Reaction Prediction

Synthesis A synthesis reaction will occur provided the two the elements involved are capable of demonstrating opposite valences.

1a. Formation of binary compounds

A + B AB

H2 + Cl2 Mg + Br2

Na + Cl2

2b. Metal-oxide + H20 base CaO + H20

Na2O + H20

2c. NM-oxide + H2O acids SO2 + H2O

CO2 + H2O

Decomposition Needs heat, light, electricity

Decomposition of a substance by electricity is called electrolysis

2a. Binary Compound AB A + B

HgO NaN3

2b. M-carbonates: MCO3 M-oxides +

CO2 CaCO3

Na2CO3

2c. M-hydrogen carbonate: MHCO3 MO + H2O +

CO2

NaHCO3

d. M-hydroxides: MOH MO + H2ONaOH Ca(OH)2

e. M-chlorates: MClO3 MCl + O2

KClO3

f. Oxyacids :acid NMO + H2O

H2CO3

H2SO4

3a Metal – Metal replacement A + BC AC+B

Al + Fe(NO3)2

Al + ZnCl2

Co + NaCl

Single Replacement

3b. Active metal (group 1 &2) replaces H from

water: M + H2O MOH + H2

Na + H2O

Li + H2O

? Will it replace hydrogen from H2O? …….. Look on chart

3c. Active Metal replaces H from acid:

M + HX MX + H2

Mg + HCl Zn + HCl

Zn + H2SO4

?will it replace H from acids …..look on chart?

3d. Halide – Halide replacementone halogen replace another halogenD+ BC BD+C

Cl2 + KBr

F2 + NaCl

Br2 + KCl

F2

Cl2

Br2

I2

Identify the element that replaces hydrogen from acids but cannot replace tin from compounds?

According to the table, what is the most active transitional metal?

Double Replacement4a. Formation of a (ppt) from a solution

l. Both reactants must be soluble2. All DR will produce a (ppt), (g), H2O.3. must use solubility chart

KI + Pb(NO3)2

Ba(NO3) + Na2SO4

****4b. Acid + Base Neutralization Hfirst end (OH)

HCl + NaOH

H2SO4 + Ba(OH)2

HNO3 + Ca(OH)2

HC2H3O2 + Ba(OH)2

H2CO3 + Ca(OH)2

H3PO4 + K(OH)

1. NaI + CaCl2

2. HNO3 + Mn(OH)2
