Answer: Option D

Explanation:

Chemotrophs can be defined as the organism which has the ability to get energy by the oxidation of electron donors present in the nearby environments.

These molecules in the environment can be organic or inorganic.These bacteria are usually called as thiobacillus denitrificans.

These bacteria reduce the nitrate into nitrite and the energy source for these bacteria is thiosulfate(sulfur).

Explanation:

A and D

A. A pressure equal to that of the osmotic pressure will result in reverse osmosis.

D. The movement of the solvent particles from the concentrated solution to the dilute solution is known as reverse osmosis.

During osmosis, water molecules from the less concentrated right side, will flow into the left side til they equilibrate- at equilibrium both sides will have the same concentration of solute.

Thus, the water passes through the membrane due to the difference in osmotic pressure/ solute concentration on either side of the membrane, this means that the water moves from regions of high osmotic pressure/concentration to regions of low osmotic pressure /concentration.  

Water potential equal to the pressure potential shifts  the equilibrium, resulting in the movement of solute.

<h3>                              φ= φs+φp</h3>

However, in reverse osmosis, solute molecules move from regions of high solute concentration, to regions of low solute concentration across the membrane.

A sample of gas has a volume of 12.0 L and a pressure of 1.97 atm. If the pressure is increased to 3.40 atm, what is the new vol
sveticcg [70]
As far as I know, may be wrong :When pressure is multiplied by a number, the gas volume also gets multiplied by the same number. So, the answer can be found by doing: (3.4/1.97)(12), and the answer is about 20.71.

“Red sky at night, sailors delight. Red sky in morning, sailors take warning.”
A reddish sunset means that the air is dusty and dry. Since weather in North American latitudes usually moves from west to east, a red sky at sunset means dry weather—good for sailing—is moving east. Conversely, a reddish sunrise means that dry air from the west has already passed over us on their way easy, clearing the way for a storm to move in.

“Clear Moon, frost soon.”
When the night sky is clear, Earth’s surface cools rapidly—there is no cloud cover to keep the heat in. If the night is clear enough to see the Moon and the temperature drops enough, frost will form. Expect a chilly morning!




“Ring around the moon? Rain real soon.”
A ring around the moon usually indicates an advancing warm front, which means precipitation. Under those conditions, high, thin clouds get lower and thicker as they pass over the moon. Ice crystals are reflected by the moon’s light, causing a halo to appear.




“Rain foretold, long last. Short notice, soon will pass.”
If you find yourself toting an umbrella around for days “just in case,” rain will stick around for several hours when it finally comes. The gray overcast dominating the horizon means a large area is affected. Conversely, if you get caught in a surprise shower, it’s likely to be short-lived.



“The higher the clouds, the finer the weather.”
If you spot wispy, thin clouds up where jet airplanes fly, expect a spell of pleasant weather.

Keep an eye, however, on the smaller puff clouds (cumulus), especially if it’s in the morning or early afternoon. If the rounded tops of these clouds, which have flat bases, grow higher than the one cloud’s width, then there’s a chance of a thunderstorm forming.

BRAINIEST!! how do i balance As+H2=AsH3 step by step will give brainiest only to people who do step by step
gladu [14]

Answer:

1. As+H2=AsH3

2. draw a line under the problem with this:

A = 1            | A = 1

H = 2           | H = 3

3. We need everything to be equal (2x3 to get 6 then count the As on the product side to get the 2, then add 2 A on the reactant side):  

A = 2            | A = 2

H = 6           | H = 6

4. 2As + 3H2 = 2AsH3

hope this helps
