Atoms
Which two subatomic particles' masses make up an atom's atomic mass?
Protons and neutrons
The amount of energy needed for a reaction to occur.
Activation energy
When the change in heat of a reaction is negative, the reaction is this.
Exothermic
Which letter in the alphabet is used as a variable that represents the equilibrium constant?
K
Opposities attract! The conjugate base of a strong acid is this type of base.
Weak
Atoms with the same atomic number but different masses are referred to as these.
Isotopes
Which step in a multi-step reaction determines the rate of reaction?
The slowest step
What is the added energy used for when a liquid is boiling?
Breaking IMFs
At equilibrium, the rate of the forward reaction and the reverse reaction are related in what way?
They are equal
The only acid with an element in group 17 that is not a strong acid contains this halogen.
Flourine
The measure of attraction exerted by an atom's nucleus on its electrons is referred to as this. It increases as you move up the periodic table.
Electronegativity
Decreases the activation energy of a reaction, allowing it to occur more frequently.
Catalyst
This constant is known as a substance's resistance to change in temperature
Specific heat
Increasing or decreasing the concentration of any substance in these two phases will shift the equilibrium.
Aqueous and gaseous
Whereas an ICE chart lets you find the concentration of a substance, this type of chart lets you find the amount of moles.
BCA
The height of a peak on a photoelectron spectroscopy graph represents this quantity.
Number of electrons
When the concentration of a reactant doubles, the rate quadruples! What is the reaction order with respect to the reactant?
A reaction is always thermodynamically favorable when the signs for enthalpy and entropy are...
Enthalpy negative
Entropy positive
When an ion present in a solution bonds with an ion form the added substance, what happens to the solubility of the added substance?
It increases
When a titration reaches its half equivalence point, this type of solution is present.
Ideal buffer
Halogens
What happens to the shape of a kinetic energy distribution graph when temperature increases?
Wider and shorter
When a gas becomes a solid without ever becoming a liquid, it is known as this phase change.
Sublimation
The side with more moles of aqueous ions
When at a temperature higher than 25C (NOT standard state), what happens to the pH and pOH of water?
They both increase
