Atomic Structure
Surrounded by empty space, it is this location that you can find protons and neutrons.
What is the nucleus?
A property that is high for metals, covalent networks, and ionic salts, but low for covalent molecules.
What is boiling point?
A type of chemical reaction in which causes things to feel colder.
What is an endothermic reaction?
A type of intermolecular force that can be found in all molecules.
What are dispersion forces?
The term used to describe a solution that cannot dissolve any more of a solute.
What is a saturated solution?
The main theory used to explain why rates of reaction change.
What is collision theory?
Atoms that hold an electrical charge due to a difference in electron and proton numbers.
What are ions?
What are covalent networks?
A type of reaction in which the reactants have more potential energy than the products.
The intermolecular force responsible for giving water its unusual properties, including a high surface tension and boiling point.
What are hydrogen bonds?
The person who described acids as chemicals that produce hydrogen ions in solution, and bases as chemicals that produce hydroxide ions in solution.
Who is Arrhenius?
The change to a chemical phase that causes the rate of a reaction to increase.
What is increasing surface area?
This is the name used to refer to the relationship of particular atoms that have different masses - for example, carbon-12 and carbon-13.
What are isotopes?
Examples of different material arrangements - for example, diamond, graphite, graphene, and buckyballs.
What are allotropes?
The symbol used to describe the amount of heat released or absorbed during a chemical reaction.
What is \DeltaH?
A technique often used to find the components of a complex mixture.
What is chromatography?
The scale used to measure the concentration of hydrogen ions in solution.
What is the pH scale?
A physical property that behaves similar to pressure when describing changes in reaction rate.
What is concentration?
A phenomenon that is often used to determine the identity of different metals - for example, in AAS.
What is absorption of light?
The size for nanoparticles; commonly used as catalysts because of their smaller size.
What is between 1 and 100nm?
The term used to describe the ficticious chemical species in a reaction that has the most enthalpy.
What is the transition state?
A property of gasses that increases when the volume of gas is decreased.
What is pressure?
Something that is formed whenever silver is added to a solution of halides.
What is a precipitate?
A reagent that causes chemical reactions to go faster without decreasing the activation energy of that reaction.
What is a catalyst?
The following element, when run through a mass spectrometer, will give the following data:
Mass: 12amu, abundance: 99%
Mass:13amu, abundance: 1%
What is carbon?
A molecule containing 4 carbons and 10 hydrogens, where one of the carbons forms a methyl chain.
A type of fuel that is considered to have a "net 0" effect on carbon emissions.
What are biofuels?
The volume of 1 mole of gas occupied at a temperature of 273.15K and pressure of 1.00 bar.
What is 22.71?
The type of chemical that, when combined with a base, will produce ammonia gas.
What are ammonium salts?
What are enzymes?
A phenomenon best explained by some atoms having an increasing atomic radius, but for others by having a decreased atomic radius.
What is reactivity?
An organic reaction in which one chemical reactant is added to a second reactant, resulting in just one product.
What is an addition reaction?
The type of chemical reaction that occurs when a hydrocarbon produces lots of soot alongside carbon oxides.
What is incomplete combusion?
The intermolecular forces you would largely present in acetone (CH2O), but not barely present in a water-acetone mixture.
What are dipole-dipole forces?
The derived unit used to describe the concentration of a chemical.
What is molarity (M)?
Often used to convert nitrogenous oxides into nitrogen gas.
What are catalytic converters?
