Answer:
the first line
Explanation:
A rarefaction is a region in a longitudinal wave where the particles are furthest apart. ... The region where the medium is compressed is known as a compression and the region where the medium is spread out is known as a rarefaction.
use this picture as a reference:
1. 1 2 1 2
2. 2 1 1 1
3. 2 2 2 1
4. 1 2 1 2
5. 2 3 2 3
The answer would be Meiosis
Answer: exothermic
Explanation: chemical reactions that release energy is called exothermic, and in this case, more energy is being released. (I THINK)
Answer:
Partia pressure N₂ → 0.975 atm
Explanation:
Let's analyse the moles fractions:
N₂ → 0.25
O₂ → 0.65
He → 0.1
Partial pressure / Total pressure = Mole fraction
Partial pressure N₂ / 3.9 atm = Mole fraction N₂
Partial pressure N₂ / 3.9 atm = 0.25
Partial pressure N₂ = 3.9 atm . 0.25 → 0.975 atm
