Hydrogen bonds give water which of the following properties? 1. high pH low pH the ability to resist temperature changes 2. the
Furkat [3]

Answer:

3. into ice, which is denser than liquid water.

Explanation:

Water molecules are held together by hydrogen bonds. The bonding is usually between the hydrogen atoms of one water molecules, and oxygen atom of neighboring  water molecules. Structurally,  both oxygen and  hydrogen atoms  pulls the electon towards themselves.Thus both atoms share   electron by covalent bonding.

However, because oxygen  has a strong positively charged nucleus it pulls the electron more to itself than oxygen. Thus oxygen is partially negative and oxygen is partially positive. This interactions take place among  all the oxygen and hydrogen atoms in water molecules. . The unequal charge distributions is called dipole and the attraction between oxygen and hydrogen is called  hydrogen bonding .

The  orientation of hydrogen and oxygen molecules from dipole -dipole  interactions of hydrogen bonding makes the  oxygen and hydrogen atoms in ice to be pushed apart well spaced out in ice, making them less dense than liquid  water  where they were aggregated.  Thus from the question option C is correct.

Which of the following best explains why a structural formula of a chemical compound is more useful than a molecular formula?
Fittoniya [83]

Answer: Both formulas identify the specific atoms in a particular compound. However, a structural formula also shows how the atoms in a compound are bonded together.

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

Structural formula is the formula which depicts the actual number of atoms of each element present in the compound by showing the bonding between the atoms.

Lewis structures show the valence electrons around each atom present in the compound.
