Answer:The biosphere is all life on our planet. ... The impact on climate is mainly due to the connection between the biosphere and the atmosphere. Processes such as photosynthesis and respiration naturally affect the concentrations of gases such as oxygen and carbon dioxide in the atmosphere.
Explanation:
quá trình oxi hóa: Mg0 -> Mg2+ + 2e-
quá trình khử: 2H+ + 2e- -> H2 (cần 2 H+ để tạo 1 H2)
----> chỉ cần thêm 2 vào trước HCl (vì H+ là do HCl cung cấp)
----> Mg + 2HCl -> MgCl2 + H2
yay :)
An example of an external stimulus is a decrease in oxygen levels in the blood during exercise.

Explanation:
Free energy of mixing = ΔGmix = Gf - Gi
attached below is the required derivation of the
<u>a) Molar Gibbs energy of mixing</u>
ΔGmix = Gf - Gi
hence : ΔGmix = ∩RT ( X1 In X1 + X2 In X2 + X3 In X3 + ------- )
<u>b) molar excess Gibbs energy of mixing</u>
Ni = chemical potential of gas
fi = Fugacity
N°i = Chemical potential of gas when Fugacity = 1
ΔG = RT In ( a2 / a1 )
The word elliptical refers to an Oval.
