Answer:
These clouds extend through the lower and mid-layers of the troposphere bringing rain to the surface below.
Explanation:
The bases of clouds in the middle level of the troposphere, given the prefix “alto,”
Answer:
Option a . 0.154L
Explanation:
P₁ . V₁ = P₂ . V₂
when we have constant temperature and constant moles for a certain gas.
At sea level, pressure is 1 atm so:
0.5 L . 1atm = V₂ . 3.25 atm
(0.5L . 1atm) / 3.25 atm = 0.154 L
Answer:
The two-step mechanism is a slow mechanism and a fast mechanism. When we combine them, the result is
2H₂O₂ (aq) ⇒2H₂O (l) + O₂ (g)
Explanation:
We know that the decomposition of hydrogen peroxide is catalyzed by iodide ion, which means that the iodide ion will react with the hydrogen peroxide. There is a slow mechanism and a fast one:
H₂O₂(aq) + I₋(aq) ⇒ H₂O(l) + IO₋(aq) this is the slow reaction
IO₋(aq) + H₂O₂(aq)⇒ H₂O(l) + O₂(g) + I₋ (aq) this is the fast reaction
If we cancel the same type of molecules and ions, the final result is:
2H₂O₂ (aq) ⇒2H₂O (l) + O₂ (g)
