The article "Ozone Hole on the Mend" mentions interesting details about the ozone layer. But what is the author's main point? In your own words, briefly describe what you think the main point of the article is.

Answer in explanation

Explanation:

The article by the author is an interesting read and contains a whole lot of facts.

The main point the author is driving at is that the ozone hole is getting a kind of healing from its otherwise thought depletion continuation.

What he is trying to say is that, although over the years there has been a rate of decline in the layer, a recent study has shown that the decline rate has in fact slowed down and the hole thought to be on regular depletion is in fact getting healed at a rate in which the depletion has slowed

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

the answer would be d : p
