What is Carbon's electron configuration?
This formula shows the lowest whole-number ratio of atoms in a compound.
What is the empirical formula?
The electrons in the outermost shell.
What are valence electrons?
Heat is transferred from the system to the surroundings.
What is an exothermic reaction?
A substance that can speed up a reaction, without being used up in the process.
What is a catalyst?
Different atoms of the same element that contain the same number of protons and electrons but a different number of neutrons.
What is an isotope?
This number is a representation of particles in a mole.
What is 6.02x10^23?
The strongest intermolecular force.
What is a Hydrogen Bond?
The measure of a system's thermal energy per unit temperature that is unavailable for doing useful work
What is entropy?
This is the minimum amount of energy required for a reaction to occur.
What is activation energy?
32
What is the maximum number of electrons in the 4th shell?
Experimental value/theoretical value x 100
What is the percentage yield formula?
The strongest bond
What is a covalent bond?
A reaction where the products are less thermodynamically stable.
What is an endothermic reaction?
Decreased particle size
What is increased surface area of reactants?
Every orbital in a sublevel is singly occupied before any orbital is doubly occupied. All of the electrons in singly occupied orbitals have the same spin
What is Hund's rule?
The law which relates the temperature and volume of a gas.
What is Charles' Law?
This symbol is used to show a partial charge.
What is a delta symbol?
A yellow flame.
What is a sign of incomplete combustion?
Zero order reaction
What is constant rate of reaction? (accept graph shows..)
There are large increases in ionization energy when the 2nd and 10th electrons are removed.
What is the ionization of Sodium/Potassium?
Molecules have finite volumes and attract one another
What is the reason real gases deviate from ideal behaviour at high pressures or low temperatures?
This molecular geometry has bond angles of 90 and 120 degrees.
What are the Trigonal Bipyramidal bond angles?
2.46 J g-1 degree C-1
What is the specific heat capacity of ethanol?
When the concentration doubles, the rate of reaction quadruples.
What is a second-order reaction?
