Answer:
b) a stickleback's aggressive behavior
Explanation:
Sticklebacks are small carnivores that live off of small animals and larvae. An adapted behaviour would be changes in their attitudes and behaviours as compared to the characteristics are given to them by the Creator.
For example lions nature is to hunt, spiders nature is to build nests whereas birds nature is to build nests. But being aggressive is not one of Sticklebacks natural instincts. This is something they have adapted with time due to external factors.
Moles of CaBr2 = 5/molar mass of CaBr2
= 5/199.886
= 0.025 moles.
Hope this helps!
Data Given:
Initial Volume = V₁ = 36.7 L
Initial Pressure = P₁ = 145 kPa
Initial Temperature = T₁ = 65 °C + 273 = 338 K
Final Volume = V₂ = ?
Final Pressure = P₂ = 101.325 kPa (Standard Pressure)
Final Temperature = T₂ = 273 K (Standard Temperature)
Formula used:
As number of moles are constant, so Ideal Gas equation in following form is used,
P₁ V₁ / T₁ = P₂ V₂ / T₂
Solving for V₂,
V₂ = P₁ V₁ T₂ / T₁ P₂
Putting Values,
V₂ = (145 kPa × 36.7 L × 338 K) ÷ (273 K × 101.325 kPa)
V₂ = 1798667 ÷ 27661.25
V₂ = 65.02 L
Balancing the equation, we get:
2C₂H₆O + O₂ → 2C₂H₄O₂ + 2H₂O
So
α = 2
β = 1
γ = 2
δ = 2
To move around more. bounce off walls ect. they are more energised
