Unit 2 - Bonding, Properties of Water and Biomolecules

Front

What makes water a universal solvent?

Back

Water dissolves more substances than anything else.

Front

What is the charge of the hydrogen atoms in a water molecule?

Back

The hydrogen atoms in a water molecule are positively charged.

Front

What occurs during the formation of ionic bonds?

Back

Ionic bonds involve the transfer of electrons.

Front

What property of water contributes to Seattle being warmer than Minneapolis in winter?

Back

High Specific Heat.

Front

What is the primary function of most enzymes?

Back

Most enzymes speed up chemical reactions.

Front

Define cohesion in the context of water properties.

Back

Cohesion is the attraction between water molecules due to hydrogen bonding.

Front

Define adhesion in the context of water properties.

Back

Adhesion is the attraction between water molecules and other substances.

Front

What is the significance of water's high specific heat?

Back

It allows water to absorb and retain heat, moderating temperature changes.

Front

How does water's density change when it freezes?

Back

Water expands and becomes less dense when it freezes, allowing ice to float.

Front

What role do hydrogen bonds play in the properties of water?

Back

Hydrogen bonds contribute to water's unique properties, such as high surface tension and specific heat.
