The use of electricity to break down a molecule into smaller units
A molecule that has slight positive and negative charges due to an imbalance in the way electrons are shared
A liquid substance capable of dissolving other substances
A substance that is dissolved in a solvent
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
Water that has certain dissolved ions in it – predominately calcium and magnesium ions
A certain molecule is composed of atoms that all pull on electrons with the same strength. Will this molecule be polar?
Baking soda dissolves in water. Will it dissolve in vegetable oil (a nonpolar substance)?
Carbon tetrachloride will not dissolve in water. Is it most likely to be made up of ionic, polar, or nonpolar molecules?
Suppose you were able to count the molecules in a substance. Which would have more molecules, 1 liter of liquid water or 1 liter of ice?
Which would have more molecules, 1 liter of liquid butter or 1 liter of solid butter?
What is responsible for water being liquid at room temperature as well as for water’s cohesion?
What causes surface tension?
Why is water harder in certain regions of the world than in others?
There are more ion-containing rocks in those regions
