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
Fe(ClO3)2
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
3. AgNO2 + BaSO4
4. LiBr + AgNO3
practice
5. CombustionHydrocarbon + Oxygen Carbon dioxide + water
Methane CH4
Ethane C2H6
Propane C3H8
Butane C4H10
Octane C8H18
