Answer:- Water is an electronegative molecule.
Explanation:
A molecule cannot be electronegative. Rather the atoms in a molecule may be electronegative. This first statement does not account for the hydrogen bonding in water at all because it is incorrect. However, the other statements in the question sheds more light on the nature of hydrogen bonding in water molecule.
Answer:
a fossil
Explanation:
Petrified wood is a fossil. It forms when plant material is buried by sediment and protected from decay due to oxygen and organisms. Then, groundwater rich in dissolved solids flows through the sediment, replacing the original plant material with silica, calcite, pyrite, or another inorganic material such as opal.
