Answer:

Clean energy are renewable energy. This are energy from natural sources that are renewed without extra cost. Sun, wind, water are examples of renewable natural resources that helps generate clean energy.

The energy are refer to as clean because, they do not lead to any deposit of gasses that can affect the environment leading to environmental pollution. They have little or no side effects, no combustions or release of gases that are toxic or can deplete the environment as in the case of non- renewable energy.

KengaRu [80]

Answer:

C.) 26 - 13

Explanation:

During mitosis, DNA is replicated during the S phase so that when the cell divides the daughter cells will have the same number of chromosomes that the parent cell had.

DNA replication also occurs during meiosis, but the cell divides twice, so the daughter cells will have half the number of chromosomes that the parent cell had. This is because the daughter cells are sex cells, which combine with another sex cell (either an egg or a sperm) to form one cell with a combined chromosome number.

A solution of acetic acid is prepared in water by adding 11.1 g of sodium acetate to a volumetric flask and brining in the volum

velikii [3]

Answer:

The concentration of

the Acetic Acid is 0.0325M

the Sodium Acetate is 0.1028M

Explanation:

Given

The dissociation of acetic acid is

CH3COOH + CH3COO- + H+ + HA -> A- + H+

We calculate the molarity of sodium acetate by using

Molarity = Moles/Volume

The formula weight of sodium acetate is 82.03 g/mol.

Moles = 11.1g/82.03g/mol

= 0.1353M

Since the volume is 1L, the molarity of sodium acetate will still be 0.1353M

The starting concentration of sodium acetate is 0.1353M

The final concentration of sodium acetate is the starting amount of sodium acetate, minus the amount that was protonated.

Assume that, x = concentration of acetic acid, which is the amount of sodium acetate that was protonated.

From the Henderson-Hasselbalch equation

PH = pKa + log[A-]/[HA]

[A-] = 0.1353 - x

[HA] = x

pKa = 4.75

PH = 5.25

Substitute in these values

5.25 = 4.75 + log(0.1353-x)/x

log(0.1353 - x)/x = 5.25 - 4.75

log(0.1353-x)/x = 0.5

log(0.1353 - x)/x = ½

(0.1353-x)/x = 10^½

(0.1353 - x)/x = 3.1623

0.1353 - x = 3.1623x

0.1353 = x + 3.1623x

0.1353 = 4.1623x

x = 0.1353/4.1623

x = 0.0325M

Therefore [HA] = x = 0.0325M

[A-] = 0.1353 - x = 0.1353 - 0.0325 =

[A-] = 0.1028M

The mesentery attached to the inferior margin of the stomach is called the ________.

vovangra [49]

The answer is greater omentum. The omentum is a membranous twofold layer of greasy tissue that spreads and backings the digestion tracts and organs in the lower stomach zone. The omentum is comprised of the more prominent omentum which is a vital stockpiling for fat stores and the lesser omentum which associate the stomach and digestion tracts to the liver.

<h2>Visceral pleura</h2>

Explanation:

The portion of the serous membrane that covers and adheres to the lung is called visceral pleura

Pleura are the pair of membranous linings surrounding the lungs
The visceral pleura covers each lung surface, and the parietal pleura covers the inner surface of the thoracic cavity
The visceral pleura is a delicate membrane which dips into the fissures between the lobes of the lung
Pleura allows the lungs to move inside the body cavity without friction as friction would cause damage to the lungs and the tissue in the chest wall
