Chemical Bonding and Properties Quiz

Bonding and Water Properties

• Hydrogen bonds form between two polar molecules, such as between two water molecules.
• Water's high specific heat capacity allows it to buffer temperature.
• Nonpolar covalent bonds form when elements have about the same electronegativity and share electrons equally, such as in carbon-hydrogen bonds.

Water Properties

• Water's low density form floats as ice due to its hydrogen bonding, which results in a crystalline structure with empty spaces.

Elements and Nucleosynthesis

• The heaviest naturally occurring element formed in supernova explosions is not specified.
• The heaviest element formed from nucleosynthesis is not specified.

Biomolecules

• The process of joining monomers together and removing a water molecule is called dehydration synthesis.
• Water's polarity allows it to attract other polar molecules.
• Three hydrogen bonds are formed between cytosine (C) and guanine (G) in a DNA molecule.
• The process of splitting a biomolecule into its monomer components using water is called hydrolysis.
• A protein is a long strand of amino acids folded into a 3D shape.
• Phosphodiester bonds are the covalent bonds that link one strand of DNA backbone together.
