Give the value of the quantum number ℓ, if one exists, for a hydrogen atom whose orbital angular momentum has a magnitude of 6√(h/2π).

Answers

Answer 1

Answer:

For this angular momentum, no quantum number exist

Explanation:

From the question we are told that

   The magnitude of the angular momentum is  [tex]L = 6\sqrt{\frac{h}{2 \pi} }[/tex]

The generally formula for Orbital angular momentum is mathematically represented as

           [tex]L = \sqrt{(l * (l + 1)) } * \frac{h}{2 \pi}[/tex]

Where [tex]l[/tex] is the quantum number

now  

We can look at the given angular momentum in this form as

      [tex]L = 6\sqrt{\frac{h}{2 \pi} } = \sqrt{36} * \sqrt{\frac{h}{2 \pi}} }[/tex]

comparing this equation to the generally equation for Orbital angular momentum

     We see that there is no quantum number that would satisfy this equation

Which describes the boundary where earthquake activity occurs along rift valleys? divergent boundary in the ocean divergent boundary on land convergent boundary in the ocean divergent boundary on land

Answers

Answer:

Divergent boundary on land

Explanation:

A rift valley is a lowland region that forms where Earth’s tectonic plates move apart (diverge), or rift. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.

Rift valleys are created by tectonic activity and not the process of erosion.

Tectonic plates are huge, rocky slabs of Earth's lithosphere—its crust and upper mantle. Tectonic plates are constantly in motion—shifting against each other in fault zones, falling beneath one another in a process called subduction, crashing against one another at convergent plate boundaries, and tearing apart from each other at divergent plate boundaries.

The most well-known rift valley on Earth is probably the so-called "Great Rift Valley System" which stretches from the Middle East in the north to Mozambique in the south. The area is geologically active, and features volcanoes, hot springs, geysers, and frequent earthquakes.

Divergent boundary on land describes the boundary where earthquake activity occurs along rift valleys

for better understanding let's explain divergent plate boundary

Divergent plate boundary often happens only where 2 tectonic plates separate and thereafter create new land. most of them are in the ocean (Mid Atlantic Ridge). The Great Rift Valley in Africa is an example of a divergent plate boundary on thereafter the Great Rift Valley is filled of with water and product is a sea.Rift valley is commonly known as an area in a mid-ocean ridge where the plates are often separated and new crust begins to form. where plate tectonics exist, there is a divergent boundary or divergent plate boundary also called constructive boundary or

from the above we can therefore say that the answer Divergent boundary on land describes the boundary where earthquake activity occurs along rift valleys, is correct

If 23.6 grams of a substance reacts with 42.5 grams of another substance, what would we expect the mass of the products to be after the reaction?

Answers

Answer:

The correct answer is 66.1 g

Explanation:

According to Law of Conservation of the Mass, the mass of an isolated system is neither created or destroyed during chemical reactions. It is transformed. So, in a chemical reaction, the atoms of reactants are reoganizated by forming other compounds but the mass is conserved. Thus, the total mass of reactants is always equal to the total mass of products. If 23.6 g of a substance reacts with 42.5 g of another substance, the total mass of the products will be equal to the total mass of reactants:

23.6 g + 42.5 g = 66.1 g reactants = 66.1 g products

Find [H3O+], [OH-], & pOH for a window-cleaning solution whose pH is 4.33.

Answers

Answer:

[tex][H_3O^+] = 1*10^{-4.33} \ M[/tex][tex][OH^-] = 1*10^{-9.67} \ M[/tex][tex]pOH = 9.67[/tex]

Explanation:

Given;

pH of the solution = 4.33

H₃O+ is calculated as;

pH = -log[H₃O⁺]

4.33 = -log[H₃O⁺]

-4.33 = log[H₃O⁺]

10⁻⁴°³³ = [H₃O⁺]

[tex]Thus, [H_3O^+] = 1 *10^{-4.33}[/tex] M

[OH⁻] is calculated as;

