100
A liquid substance capable of dissolving other substances.
What is a solvent?
100
Water is a molecule made up of what types of atoms linked together?
What are Hydrogen and oxygen?
100
This is the chemical formula for calcium carbonate which has one calcium atom, one carbon atom, and three oxygen atoms.
What is CaCO3?
100
This is the chemical formula of a molecule of glucose which contains six carbon atoms, twelve hydrogen atoms and six oxygen atoms.
What is C6H12O6?
100
This is responsible for water being a liquid at room temperature as well as for water's cohesion.
What is hydrogen bonding?
200
Water that has certain dissolved ions in it, predominately calcium and magnesium ions.
What is Hard Water?
200
Water is sometimes called this because it can dissolve nearly everything (not everything)!
What is a "near-universal substance".
200
This is how many atoms are in a molecule of ammonia which has a chemical formula of NH3.
What is four?
200
Water does not dissolve gasoline so it is most likely made up of this type of molecules.
What are non polar molecules?
200
This causes surface tension.
What is cohesion?
300
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?
300
A weak bond established between hydrogen molecules in one atom and oxygen molecules in another.
What is a hydrogen bond?
300
A certain molecule that is composed of atoms that all pull on electrons with the same strength.
What is a non polar molecule?
300
This allows water to have a high boiling point.
What are strong hydrogen bonds?
300
This causes water to be harder in certain regions of the world that others.
What is a higher amount of metal containing substances?
400
The use of electricity to break a molecule down into smaller units.
What is Electrolysis?
400
This phenomenon allows some things to float on the surface without breaking through.
What is surface tension?
400
Carbon tetrachloride will not dissolve in water so it is most likely made up of these types of molecules.
What are non polar molecules?
400
Hydrochloric acid, HCl, is a powerful acid often used in cleaning. Chlorine atoms can pull on electrons much more strongly than can hydrogen atoms. The small negative charge lies with this atom.
What is the chlorine atom?
400
This is a substance that is dissolved in a solvent.
What is a solute?
500
A molecule that has slight positive and negative charges due to an imbalance in the way electrons are shared.
What is a Polar Molecule?
500
This is what makes water a liquid at room temperature while similar substances stay in gas form.
What is hydrogen bonding?
500
If 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?
What is liquid?
500
Butane is a gas at room temperature, but it is stored under pressure as a liquid in a butane lighter. The chemical formula is C4H10. Isopropyl alcohol is another liquid. Its chemical formula is C3H8O. Of the two, this liquid participates in hydrogen bonding.
What is isopropyl alcohol?
500
The chemical formula that might result from a botched experiment in which your test tube, which held hydrogen gas, had a crack in it causing the gas to slowly leak out of that crack (although not as quickly as the gas was being made by the experiment).
What is HO?
