Define It!
A liquid substance capable of dissolving other substances.
What is a solvent?
Water is a molecule made up of what types of atoms linked together?
What are Hydrogen and Oxygen?
This is the chemical formula for calcium carbonate which has one calcium atom, one carbon atom, and three oxygen atoms.
What is CaCO3?
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?
This is responsible for water being a liquid at room temperature as well as for water's cohesion.
What is hydrogen bonding?
Water that has certain dissolved ions in it, predominately calcium and magnesium ions.
What is Hard Water?
Water is sometimes called this because it can dissolve nearly everything (not everything)!
What is a "near-universal substance".
This is how many atoms are in a molecule of ammonia which has a chemical formula of NH3.
What is four?
Water does not dissolve gasoline so it is most likely made up of this type of molecules.
What are nonpolar molecules?
This causes surface tension.
What is cohesion?
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?
A weak bond established between hydrogen molecules in one atom and oxygen molecules in another.
What is a hydrogen bond?
A certain molecule that is composed of atoms that all pull on electrons with the same strength.
What is a nonpolar molecule?
This allows water to have a high boiling point.
What are strong hydrogen bonds?
This causes water to be harder in certain regions of the world that others.
What is a higher amount of metal containing substances?
The use of electricity to break a molecule down into smaller units.
What is Electrolysis?
This phenomenon allows some things to float on the surface without breaking through.
What is surface tension?
Carbon tetrachloride will not dissolve in water so it is most likely made up of these types of molecules.
What are nonpolar molecules?
Daily Double
Hydrochloric acid HCI is a powerful acid often used in cleaning. H stands for hydrogen, CI stands for chlorine. Chlorine atoms can pull on electrons much more strongly than can hydrogen atoms because it is what kind of molecule?
What is polar
This is a substance that is dissolved in a solvent.
What is a solute?
A molecule that has slight positive and negative charges due to an imbalance in the way electrons are shared.
What is a Polar Molecule?
This is what makes water a liquid at room temperature while similar substances stay in gas form.
What is hydrogen bonding?
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?
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?
Epsom salts has the chemical formula MgSO4. How many atoms are there in a molecule of epsom salts (Magnesium Sulfate)?
What is 6?
