What is the difference between an amorphous and crystalline solid? Amorphous is disordered Crystal is ordered
True or False. Water has a relatively high vapor pressure. False
Why does water have a low vapor pressure? Hydrogen bonding holds water molecules back from evaporating
What are the bonds called between an oxygen and hydrogen atom in one molecule of water? Polar covalent bond
The bonds between adjacent water molecules are called _______? Hydrogen bonds
What is the name for a solid that is dissolved in a solution? Solute
What is the name for a liquid that does the dissolving in a solution? Solvent
It takes a lot of energy to melt ice. Why? Hydrogen bonding creates extra bond energy

What does the term like dissolves like mean when a chemist uses it? Polar solutes are dissolved (soluble) by polar solvents Nonpolar solutes are dissolved (soluble) in nonpolar solvents
What are the two types of heterogeneous aqueous systems? Colloids and Suspensions
What is a more common term for a homogeneous aqueous system? Solution
As individual solute ions break away from a crystal, the negatively and positively charged ions become surrounded by solvent molecules. What process is being described? Solvation
True or False. The structure of ice is an irregular closed framework of water molecules arranged like a honeycomb. False, regular open
A substance that interferes with the hydrogen bonding in water is known as a(n) ________. Surfactant
Many unique and important properties of water result from ________. Hydrogen bonding
Colloids, solutions, or suspensions. Which of these exhibits the Tyndall effect? Colloids and suspensions
What is an emulsion? A colloid formed when two liquids are mixed together.
Compare and contrast solutions, colloids, and suspensions based on particle size? Solutions – less than 1 nm Colloids – between 1 nm – 1000 nm Suspensions – greater than 1000 nm
Ionized gas. Plasma
Describe sublimation. Going from solid directly to gas
Describe condensation. Going from gas to liquid
Describe deposition. Going from gas directly to solid
Describe vaporization. Going from liquid to gas.