[H₃O⁺] x [OH⁻] = 10⁻¹⁴

10⁻⁴°³³ x [OH⁻] = 10⁻¹⁴

[tex][OH^-] = \frac{10^{-14}}{10^{-4.33}} = 10^{-9.67}\\\\Thus, [OH^-] = 1*10^{-9.67} \ M[/tex]

pOH of the solution is calculated as;

pOH  +  pH = 14

pOH  + 4.33 = 14

pOH  = 14 - 4.33

pOH = 9.67

Thus, pOH of the solution is 9.67

Summary of the calculation:

[tex][H_3O^+] = 1*10^{-4.33} \ M[/tex][tex][OH^-] = 1*10^{-9.67} \ M[/tex][tex]pOH = 9.67[/tex]

Of these four liquids, which has the lowest viscosity? options: A. Pancake syrup at room temperature B. Motor oil that is in the refrigerator C.Liquid mercury at room temperature D. A glass of lemonade at room temperature

Answers

Answer: B. Motor oil that is in the refrigerator

Explanation:

Viscosity can be defined as the resistance provided by the fluid against its movement or flow. It restricts the resistance to change in shape or movement of fluid.  The water has high viscosity as the water molecules do not restrict movement on the surface.

According to the given problem, motor oil has lowest viscosity because it may contain heavy hydrocarbons, which may restrict its flow also when kept in refrigerator, the bonds between hydrocarbons get compact hence, viscosity decreases.

Answer:

Option C, .Liquid mercury at room temperature

Explanation:

The viscosity of liquid mercury at room temperature is 1.526 cP. While the visocsity of lemonade at room temperature ranges between 15.10 to 17.44 cP. Viscosity of Motor oil kept in the refrigerator is equal to 1328.0 cP. And Viscosity of Pancake syrup at room temperature  is 5,000 cp. Hence, out of all the four liquids, mercury has the lowest viscosity

In photosynthesis, what are the two major reactions that take place?

Answers

Answer:

The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.

Explanation:

Hope you get it right!

The two major reactions that takes place in photosynthesis are light dependent and light independent reactions.

PHOTOSYNTHESIS:

Photosynthesis is the process by which green plants and other autotrophic organisms obtain their own food using energy from sunlight.

The process of photosynthesis takes place in the chloroplast organelle of the cell where a pigment called CHLOROPHYLL, absorbs photons of light.

Photosynthesis, however, consists of two stages namely: light dependent and light independent reactions.

Light dependent reaction takes place strictly in the presence of sunlight and involves the production of ATP and NADPH molecules, which are used in light independent reaction.

Light independent reaction, also called Calvin cycle, can occur with or without sunlight, hence, it is called dark reaction. Calvin cycle uses the product of the light stage to synthesize glucose molecule.

Therefore, the two major reactions that takes place in photosynthesis are light dependent and light independent reactions.

Answer:

4,387.5 J was absorbed

Explanation:

Calorimetry is the part of physics that is responsible for measuring the amount of heat generated or lost in certain physical or chemical processes.

In this way, there is a direct proportional relationship between heat and temperature. Thus, the amount of heat received or transferred by a body when it undergoes a temperature variation (Δt) without there being a change of physical state (solid, liquid or gaseous) is calculated using the following expression:

Q = c * m * ΔT

Where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case:

Q= ?c= 0.900 [tex]\frac{J}{g*C}[/tex]m= 15 gΔT=Tfinal - Tinicial= 350 °C - 25 °C= 325 °C

The Ka for benzoic acid is 6.5 × 10−5. Calculate the pH of a 0.12 M benzoic acid solution.

Answers

Answer:

pH=4.05

Explanation:

C7H6O2  -> C7H6O-  + H+

ka= [C7H6O-] [H+]/[C7H6O2]

During equilibrium

[C7H6O-]= [H+]= x^2

[C7H6O2]=0.12-x

Replace

ka= x^2/0.12-x

6.5 x10^-5= x^2/0.12-x

7.8x10^-6 - 6.5 x10^-5x=x^2

x^2+ 6.5 x10^-5x - 7.8x10^-6

Solution of quadratic equation

x=8.8 x10^-5

pH= -log [H+]= -log 8.8 x10^-5=4.05

The pH value of the benzoic acid solution is equal to 4.05.

