence point = 8.00 => 8.00 x 10^-3 mol

[A-]= 8.00 x 10^-3 mol/ 0.0710 L=0.113 M

A- + H0 <=> HA + OH-

Kb = Kw/Ka = ​​1.0 x 10^-14 / 5.61 x 10^-6 = x^2/ 0.113-x

1.78*10^-9 = x^2/0.113-x

Due to the small value of Kb, we can write 0.113-x = 0.113.

1.78*10^-9 = x^2/0.113

X = 1.42*10^-5

x = [OH-] = 1.42 x 10^-5M

pOH = -log[OH-] = 4.85

and pH + pOH = 14

Therefore pH = 14-4.85

pH = 9.15

c. 0.0644 M
d. 0.489 M
e. 4.95 M

Answers

Option (b) is correct. The molarity of the resulting solution is 0.652 M. This is calculated using the expression of ideal gas equation and molarity.

12.7 l of argon at 33°c and 735 torr are dissolved in enough water to give a final volume of 0.750l. so,

P = 735.0 torr

 = (735.0/760) atm.

 = 0.9671 atm.

V = 12.7 L

T = 33.0 o C

 = (33.0+273) K

 = 306 K

We can find the  number of moles using ideal gas equation. The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions. The ideal gas equation is,

         P * V = n*R*T

        0.9671 atm. * 12.7 L = n * 0.08206 atm. L/mole . K * 306 K

        n = 0.4891 mole

Now, we will calculate Molarity. Molarity or molar concentration is the number of moles of solute per liter of solution, which can be calculated using the following equation,

Molarity = number of mole / final volume

 = 0.4891 mole / 0.750 L

FILL IN THE BLANK. of the following, only ________ is a valid unit for reaction rate.

Answers

Every item in motion contains kinetic energy, which is equal to 1 / 2 mv 2, where m is the object's mass and v is its speed. The electromagnetics equation is (6 10 - 19 C).

Electron velocity (V) = 1/(mqv2) An electron's energy is 0 while it is infinitely far from the nucleus, but as it approaches closer, it is bounded from the nucleus and its energy changes to negative. Energy increases to a bigger negative value as the distance decreases because it is inversely proportional to equation. The speed of an electron in the ground state of a hydrogen atom is 1 137 times faster than the speed of light.

Answers

When the definition of atomic mass, isotopes, and average atomic mass of an element are kept in mind, the average mass of the metal is 20. 2. Exactly how does atomic mass mean?

The atomic mass of an element is its average atomic mass given in number of atoms (amu, also known as daltons, D). The atomic mass of a particular element is its arithmetic mean across all of its isotopes.

What does atomic mass look like?

An average atomic value is a number that is the only mass of an isotope of carbon-12. The carbon-12 reference standard is used to represent the mass of any isotope of any element. For illustration, the weight of an atom of information as appropriate is 4.0026 amu.

Compare and contrast biological and non biological
methods of metal extraction

Answers

Biological and non-biological methods of metal extraction refer to the different ways in which metals can be extracted from ore deposits in the ground. Biological methods, also known as biomining, use microorganisms to extract metals from ores. These microorganisms, such as bacteria and fungi, can break down the chemical bonds in ores and release the metals they contain, which can then be extracted and purified. Non-biological methods, on the other hand, use physical or chemical processes to extract metals from ores. These methods can include roasting, smelting, and leaching, and they do not require the use of living organisms.

One key difference between biological and non-biological methods of metal extraction is the speed at which they can extract metals. Biological methods are generally slower than non-biological methods, but they are also often more environmentally friendly, as they do not produce as much waste or pollution. Non-biological methods, on the other hand, can be faster and more efficient, but they can also be more harmful to the environment.

Another difference between the two types of metal extraction methods is the types of ores that they can be used on. Biological methods are typically more effective on sulfide ores, which are ores that contain sulfur. Non-biological methods, on the other hand, are often more effective on oxide ores, which are ores that contain oxygen.

Overall, biological and non-biological methods of metal extraction are two different approaches to extracting metals from ores. While both methods have their advantages and disadvantages, they are both important tools in the field of mining and metallurgy.
