more aqueous. How hydrogen yond, 5. Both oxygen atoms in acetic acid (CH3CO₂H) are capable of hydrogen bonding, a feature that contributes greatly to the high boiling point of pure acetic acid. In water This also acetic acid Ce molecules hydrogen bond with water molecules, a factor which increases the solubility of linos acetic acid in water. Depict all possible hydrogen bonds between water molecules and each oxygen of a molecule of acetic acid. Use a dotted line to highlight each hydrogen bond.

1. Water is necessary for life on Earth. Water is made up of hydrogen and oxygen atoms (H2O); however, biological life in water depends on another form of oxygen. These organisms need molecular oxygen (O2), which they use to perform aerobic respiration. This molecular oxygen fits into spaces between water molecules and is available for aquatic organisms to use. How do you think molecular oxygen gets into the water? Choose two of the following choices. Select all that apply: From the oxygen atoms that are part of the water molecules. From oxygen that dissolves into water from the atmosphere. From oxygen that is given off by aquatic organisms during respiration. From oxygen that is given off by aquatic plants during photosynthesis.
