Answer:
ecosystem:a biological community of interacting organisms and their physical environment.
rainforest: a luxuriant, dense forest rich in biodiversity, found typically in tropical areas with consistently heavy rainfall.
major part of rain forest:Most rainforests are structured in four layers: emergent, canopy, understory, and forest floor. Each layer has unique characteristics based on differing levels of water, sunlight, and air circulation.
coral reefs :a ridge of rock in the sea formed by the growth and deposit of coral.
type of coral reefs:fringing reefs, barrier reefs, atolls, and patch reefs

Answer:
The pH of the resulting solution is 9.02.
Explanation:
The initial pH of the buffer solution can be found using the Henderson-Hasselbalch equation:
![pOH = pKb + log(\frac{[NH_{4}Cl]}{[NH_{3}]})](https://tex.z-dn.net/?f=%20pOH%20%3D%20pKb%20%2B%20log%28%5Cfrac%7B%5BNH_%7B4%7DCl%5D%7D%7B%5BNH_%7B3%7D%5D%7D%29%20)
Now, the perchloric acid added will react with ammonia:
Also, the moles of ammonium chloride will increase in the same quantity according to the following reaction:
NH₃ + H₃O⁺ ⇄ NH₄⁺ + H₂O
Finally, we can calculate the pH of the resulting solution:
Therefore, the pH of the resulting solution is 9.02.
