Hi there!
<u>Electronegativity</u> is the concept of how likely an atom is to attract the shared molecules in one of these bonds to itself. We know the molecule water is made up of two hydrogens and one oxygen. The electronegativity of hydrogen is 2.2, and oxygen 3.4. An <u>ionic bond</u> needs at least a difference in electronegativity of 1.6. As the difference is less than that, we can say that water is a covalent molecule. This then wipes out choice B, because it is not ionic, and C, as we have seen it is actually covalent.
Now, we can see the difference in electronegativity between oxygen and hydrogen is still 1.2. This means that while it is not at the point for there to be an ionic bond, there is still a difference in attraction, where the electrons will tend to favor the oxygen more and 'hang around it' more. As electrons are <u>negatively charged</u><em><u>,</u></em> this means that the oxygen will gain a slightly negative charge. This then makes the molecule polar, because it now has a charge within the molecule. This means we have our answer, choice D.
In terms of hydrophobic molecules - they tend to be ones without a charge. (If you're interested in this kind of stuff, I'd search hydrophobic up, and possibly also look into hydrogen bonds).
Hope this helps! Feel free to ask me any other questions you have about this specific problem.
Answer:
A <u>fetal death</u> is death prior to the complete expulsion or extraction from its mother in a hospital facility, of a product of human conception (fetus and placenta), irrespective of the duration of the pregnancy and without any signs of life.
Explanation:
Due, to lack of nutrition or care some mothers loses there new born before the delivery, while most of the time such miscarriages results in the death of the fetus that is yet to be developed properly inside the womb of its mother. It all can happen due to mental, emotional, or physical stress on the female. However, it can be prevented by providing proper care to the mother and having the best of procedures to deal with any situation faced during the development of the fetus or offspring during the tenure of pregnancy.
