Q:

What name is given to the bond between water molecules?

A) Polar B) Polar covalent
C) Hydrogen D) None of the above
 
Answer & Explanation Answer: C) Hydrogen

Explanation:

The name given to the bond between water molecules is a hydrogen bond. These bonds occur between the slightly negative oxygen of one water molecule and the slightly positive hydrogen of another water molecule. Hydrogen bonding gives water special physical properties.

 

The differences in electronegativity between hydrogen and oxygen lead to an unequal sharing of electrons. Electronegativity measures how strongly an atom attracts electrons. Oxygen, with its higher electronegativity, pulls on the shared electrons more, giving the oxygen atom a partial net negative charge. The shared electrons spend less time with the hydrogen atoms; therefore, the hydrogen regions of water have partial positive charges.

A) forest degrading to dense taiga B) forest improving to tundras
C) forest improving to deserts D) forest degrading to sparse vegetation
 
Answer & Explanation Answer: C) forest improving to deserts

Explanation:

Desertification is a type of land degradation in which a relatively dry area of land becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife.

 

Conversion of a grassland or an already arid land into a desert through indiscriminate human actions magnified by droughts.

 

Hence, forest improving to deserts is refers to desertification.
