Chapters 1-4
This term describes atoms bonded in specific geometrical arrangements.
What are molecules?
A homogeneous mixture consisting of a solute and solvent is called this.
What is a solution?
This principle states orbitals fill from lowest to highest energy.
What is the Aufbau principle?
This state of matter is compressible because particles are far apart.
what is a gas?
This type of unit cell has atoms only at the corners and a coordination number of 6.
What is simple cubic?
This law states that in a chemical reaction, matter is neither created nor destroyed.
What is the law of conservation of mass?
An ionic compound that completely dissociates in water is classified as this type of electrolyte.
What is a strong electrolyte?
First ionization energy does this as you move down a group.
What is decreases?
The strongest intermolecular force in pure substances, occurring when H is bonded to N, O, or F.
What is hydrogen bonding?
In a body-centered cubic unit cell, the number of atoms per cell equals this.
What is 2?
A property observed only when a substance undergoes a chemical reaction, flammability, corrosiveness.
What is a chemical property?
According to Avogadro’s law, equal volumes of gases at the same temperature and pressure contain equal numbers of these.
What are molecules (or moles)?
This quantity is the energy released when gaseous ions form a solid crystal.
What is lattice energy?
Water climbs up narrow tubes due to the combination of cohesive and adhesive forces in this process.
What is capillary action?
These atomic solids are held together only by dispersion forces and have extremely low melting points.
What are nonbonding atomic solids?
The formula that gives the relative number of atoms in a compound.
What is an empirical formula?
If two gases are at the same temperature, they must have the same value of this quantity.
What is average kinetic energy?
As bond order increases (single → double → triple), bond length does this.
What is decreases?
The temperature at which vapor pressure equals external pressure.
What is the boiling point?
The reason graphite can conduct electricity.
What is delocalized π electrons within sheets?
The type of error that consistently skews data either too high or too low.
What is systematic error?
This term refers to the part of the universe you're studying.
What is the system?
When there are six electron groups around a central atom, the electron geometry is this.
What is octahedral geometry (90°)?
When ice at 0°C is added to water, this step absorbs more energy: warming the ice or melting it?
What is melting the ice?
(because ∆Hfus >> warming from –10°C to 0°C)
The product formed when exactly two monomers join together.
What is a dimer?
