Answer:

Simple and facilitated diffusion are both similar types of phenomenon where the substances are moved from a region of high concentration to lower concentration across a semi-permeable membrane.

The main difference between them is that the facilitated diffusion requires a special type of protein or carrier molecules in order to transport the substances whereas simple diffusion does not require such molecules. The rate of flow of these substances is high in the facilitated diffusion in comparison to the simple diffusion.

Number of Mg(OH)2 formula units in 7.40 moles of Mg(OH)2.

-Dominant- [34]

The answer is 4.45 × 10²⁴ units.

To calculate this, we will use Avogadro's number which is the number of units (atoms, molecules) in 1 mole of substance:
6.02 × 10²³ units per 1 mole

So, we need a proportion:
If 6.02 × 10²³ units are in 1 mole, how many units will be in 7.40 moles:
6.02 × 10²³ units : 1 mole = x : 7.40 moles

After crossing the products:
1 mole * x = 7.40 moles * 6.02 × 10²³ units
x = 7.40 * 6.02 × 10²³ units
x = 44.5 × 10²³ units = 4.45× 10²⁴ unit

low level waste

Explanation:

Low level wastes are nuclear wastes generated from hospitals and industries as well as the nuclear fuel cycle, and is comprised of paper, rags, tools, clothing, filters, etc., which contain small amounts of mostly short-lived radioactivity.

Low level wastes are typically radioactive in nature and are difficult to dispose.
They originate from radioactive processes in the hospital and nuclear reactors.
There has been growing concerns about the safe disposal of radioactive wastes over the years.
