Which compound is more ionic?
NaF or AgF
NaF
Metallic atoms with very loose electrons for a lattice of nuclei held together by a sea if electrons or metallic bonds.
What is Metallic
What is a solid that forms when two aqueous solutions mix
What is a Precipitate
What is a catalyst?
A substance that, when present, speeds up a reaction but remains unchanged.
Is a Li-O or O-H bond/attraction stronger? Why?
The Li-O bond is stronger than the O-H bond because even though they have the same charge, Li is more metallic
Metal and nonmetal atoms form a lattice of alternating positive and negative ions held together by ionic bonds.
What is Ionic
Name evidence of a chemical reaction
Precipitate, Color change, Light, Change in temperature, Sounds, Production of gas, Formation of a new substance.
What is the rate of reaction determined by?
The slowest elementary step in a reaction.
O (2 lone pairs) 2 bonds to O (1 lone pair) 1 bond to O (3 lone pairs)
Nonmetal atoms form a lattice structure held together with covalent bonds.
What is Network
What are the five types of reactions
Composition (synthesis), decomposition, Single replacement, Double replacement, Combustion.
What order is this reaction?
Rate= k[D]o[C]1
What is First order
Give the molecular geometry and bond angle of BF3
Trigonal Planar, 120o
Nonmetal atoms form molecules with covalent bonds. The molecules are held together in a solid by intermolecular forces of attraction.
What is Molecular
What does a redox reaction represent?
Represents the transfer of electrons from element to another.
Solve the First Order Integrated Rate law for time
(ln(Ao/AT))/(k)
Put the following elements in decreasing metallic character.
Ba, Ca, Ge, Se, Ne, Cu, Ga
Ba, Ca, Cu, Ga, Ge, Se, Ne
Draw a particle diagram of Fe melting.
First diagram should contain a rigid lattice. Second diagram atoms should be loose and disorganized but settled at the bottom of a container.
What is the purpose of Oxidation numbers?
It is a method of tracking the "ownership" of electrons by atoms.
What are the ways to measure changes of a reaction?
Volume, Pressure change, Molarity, Mass loss/gained by the reaction, the pH of the solution.
