Transport of Na+ from a place of low concentration to a place of higher concentration. <u>This is the right answer.</u>

<u />

The sodium-potassium pump is the most common and well-known example of active transport. At the cell membrane, the sodium-potassium pump moves 3 sodium ions out of the cell and two potassium ions into the cell per ATP. Examples of active transport include the uptake of glucose in the human intestine and the uptake of minerals and ions into the root hair cells of plants.

One of the greatest examples of active transport is the movement of calcium ions out of cardiomyocytes. Cells secrete proteins such as enzymes, antibodies, and various other peptide hormones. Amino acids are transported across the intestinal mucosa of the human intestine. The movement of ions or molecules across cell membranes to regions of a higher concentration is assisted by enzymes and requires energy.

1. Which of the following statements is a consequence of the equation E=MC2
finlep [7]

Answer:

D. All of the above​

Explanation:

E = MC² is a common equation in physics.

E is energy

M is mass

C is the speed of light

The law was stated by Albert Einstein.

  • From this law, it was shown that energy is released when matter is destroyed.
  • Mass and energy are equivalent as seen in nuclear reactions where mass is converted to energy.
  • Mass and energy is usually conserved in any process and this is a subtle modification of the law of conservation of matter and energy.
  • Most of these postulates apply to nuclear reactions which generally do not follow some precepts of chemical laws.

The ksp of pbi2 is 1.4 x 10-8. what is the molar solubility of lead(ii iodide in a solution of 0.400 m sodium iodide?
tino4ka555 [31]
The solubility product of a substance us calculated by the product of the concentration of the dissociated ions in the solution raise to the stoichiometric coefficient of the ions. Therefore, we need the dissociation reaction. For this, it will have the reaction:

PbI2 = Pb^2+ + 2I-

We solve as follows:

Ksp = [Pb2+][I-]^2 = <span>1.4 x 10-8
</span><span>1.4 x 10-8 = x(2x)^2
</span><span>1.4 x 10-8 = 4x^3
x = 1.5x10^-3 M

The molar solubility would be </span>1.5x10^-3 M.

What is the mass in grams of a pure iron cube that has a volume of 4.60 cm3
yuradex [85]
In order to determine the mass of a substance given the volume, we require the density. The density of iron is 7.87 grams/cm³

Now,

Density = mass / volume

Mass = density * volume

Mass = 7.87 * 4.6

36.2 grams of iron are present in the cube
