Answer:
True
Explanation:
The El Nino/Southern Oscillation occurs in between the three phases Neutral, La Nina or El Nino.
The humboldt current takes cold water to South America's west coast to the tropics from the Southern Ocean. Because of the welling which takes place in Peru this process is enhanced. Due to the trade winds near the equator the cold water travels west where it heats up due to the sun. This makes the water of the western Pacific warmer.
Answer:
the maximum energy available for pumping a mole of glucose into the cell = 3190J
Explanation:
The detailed steps and appropriate derivation from the Vant hoff Isotherm equation is as shown in the attachment.
To find the freezing point, you use the following formula
fp solution= fp solvent - Δfp solution
fp solvent= 0 C (since the solvent was not stated, you can assume is water which freezing point is 0 degree celsius)
but first, we need to find the depression in freezing point (Δfp solution)
Δfp solution= Kf x i x m, where Kf is constant for the solvent, i is the number of particles produced by the solute and m is the molality of the solution.
Kf= 1.86 for water
i= 4 , becausethe solute breaks into 4 ions, K3PO4---> 3K+ + PO4-3
m= 2.60
Δfp solution= (1.86) (4) (2.60)= 19.3 C
fp solution= 0 - 19.3C=<span> -19.3C

for boiling point, we use a similar formula and way to solve it.
Δbp solution= bp solvent + Δbp solution
bp solvent= 100 C for water
to find the elevation boiling point (Δbp soln) is equal to:
Δbp solution= Kb x i x m
Kb= 0.512
i= 4
m= 2.60
Δbp solution= (0.512) (4) (2.60)= 5.32 C
bp solution= 100C + 5.32C= <span>105.32 C</span>
