What are the properties of transition metals?
100
The electrostatic attraction between a pair of electrons and positively charged nuclei
What is a covalent bond?
100
A measure of the heat energy contained within a substance.
What is enthalpy?
100

What is the rate of a reaction?
200
The ability of an atom to attract electrons in a covalent bond.
What is electronegativity?

The d-subshell is complete in Zn and Zn2+

Why is zinc not a transition metal?

200
Soluble in polar solvents but not non-polar solvents.
What is an ionic compound?
200
A reaction that results in an increase in enthalpy of the products.
What is an endothermic reaction?
200
Temperature, concentration, particle size, pressure and catalysts.
What are the factors that influence reaction rates?
300
They are good conductors of heat and electricity, are soft, very reactive and when reacting with water they form compounds of high pH
What are the alkali metals?
300
A species that uses a lone pair of electrons to form a coordinate bond with a metal ion?
What is a ligand?
300
109.5 bond angle
What is the bond angle in a tetrahedral structure?
300
The enthalpy change for a particular chemical reaction is independent of the route the reaction.
What is Hess's law?
300

A reaction in which the rate is directly proportional to the concentration of a reactant.

What is a first-order reaction?

400

2KBr + Cl2  ->  2KCl + Br2

2KI + Br2  ->  2KBr + I2

What are displacement reactions?

400
A catalyst in a different state of matter to the reactants?
What are heterogeneous catalysts?
400
The molecular geometry with 2 bonding electron domains and 2 non-bonding pairs of electrons.
What is a V-shaped or bent structure?
400
The enthalpy change when 1 mole of an ionic solid is separated into gaseous ions under standard conditions.
What is the lattice enthalpy?
400
The power to which the concentration of each reactant is raised in the rate equation.
