Find The POH For The Following: A 1.34 X 10^-4 M Solution Of Hydrochloric Acid.A) 10.13B) 3.87C) 4D)

Answers

Answer 1

Answer:

A) 10.13 is the answer

Explanation:

Since HCl is a strong acid, its pH can be found by simply plugging it into the equation:

pH = -log[H+]

*H+ is just the concentration you were given*

Now that you have the pH, you just subtract it from 14 to find the pOH

I have attatched my work below. Hope this helps! :^)

Answer 2

To find the pOH of a solution, you can use the formula: pOH = -log10[OH-]

What is pOH?

pOH is a measure of the concentration of hydroxide ions (OH-) in a solution. It is the negative logarithm (base 10) of the hydroxide ion concentration.

In this case, since we have hydrochloric acid (HCl), we need to consider the concentration of hydroxide ions (OH-) produced when HCl dissociates in water.

HCl is a strong acid and completely dissociates, meaning it produces an equal concentration of hydrogen ions (H+) and chloride ions (Cl-) in water. Since there are no hydroxide ions produced, the concentration of hydroxide ions is 0.

Therefore, the pOH of a hydrochloric acid solution is 0, and none of the options provided (A, B, C, D) is the correct answer.

Calcule la molaridad de una solución acuosa de ácido sulfúrico (H₂SO₄) que se preparó al mezclar, en un recipiente aforado, 4 moles del ácido con suficiente agua hasta completar 8 litros de solución. *
0.4
0.6
0.3
0.5

Answers

Considerando la definición de molaridad, la molaridad de una solución acuosa de ácido sulfúrico (H₂SO₄) es 0.5 [tex]\frac{moles}{litro}[/tex].

La molaridad es una medida de la concentración de un soluto en una disolución que se define como el número de moles de soluto que están disueltos en un determinado volumen.

La molaridad de una solución se calcula dividiendo los moles del soluto por el volumen de la solución:

[tex]Molaridad=\frac{numero de moles de soluto}{volumen}[/tex]

La Molaridad se expresa en las unidades [tex]\frac{moles}{litro}[/tex].

En este caso, sabes que una solución acuosa se preparó al mezclar 4 moles del ácido con suficiente agua hasta completar 8 litros de solución. Entonces, sabes que:

número de moles de soluto= 4 molesvolumen= 8 litros

Reemplazando en la definición de molaridad:

[tex]Molaridad=\frac{4 moles}{8 litros}[/tex]

Resolviendo:

Molaridad= 0.5 [tex]\frac{moles}{litro}[/tex]

Finalmente, la molaridad de una solución acuosa de ácido sulfúrico (H₂SO₄) es 0.5 [tex]\frac{moles}{litro}[/tex].

What is the theoretical yield of carbon dioxide? 0. 993 g 2. 98 g 3. 65 g 8. 93 g.

Answers

Answer:

The answer is C.

Explanation:

i got a 100 on the test

The theoretical yield of carbon dioxide, CO₂ obtained from the reaction is 8.93 g

We'll begin by calculating the mass of citric acid, H₃C₆H₅O₇ that reacted and the mass of carbon dioxide, CO₂ produced from the balanced equation.

H₃C₆H₅O₇ + 3NaHCO₃ —> 3CO₂ + 3H₂O + Na₃C₆H₅O₇

Molar mass of H₃C₆H₅O₇ = (3×1) + (12×6) + (5×1) + (7×16) = 192 g/mol

Mass of H₃C₆H₅O₇ from the balanced equation = 1 × 192 = 192 g

Molar mass of CO₂ = 12 + (2 × 16) = 44 g/mol

Mass of CO₂ from the balanced equation = 3 × 44 = 132 g

From the balanced equation above,

192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂

Finally, we shall determine the theoretical yield of CO₂. This can be obtained as follow:

From the balanced equation above,

192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂.

Therefore,

13 g of H₃C₆H₅O₇ will react to produce = (13 × 132) / 192 = 8.93 g of CO₂.

Thus, the theoretical yield of CO₂ is 8.93 g

If two trucks are moving at the same speed, but truck A has a mass of 3,000 kg, and truck B has a mass of 4,500 kg, what statement is true?

Question 3 options:

Truck B will have a greater stopping distance.


Truck A will have a greater stopping distance.


Truck B has less kinetic energy.


Truck A has greater kinetic energy.

Answers

We want to compare the kinetic energy of two moving objects, we will see that the correct option is the first one:

"Truck B will have a greater stopping distance."

Remember that the kinetic energy of an object of mass M and velocity V is given by:

[tex]E = \frac{M}{2}*V^2[/tex]

Here we know that truck A and truck B have the same velocity, but truck B has a larger mass.

Knowing that the kinetic energy increases linearly with the mass, we can conclude that truck B has the largest kinetic energy.

Because of this, we can also conclude that truck B will have a greater stopping distance, this happens because there is more kinetic energy that must be dissipated.

So the correct option is the first one:

"Truck B will have a greater stopping distance."

do you think organisms who live in the artic would survive in the desert? Do you think organisms in the desert would survive in the artic? Why or why not?

Answers

Answer:

I'd say probably not

Explanation:

Organisms have evolved to survive and thrive in particular environmental conditions, specifically focusing on food supply, temperature, terrain, etc.. Therefore, desert animals would not be equipped with the insulation to survive in cold climates like the artic, and would freeze to death, and artic animals would most likely die from heat exhaustion in the desert. Additionally, fish, which is a main food source for articles animals, are not available in the desert, and it's the same case for desert animals in the artic. Finally, those organisms' enzymes and proteins, which make up their being and are the reason they can function, are only optimal in the temperature range in which they normally live; therefore, switching to such drastically different climate would result in their enzymes denaturing and their cell and eventual organism death.

Group 3 element aluminium.
Give a reason why, in terms of electronic structure.

Answers

Answer:

Atomic orbital energy ordering.

Explanation:

The transition metals constitute the d-block. The answer to your question has to do with the energy ordering of atomic orbitals. Specifically, the 3s orbitals are lower in energy than 3p, which are lower in energy than 4s, which are lower in energy than 3d (remember the principal quantum number for d orbitals is one minus the principle quantum number of the shell so n = 4 level's d orbitals are the 3d orbitals). According to the Aufbau principle, atomic orbitals are filled with electrons from the lowest energy up. So the orbitals would have to be filled in the order of 3s, 3p, 4s, and then 3d. Magnesium has its last valence electron residing in the 3s orbital and Aluminum has its last valence electron residing in the first 3p orbital (specifically the 3px orbital, which is aligned horizontally in the 3d plane. The three p orbitals for all principle quantum levels are px, py, pz, with the x, y, z describing the orientation in the 3d plane). The 3d has not yet been reached in terms of energy ordering. This is why there are no transition elements between magnesium and aluminum, in terms of electronic structure.
