Acid/Base/Solutions
Moles/liters of Solution
What happens to volume when pressure increases?
Volume decreases.
What equation is used to calculate heat gained or lost using specific heat?
q = mcΔT
What is oxidation?
Loss of electrons.
What does Bohr model describe?
Electrons in energy levels.
In a neutralization reaction of acid and base, what is the net ionic equation.
H++OH- --> H2O
What law is PV = nRT?
Ideal Gas Law
What is the sign of ΔH for exothermic reactions?
Negative
What must be the same on both sides of a balanced chemical equation?
no of atoms
Relationship between frequency and wavelength?
Inverse relationship.
Multiply the molarity by the number of ions produced per formula unit.
What happens to gas particle speed when temperature increases?
Particle speed increases.
What is Hess’s Law used for?
To calculate total enthalpy change using steps.
This type of reaction involves two compounds swapping ions to form two new compounds.
Double Displacement
What equation shows the energy of a photon?
E = hν
What is Dilution Equation
M1V1=M2V2
Define Dalton's law of Partial Pressure
The total pressure exerted by a mixture of gases in a container at constant V and T is equal to the sum of the pressures of each individual gas in the container.
What is the difference between path and state functions?
Path depends on route; state depends only on start/end.
What type of reaction involves oxygen and produces energy (like burning)?
combustion
What does photoelectric effect prove?
Light behaves as particles.
Phenomenon involves electrons being ejected from a metal surface when light shines on it
What is the difference between strong and weak acids?
Strong acids fully dissociate; weak acids partially dissociate.
Under what conditions does a real gas behave most like an ideal gas?
At high temperature and low pressure (when intermolecular forces and particle volume become negligible).
If heat is absorbed and work is done by system, what are their signs?
Positive and Negative
What is an oxidizing agent?
Gains electrons and causes oxidation.
What does the Heisenberg Uncertainty Principle state?
It is impossible to know both the exact position and exact momentum of an electron at the same time.
