Use the "like dissolves like" principle to explain the solubility experiments that you did with ethanol, pentanol, kerosene, and water.
Answer: A small puddle of each substance was placed on the reaction surface. Next, a sample of KI was placed in each puddle. KI is ionic and polar so it would dissolve in polar solvents. The polarity of the solvents would be ranked bases on how quickly the KI dissolved.

- Gas behavior is based on the following assumptions of the _______
- If bond order is greater than ____, then the substance can exist.
- p orbitals combine to form one ____ and one _____ molecular orbital and two _____ and two ____ molecular orbitals
- s orbitals combine to form a ____ and a ___ molecular orbital.
- _____ tells if a bond between two atoms is favorable. Anything greater than 0 is favorable.
- Atomic orbitals are described by _____ functions: combine constructively and destructively.
- ______ are generated by the combination of atomic orbitals from different atoms.
- A ________ is an orbital for a molecule rather than an atomic orbital.
- _____ is repelled and has all paired electrons.
- ______ is attracted to magnetic field and has unpaired electrons.
- ____-bonds restrict rotation of parts of the molecule, because the unhybridized p-orbitals must remain parallel.
- A ____-bond is generated from overlap of parallel unhybridized p orbitals.
- A _____-bond is generated from direct overlap of hybridized or unhybridized orbitals.
- In a double bond, the second pair of electrons is shared between parallel (unhybridized) p orbitals. this type of bond is called a __ bond.
- In a double bond, one pair of electrons is shared between axially overlapping orbitals (hybridized or unhybridized). this type of bond is called a _____ bond.
- The number of hybrid orbitals required by an atom is equivalent to the number of ________
- _____ of the atomic orbitals - the valence atomic orbitals combine to generate equivalent hybrid orbitals.
- A ______ bond is generated by overlap of two orbitals, one from each bonding atom.
- If any of the pairs is non-bonding or bonded to a different atom, then it will likely be _____
- If all of the electron pairs around the central atom are bonding to the same atoms, then it is likely _______
- The ______ bonds must be asymmetrically arranged around a central atom - the dipole moments of each polar bond cannot cancel each other out.
- A central atom has a non-bonding pair, a single bond, and a double bond. What is the approximate bond angle?
- A central atom has a non-bonding pair, a single bond, and a double bond. What is the molecular geometry?
- A central atom has a non-bonding pair, a single bond, and a double bond. What is the electron domain geometry?
- The _______ the bond order, the more space the domain requires due to greater electron - electron repulsion.
