1Define standard enthalpy change of combustion
- AThe enthalpy change that takes place when one mole of a substance reacts completely with oxygen under standard conditions, all reactants and products being in their standard conditions
- BThe enthalpy change that takes place when one mole of a compound in its standard state is formed from its constituent elements in their standard states under standard conditions
- CThe enthalpy change that accompanies a reaction in the molar quantities expressed in a chemical equation under standard conditions, all reactants and products being in their standard states
2Define the standard enthalpy change of formation

4Define "addition reaction"
- AA reaction in which a reactant is added to an unsaturated molecule to make a saturated molecule
- BA reaction in which a more reactive element displaces a less reactive element from an aqueous solution of the latter's ions.
- CThe removal of a molecule from a saturated molecule to make an unsaturated molecule
- DThe formation of a solid from a solution during a chemical reaction. Precipitates are often formed when two aqueous solutions are mixed together
- EA reaction in which an atom or group of atoms is replaced with a different atom, or group of atoms
5Define "displacement reaction"
- AA reaction in which a reactant is added to an unsaturated molecule to make a saturated molecule
- BA reaction in which a more reactive element displaces a less reactive element from an aqueous solution of the latter's ions.
- CThe removal of a molecule from a saturated molecule to make an unsaturated molecule
- DThe formation of a solid from a solution during a chemical reaction. Precipitates are often formed when two aqueous solutions are mixed together
- EA reaction in which an atom or group of atoms is replaced with a different atom, or group of atoms
6Define "elimination reaction"
- AA reaction in which a reactant is added to an unsaturated molecule to make a saturated molecule
