Thermochemical Principles
The definition of enthalpy
What is the total heat content of a system?
The shape and bond angle of a methane molecule (CH4)
What is tetrahedral, 109?
The ability of an atom to attract a bonding pair of electrons to itself
What is electronegativity?
The name of the coffee shop in the sitcom Friends
What is Central Perk?
The number of years Miss Hamilton has been teaching
What is 3 years?
-150kJ
Electron pairs that are not involved in bonding
What are lone pairs?
The term for when inner electrons reduce the pull of the nucleus on the outermost electrons
What is electron shielding?
The smallest country in the world
What is Vatican City?
The name of Miss Hamilton's dog
What is Bear?
An apparatus used for measuring precise changes in temperature
The type of bond formed when two atoms with different electronegativities share electrons unequally.
What is polar covalent bond?
This periodic trend decreases across a period because of an increased effective nuclear charge causing the atom to hold onto electrons more tightly.
What is atomic radius?
The largest mammal on Earth
What is the blue whale?
Where Miss Hamilton is travelling to next year
What is the standard enthalpy of formation?
This term refers to the uneven distribution of electron density within a polar bond, creating partial charges
What is a dipole?
The definition of ionisation energy
What is the energy required to remove the least tightly bound electron from one mole of atoms in the gaseous state
What is Poseidon?
Miss Hamilton's favourite subject at school.
The definition of Hess's Law
This law states that the total enthalpy change of a reaction is the same, regardless of the pathway taken.
The shape of a molecule with five bonding pairs and one lone pair
What is square pyramidal?
The measure of the attraction between a nucleus and its outermost electrons.
What is effective nuclear charge?
The country the tallest building in the world is located in
What is United Arab Emirates?
