Term
Combustion
Definition

Combustion of hydrocarbons (compounds that contain only hydrogen and carbon) produces carbon dioxide and water. "Combustion" implies that a fuel is reacting with oxygen.

CmHn + O2(g) → Co2(g) + H2O(L)

C3H8 + 5O2 → 3CO2 + 4H2O

Term
Precipitation 
Definition

Precipitation reactions can be recognized by the presence of a solid, insoluable ionic compound products in the reaction where aqueous reactants are combined. 

AX(aq) + BY(aq) → AY(s) + BX(aq)

Mg(NO3)2(aq) + Na2CO3(aq) → MgCO3(s) + 2NaNO3(aq)

Term
Gas-Forming Reactions
Definition

Gas forming reactions can be recognized by the presence of a gas-phase product (g) in a reaction in which the reactants are not gaseous (usually aqueous solutions). One reactant is acid or base.

CX(aq) + DY(aq) → CY(g) + DX(aq)

Term
Neutralization Reactions
Definition

Neutralization reactions (or acid base) occure when an acid and a base are the reactants, and the products are H2O and an ionic compound ("salt")

HX(aq) + BOH (aq) → BX(aq) + H2O(L)

HI(aq) + KOH(aq) → KI(aq) + H2O(L)

Term
Reduction-Oxidation 
Definition

Reduction-oxidation reactions can be recognized by noticing whether the oxidation numbers of any of the elements involved in the reaction changed between the reactant and the product side.

2Fe(s) + 3O2(g) → Fe2O3(s)

H2SO4(aq) + 8HI(aq) → H2S(aq) + I2(g) + 4H2O(L)

 

Term

Formation


Definition

Formation reactions involve the creation of a compound from its component elements in the standard states

element + element → compound

N2(g) + 3H2(g) → 2NH3(L)

 

Term
Decomposition
Definition

Decomposition reactions can be identified...

compound → element + element

2NH3(g) → N2(g) + 3H2(g)
