Advanced Synthesis

Simple compounds, called OXIDES can synthesize acids or bases.

Whether an acid or base is made depends on the type of oxide that is reacted.

Acids form from _____??___oxides.

Acids form from nonmetal oxides.

Bases form from __?????__ oxides.

Bases form from metal oxides.

NO2 + H2O ???

NO2 + H2O HNO3 H+ NO3- from list

Cs2O + H2O ??????

Cs2O + H2O CsOH

Decompositions

Decompositions and synthesis are ??????????

Decompositions

Decompositions and synthesis are OPPOSITES.

H2O ????

H2O H2 + O2

Fe2O3 ???

Fe2O3 Fe + O2

How to know what type is involved.

Combustion= an organic compound + O2 OR

active metal + O2

Synthesis= reactants are two elements OR oxide and water, ONE PRODUCT

Decomposition= ONE REACTANT
