Why does the oxygen atom in a water molecule have a negative charge?

Biology
2 answers:
sergejj [24]3 years ago

Answer:

B

Explanation:

Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds. Consequently the electrons in the water molecule spend slightly more time around the oxygen atomic center and less time around the hydrogen atomic centers. The covalent bonds are therefore polar, and the oxygen atoms have a slight negative charge

Do you see a connection between wavelength and frequency? Explain.
katrin2010 [14]

Answer:

Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

Amplitude is the height of a wave which is the brightness of a light or loudness of a sound. So Frequency and Amplitude though are part of a wave are not dependent on each other. Their is no relation between frequency and amplitude.

Pavel [41]

Answer:

The water bottle sign or configuration refers to the shape of the cardiac silhouette on erect frontal chest x-rays in patients who have a very large pericardial effusion. Typically the effusion has accumulated over many weeks to months (e.g. in patients with malignancy) and the pericardium has gradually stretched.

quzilet Which of the following occurs when DNA is replicated? Group of answer choices One strand of the parent DNA is preserved;
Bad White [126]

Answer:

The two strands of the parent DNA are separated, and two daughter DNA strands are formed.

Explanation:

DNA replication is a complex process which replicates or produces new DNA molecule from the parent DNA molecule mediated by enzymes and ATP.

The mechanism of DNA replication is known as the semi-conservative mode in which one new strand of DNA is synthesized complementary to the one strand of DNA. To form a new DNA molecule both the strand of the DNA gets separated and then a new daughter strand is formed complementary to each parent strand.

Thus, the selected option is correct.
