Concepts Covered:
- Mole to mole conversions: Converting between moles of different substances in a balanced chemical equation. $aA + bB \rightarrow cC + dD$ , where $a$ moles of A react with $b$ moles of B to form $c$ moles of C and $d$ moles of D.
- Mole to grams conversions: Converting from moles of a substance to its mass using the molar mass as a conversion factor. $mass = moles \times molar \, mass$ .
- Grams to mole conversions: Converting from mass of a substance to its amount in moles using the molar mass as a conversion factor. $moles = \frac{mass}{molar \, mass}$ .
- Grams to grams conversions: Converting from the mass of one substance to the mass of another substance using stoichiometric ratios and molar masses.
- Limiting reactants: The reactant that is completely consumed in a chemical reaction, determining the maximum amount of product that can be formed.
- Percent yield: The ratio of the actual yield to the theoretical yield, expressed as a percentage. $\frac{Actual \, Yield}{Theoretical \, Yield} \times 100$
Number of Questions: 50

Concepts Covered:
- Solids: Matter with definite shape and volume; particles are tightly packed and maintain fixed positions.
- Liquids: Matter with definite volume but no definite shape; particles are close together but can move past each other.
- Gases: Matter with no definite shape or volume; particles are widely separated and move randomly.
- Phase changes: Transitions between solid, liquid, and gas phases (e.g., melting, boiling, freezing, condensation, sublimation, deposition).

Concepts Covered:
- Dalton's Law: The total pressure exerted by a mixture of gases is the sum of the partial pressures of each individual gas. $P{total} = P1 + P2 + … + Pn$
- Ideal Gas Law: Relates pressure, volume, temperature, and the number of moles of a gas. $PV = nRT$ , where:
- $P$ = pressure
- $V$ = volume
- $n$ = number of moles
- $R$ = ideal gas constant
- $T$ = temperature
- Gas Stoichiometry: Application of stoichiometry to reactions involving gases, often using the ideal gas law to relate gas volumes to amounts.

Concepts Covered:
- Molarity: The number of moles of solute per liter of solution. $M = \frac{moles \, of \, solute}{liters \, of \, solution}$
- Solutions: Homogeneous mixtures of two or more substances.
- Dilutions: The process of reducing the concentration of a solution by adding more solvent. $M1V1 = M2V2$ , where:
- $M_1$ = initial concentration
- $V_1$ = initial volume
- $M_2$ = final concentration
- $V_2$ = final volume

Concepts Covered:
- Specific heat: The amount of heat required to raise the temperature of one gram of a substance by one degree Celsius (or Kelvin). $q = mc\Delta T$ , where:
- $q$ = heat
- $m$ = mass
- $c$ = specific heat capacity
- $\Delta T$ = change in temperature
- Entropy: A measure of the disorder or randomness of a system.
- Endothermic and exothermic reactions:
- Endothermic reactions: Reactions that absorb heat from the surroundings (positive $\Delta H$ ).
- Exothermic reactions: Reactions that release heat to the surroundings (negative $\Delta H$ ).
- Heat of formation: The change in enthalpy during the formation of one mole of a substance from its constituent elements in their standard states.
- Bond energy: The energy required to break one mole of a particular bond in the gaseous phase.

Concepts Covered:
- Acids: Substances that donate protons (H+) or accept electrons.
- Bases: Substances that accept protons (H+) or donate electrons.
- pH calculations: A measure of the acidity or basicity of a solution. $pH = -log[H^+]$
- Concentration calculations: Determining the amount of solute in a given volume of solution.
