What is electrolysis?
The elements that make up a molecule of water.
What are hydrogen (2) and oxygen (1)?
A substance that is dissolved into a solvent.
What is a solute?
The property that attracts molecules of water to one another.
What is hydrogen bonding?
The item required in every experiment in this book.
What are safety glasses?
A liquid substance capable of dissolving other substances.
What is a solvent?
The process that was not used before Drs. Fleischman and Ponds announced their cold fusion phenomenon.
At atom that has a net electrical charge.
What is an ion?
The state of matter where water molecules are closest together.
What is liquid?
The property of water displayed in experiment 4.2 (with the comb).
What is polarity?
A molecule that has slight positive and negative charges due to an imbalance in the way electrons are shared.
What is a polar molecule?
The symbols that help us to understand the chemical makeup of a substance.
What is a chemical formula?
The "near universal solvent."
What is water?
The effect of cohesion at the surface of a liquid.
What is surface tension?
The solvent and the solute in experiment 4.1 (with the battery & test tubes).
What are water and Epsom salts?
Water than has certain dissolved ions in it - predominantly calcium and magnesium ions.
What is hard water?
The force that links the hydrogen and oxygen atoms together in a molecule of water.
What is a chemical bond?

What are polar molecules or ions?
The small tubes in plants that transport water.
What are xylem?
The process used to break apart the water molecules in experiment 4.1 (with the battery & test tubes).
What is electrolysis?
The phenomenon that occurs when individual molecules are so strongly attracted to each other that they tend to stay together, even when exposed to tension.
What is cohesion?
The Latin name for iron.
What is ferrum?
The result of dissolving a substance into a liquid.
What is a solution?
A chemical process called ion exchange that removes calcium and magnesium from water.
