Answer:
i think the answer is the last one.
The water molecules move by active transport into the cell from high water concentration to low water concentration.
Explanation:
Granite is an igneous type of rock.
The balanced chemical reaction is written as:
<span>2Al2O3 = 4Al + 3O2
We are given the amount of aluminum oxide used in the reaction. This will be the starting point for the calculations. We do as follows:
26.5 mol Al2O3 ( 3 mol O2 / 2 mol Al2O3 ) = 39.75 mol O2 produced</span>
Answer:
B) Ksp = 3.7 E-11
Explanation:
CaF2 ↔ Ca2+ + 2F-
S S 2S,,,,,,,,,,,,,,,in the equilibrium
⇒ Ksp = [ Ca2+ ] * [ F- ]²
⇒ Ksp = S * ( 2S )²
⇒ Ksp = 4S³
⇒ Ksp = 4 * ( 0.00021 )³
⇒ Ksp = 4 * 9.261 E-12
⇒ Ksp = 3.704 E-11
