Answer:
Explanation:
The mountain ecosystems are characterized by coniferous tree species such as pinus, firs, and spruces and species such as deers, bears, and wolves.
A beetle that kills coniferous trees would be a greater threat to the ecosystem than a wolf that hunts and eat deer because the dominant trees in the ecosystem are conifers. Hence, <u>a beetle that kills coniferous trees might end up killing the dominant tree species in the ecosystem and this will gravely affect other plant and animal species within the ecosystem. </u>
<em>Wolves and deers have their niche in the mountain ecosystem already and hence, their populations are naturally limited by limiting factors of the environment. Hence, a wolf that hunts and eats deers would be of a lesser threat to the mountain ecosystem.</em>
Basically, the arrangement of electrons in electronic configuration follows three principles:
1. Aufbau Principle
You start from the highest energy level to the lowest. The arrangement is: <span>1s<2s<2p<3s<3p<4s<3d<4p<5s<4d<5p<6s<4f<5d<6p<7s<5f<6d<7p.
2. Hund's Rule
Each box in the configuration can hold up to 2 electrons. This rule tells you to fill all boxes of one particular subshell with 1 electron first, before double occupying them.
3. Pauli's Exclusion Principle
This rule tells you that the two electrons in a box shall always have opposite spins, represented by one half-arrow up and one half-arrow down.</span>

I think A. o2 is oxygen, h202 is a clear liquid like bleach, And H20 is water lol :P
Answer:
W = ΔKE = 1/2mv₂⁽²⁾ - 1/2mv₁⁽²⁾
Explanation:
Work means Change In Kinetic Energy.
Kinetic-Energy is equal to change in velocity multiplied by mass and divided by 2
∴ KE = 1/2m²
Change in Kinetic-Energy =KE₂ - KE₁
=1/2mv₂⁽²⁾ - 1/2mv₁⁽²⁾
