Balancing Chemical Equations!

There are 6 types of Chemical Reactions!

1 SYNTHESIS: A + B = AB
Al + Cl = AlCl3
The balanced equation is: 2Al + 6Cl = 2AlCl3

2 DECOMPOSITION:
AB = A + B
AlBr3 = Al + Br2
The balanced equation is: 2AlBr3 = 2Al + 3Br2

3 SINGLE REPLACEMENT:
A + BC= B + AC
Ag(No3) + Zn = Ag + Zn(No3)2 The balanced equation is: 2Ag(No3) + Zn = 2Ag + Zn(No3)2

4 DOUBLE REPLACEMENT: AB + CD = AD + CB
MgCl2 + K2So4 = MgSo4 + KCl The balanced equation is: MgCl2 + K2So4 = 2KCl

5 NEUTRALIZATION: Acid + Base = Water + Ionic Salt
Ba(OH)2 + HCl = BaCl2 + H2O
The balanced equation is: Ba(OH)2 + 2HCl = BaCl2 + 2H2O

6 COMBUSTION:
Reaction with Oxygen
Mg + O2 = MgO
The balanced equation is: 2Mg + O2 = 2MgO
