Answer:
D.) The acceleration due to gravity of 9.8 m/s/s is supported
Explanation:
Answer:
See the steps below (8,681.25 g of will be needed0
Explanation:
From the equation, 4 moles of H2 requires 1 mole of Fe3O4.
1st step: calculate the number of mole of 300 g of H2.
mole = mass/molar mass
Mole of 300 g H2 = 300/2 = 150 mole
Hence, 150 moles of H2 will require: 150/4 = 37.5 moles of Fe3O4.
Step 2: Use the mole of Fe3O4 to calculate the mass of Fe3O4
mass = mole x molar mass
mass of 37.5 mole Fe3O4 = 37.5 x 231.5 = 8,681.25 g
Hence, 8,681.25 g of Fe3O4 will be required to completely react with 300 g H2
As the ion channel opens and allows its movement in an energetical direction. Then it redistributes these ions in opposite direction back across the membrane.
The Na channel opens as the membrane is hyperpolarized. The averaged collective response of single channels resembles the time course of the macroscopic current. Macroscopic currents are blocked by Tetrodotoxin (TTX) but not microscopic currents.
Opening and closing of Na channels are concentration dependent. The function of ion channels inorganic ions (like Na, K, Ca or Cl) to rapidly diffuse their electrochemical gradients that is across the lipid bilayer.
