Explanation:
Hydrogen selenide (H2Se) reacts with water according to the following equation. H2Se H2O → SeH– H3O In three to five sentences, identify the acid, base, conjugate acid, and conjugate base in this reaction. Use patterns in the periodic table to explain why the substances you identified acted as the acid and the base in this reaction.
Taking into account the Brønsted-Lowry acid-base theory:
H₂Se behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.H₃O⁺ is the conjugate acid of the H₂O and SeH⁻ is conjugate base of H₂Se.
The Brønsted-Lowry acid-base theory (or the Brønsted-Lowry theory) identifies acids and bases based on whether the species accepts or donates protons or H⁺.
According to this theory, acids are proton donors while bases are proton acceptors. That is, an acid is a species that donates an H⁺ proton while a base is a chemical species that accepts an H⁺ proton from the acid.
So, reactions between acids and bases are H⁺ proton transfer reactions, causing the acid to form its conjugate base and the base to form its conjugated acid by exchanging a proton.
In other words, a conjugate base is an ion or molecule resulting from the acid that loses the proton, while a conjugate acid is an ion or molecule resulting from the base that gains the proton:
acid + base ⇄ conjugate base + conjugate acid
In this case, you know:
H₂Se + H₂O → SeH⁻ + H₃O⁺
H₂Se behaves like acid because donates an H⁺ proton while H₂O behaves like base because accepts an H⁺ proton from the acid.
So, H₃O⁺ is the conjugate acid of the H₂O and SeH⁻ is conjugate base of H₂Se.

Laying down of sediment in layers carried by wind, water or ice is the best definition of deposition in geology. Thus option C is correct.
What is geology?The main branch of Earth science, geology, studies how the earth was created, as well as its makeup and the processes that impact it. Natural humanity's field of geology is interested with Earth and other celestial objects, the structures or rocks that make them up, and also the mechanisms that cause these shifts over time.
A deposition is the act of depositing sediment that has been carried by the air, water, seas, or ice. Granules, sand, clay, and salts that have been dissolved in the water can all be used to convey sediment.
Salts could later be accumulated through evaporation or organic action. Traditionally, sedimentary rocks are found in strata known as strata. Younger layers sit on top of older levels in unbroken strata. Therefore, option C is the correct option.

Answer:
They are cooler and drier than tropical rain forests. Abiotic factors, or nonliving factors, of a temperate rain forest include temperature, water, cloud cover, soil and light. These abiotic factors interact with biotic, or living factors, to form the rain forest's unique ecosystem.
The fundamental differences between rainforests in tropical and temperate regions of the world are largely due to abiotic elements such as climate, soil type, precipitation, temperature, and sunlight.
What abiotic characteristics of the rainforest biome?Abiotic influences in the rainforest include things like precipitation, sunlight, temperature, and other such things, whereas biotic factors include specifically living things, such as plants and animals.
Animals, birds, insects, plants, trees, and other biotic variables are only a few examples. Plants are eaten by insects, which are then consumed by animals and birds. Larger creatures than consume smaller animals. Water, nutrients in the soil, and temperature are examples of abiotic variables.

How do the passages' themes compare? Both passages have the theme "time erases everything." "Elgin Marbles" has the theme "art outlasts even death," while "Ozymandias" has the theme "death comes to everything." Both passages have the theme "nature is cruel." "Elgin Marbles" has the theme "decay is inevitable," while "Ozymandias" has the theme "fame survives death."
The two passages have the theme "time erases everything," as shown in the first answer option.
We can arrive at this answer because:
The passage from the poem "Ozymandias," shows how all the glory, wealth, and magnificence of a great leader fades over time.In this poem, we can see that someone seen as the king of kings, can have all his power terminated and buried in the sand.In "On Seeing the Elgin Marbles," we can see how memorable moments pass and become memories of "the old days," even though it seems like it will last forever.In this case, we can see that the two poems reinforce the idea that everything is fleeting, and that time brings the end of all things.

In basketball, hang time is the time that both of your feet are off the ground during a jump. The equation for hang time is t = 2 (StartFraction 2 h Over 32 EndFraction) Superscript one-half , where t is the time in seconds, and h is the height of the jump, in feet. Player 1 had a hang time of 0.9 s. Player 2 had a hang time of 0.8 s. To the nearest inch, how much higher did Player 1 jump than Player 2? in.
Answer:
8in
Explanation:
edge 2020
The amount of height that player 1 jumped higher than player 2 to the nearest inch is; 8 inches
How to substitute values into an equationWe are given the hang time equation as;
t = 2(2h/32)^(½)
Where;
h is height of jump
Hang time of player 1 = 0.9 s
Hang time of player 2 = 0.8 s
Let's make h the subject of the hang time equation to get;
h = 2t²
For player 1;
h1 = 2(0.9)²
h1 = 3.24 ft
Converting to inches gives;
h1 = 38.88 inches
For player 2;
h2 = 2(0.8)²
h2 = 2.55 ft
Converting to inches gives
h2 = 30.72 inches
Difference in jump height = h1 - h2
Difference in jump height = 38.88 - 30.72
Difference in jump height ≈ 8 inches
