Explanation:
One of the most fascinating chemical experiments is the reaction between silver nitrate and copper wire in water. Characterised by fractal-like precipitates, this experiment is a stunning example of a simple redox reaction.
When elements are heated/energized their electrons then absorb the energy and transition into a higher energy level known as the excited state. Then electrons then eventually fall back to their lowest state of energy or their ground state.
hope this helps :)p
"People should remove native plants around watersheds" option should a person avoid doing in order to better protect the quality of watersheds.
<u>Option: A</u>
<u>Explanation:</u>
Watershed is basically a source of large amount of water like river, sea, etc to another location like lake, ponds and stream.This is seen majorly during rainy season by water harvesting to supply further for farming, portable water plant, manufacturing sectors, enrich habitat to number of plants and animals, etc. Waterways face issues when erosion, pollutants and runoff of animal waste take place, which act as barrier for water flow, as it decreases the quality which affect aquatic animals life, reduce oxygen content. Native plants near watersheds is also a habitat for many animals and species thus it should not be removed until some major flaw occurs.
Answer:
Explanation:
ratio of moles of N and O in molecule =
N / O = 2.17 / 4.35
1/2
empirical formula = NO₂