What is pH?

pH can be defined the negative logarithm of hydrogen ion concentration. pH can be seen as an abbreviation of the power of hydrogen or the concentration of hydrogen ions in a solution.

Mathematically, pH equals the negative logarithmic value of the concentration of hydrogen ion (H⁺).

pH = -log [H⁺]

The pH scale have range from 0 to 14 when 7.0 is neutral. A low pH is acidic and a high pH is basic. Pure water has a pH of 7.0.

The partial dissociation of benzoic acid in an aqueous solution can be shown as:

[tex]C_6H_5COOH +H_2O[/tex]  ⇄  [tex]C_6H_5COO^- +H_3O^+[/tex]

ka= [C₆H₅O⁻] [H₃O⁺]/[C₆H₅COOH]

At equlibrium:[C₆H₅O⁻] = [H₃O⁺] = x²

[C₆H₅COOH] = 0.12-x

The equilibrium constant: ka= x²/0.12-x

6.5 × 10⁻⁵ = x²/0.12-x

7.8 × 10⁻⁶- 6.5  × 10⁻⁵ x = x²

x²+  6.5  × 10⁻⁵ x- 7.8 × 10⁻⁶ = 0

The solution of the given quadratic equation will be:

x = 8.8 × 10⁻⁵

pH= -log [H⁺]= -log [8.8 × 10⁻⁵] =  4.05

Therefore, the pH of the given benzoic acid solution is 4.05.

Flashes of light burst through the darkness, and wind races past my window. The thrilling combination of sight and sound conjures up visions of dragons roaring proudly, breathing fire, and soaring across the midnight sky. Dragons first fascinated me when I was a little girl. They have followed me ever since. The magnificent creatures appeared in storybooks I read in the library, paintings I saw in museums, movies I watched in the theater, and the dreams I had in my sleep. By the time I was thirteen, one question consumed me. I wanted to know if dragons ever existed, so I set out on a quest for facts.2As I started my research, I discovered many skeptics. Scientists presented evidence to show why dragons could notand did notexist. They explained that it would be impossible for dragons to fly because they would be too big. They laughed at the idea of dragons breathing fire. They pointed out that no other animal has ever done this. They said that if dragons had lived, someone would have found remains somewhere in the world. No bones about it, there were plenty of logical explanations. It would have been easy for me to accept that the only place dragons ever existed was in the imaginations of those who believed.3I could have given up, but I thought about my grandmother. She always told me that "people who believe that science is the answer to everything are missing out on everything else." With her words in mind, I searched some more. There were many facts that hinted that dragons may not be fictional. I noticed that cultures across the world all described dragons in similar ways. This was odd because they had no way to communicate with each other. I found dragons mentioned in more than just stories. They appeared in old legal papers, in the travel logs of Marco Polo, and in the Bible. I saw that the Chinese calendar uses a different animal each year. Dragons are included along with eleven real animals. I began to believe it was a real possibility that all of these people were talking about a creature that actually existed. 4With renewed hope that there was some truth to the legends, I looked for new research. I found that some experts disagreed with popular arguments against dragons. They suggested that a dragon could have four stomachs like a cow. If it created stomach gases like birds, it might create enough to lift itself off the ground. This would give it the ability to fly. If it forced out air when diving toward the earth, it might release gases which could ignite into flame. When the animal died, the stomachs would release strong acids that would dissolve its dead body over time. Biologists backed up these ideas with sketches and models based on known animals. Not everyone agreed with these ideas, but many of the things we accept about dinosaurs and other extinct species started the same way.5I doubt we will ever truly know whether dragons existed. There may always be two sides to the fiery debate. Some will say the stories come from active imaginations. Some will believe with all their hearts that the legendary creatures roamed our ancient world. I don't know for certain which side to believe, but the sound and fury of a night like this makes me smile. It rekindles my childhood dreams and keeps the exciting possibility alive.Which best states the main idea of the text? I have found no proof that dragons ever existed.
