What cause the slight positive (8+) and negative (8-) poles on a molecule of H20?

Biology
1 answer:
taurus [48]3 years ago
7 0

Answer:

In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms

Because of the water molecule's bent shape and its atoms' unequal sharing of electrons, it has partial positive (δ+) and partial negative (δ-) poles. ... A hydrogen bond occurs when molecules that have hydrogen covalently bonded to oxygen, nitrogen or fluorine interact.

When injected, benzedrine, dexedrine, and methamphetamine increase the release of serotonin, norepinephrine, and ______________
const2013 [10]
When injected, benzedrine, dexedrine, and methamphetamine increase the release of serotonin, norepinephrine, and dopamine in the brain. Benzedrine, dexedrine, and methamphetamine are examples of amphetamines. They are stimulants, which speed up the messages travelling between the brain and the body. They may be used to treat attention deficit hyperactivity disorder.

Energy used by the body to perform muscular contractions is called adenosine diphosphate, or ADP.
Bezzdna [24]

Answer:

The energy used for muscular cont ration is ATP(adenosine triphosphate) This is the energy currency produced in the mitochondrial during cellular respiration.

During muscles contraction.The ATPs is broken down to ADP and Pi.

This is the breakdown of energy rich bonds binding phosphate ions with ATP.The breakdown of the bonds produced -32kJper the 3 bonds in ATP. Therefore as each bond is broken, energy is produced for muscle contraction

It is an exergonic reaction with production of heat.

Thus ATP is used for muscle contraction.ADP is the intermediate of ATP when one Phosphate is removed during the breakdown.

Thus the sequence is Adenosine triphosphate (3 phosphate) to Adenosine diphosphate(2 phosphate) to Adenosine monophosphate (1 phosphate)

Each bond breakin gives equal energy of -32kJpermol.

DIA [1.3K]

Answer:

Explanation:

It depends on the geography of your environment. I'd recommend using Solar Panels in a hot area, or Windmills/Wind energy in an area with lots of wind. There are other options too, like water/tidal energy for a place in the Caribbean or surrounded by lots of water. Pick one of those.
