Frage 1
Frage
Define standard enthalpy change of combustion
Antworten
-
The 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
-
The 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
-
The 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

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

-
The removal of a molecule from a saturated molecule to make an unsaturated molecule
-
The formation of a solid from a solution during a chemical reaction. Precipitates are often formed when two aqueous solutions are mixed together
-
A reaction in which an atom or group of atoms is replaced with a different atom, or group of atoms
Frage 6
