The three main cycles of an ecosystem are the water cycle, the carbon cycle and the nitrogen cycle. These three cycles working in balance are responsible for carrying away waste materials and replenishing the ecosystem with the nutrients necessary to sustain life.
Explanation:
cycles such as the water cycle keep the earth hydrated by feeding rain to trees, plants, etc.
write out the products that would be created during this neutralization reaction H2SO4 + Cu(OH)2
Answer:
H2SO4+CU(OH)2 = CUSO4+2H2O
The general neutralization reaction between an acid and a base takes the form: acid + base → salt + water.
If you have some acid HA neutralizing some base BOH, the salt would be an ionic compound composed of the conjugate acid of BOH (i.e., B⁺) and the conjugate base of HA (i.e., A⁻).
Applied here, H2SO4 and Cu(OH)2 would react to form a salt CuSO4 (the Cu²⁺ ions coming from the copper(II) hydroxide and the SO4²⁻ ions coming from the sulfuric acid) and H2O.
Thus, the products of this neutralization reaction would be copper(II) sulfate (CuSO₄) and water (H₂O).
The balanced equation for this reaction would accordingly be:
H₂SO₄ + Cu(OH)₂ → CuSO₄ + 2H₂O.

Answer:
c
Explanation:
because the sun is at the center of the universe the planet orbit the sun its basically a simple answer so if you need more help im right here
The sun and the planets are part of the solar system. The sun is in the center of the system, and the planets revolve around it. Thus, option C is correct.
What is the solar system?A solar system is a part of the Milky Way galaxy that includes the planets, stars, sun, moon, asteroids, etc. The Sun is the star that is fixed at the center of the system.
The planets are not fixed and revolve in orbit around the sun and rotate on their axis. The sun and planets are made up of gases and have different atmospheres.
Therefore, option C. sun is at the center around which the planets revolve.
