Question 9

Combustion reaction

Answer 9

Is the reaction of a substance with oxygen (usually from air) that proceeds with the evolution of heat and usually with a flame.

Question 10

Le chateliers principle

Answer 10

States that if a stress (change of conditions) is applied to a system in equilibrium the system will readjust (change the position of equilibrium) in the direction that best reduces the stress imposed on it.

Question 11

Oxidation-reduction reaction

Answer 11

Is a chemical reaction in which there is a transfer of electrons between reactants.

Question 12

Hydrogen based redox def

Answer 12

Oxidation is the process whereby a reactant in a chemical reaction loses one or more hydrogen atoms.

Reduction is the process whereby a reactant in a chemical reaction gains one or more hydrogen atoms.

Question 13

Electron based redox def

Answer 13

Oxidation is the process whereby a reactant in a chemical reaction loses one or more electrons.

Reduction is the process whereby a reactant in a chemical reaction gains one or more electrons.

Question 14

Oxygen based redox def

Answer 14

Oxidation is the process whereby a reactant in a chemical reaction gains one or more oxygen atoms.

Reduction is the process whereby a reactant in a chemical reaction loses one or more oxygen atoms.
