Question

Write down the types of chemical reaction along with example.

Answer 1

2Hgo = 2Hg+O2 is decomposition reaction

C+O3 = Co2 is combination reaction

2Al + 3H2So4 =Al2(So4)3 + 3H2 is displacement reaction

AgNo3 + NaCl = AgCl + NaNo3 is double displacement reaction

Answer 2

Answer:

There are 4 types of chemical reactions

1. chemical combination reaction

2. chemical decomposition reaction

3. displacement reaction

4. double decomposition reaction

1. chemical combination reaction:

A + B ___ AB

C+O2 ___ CO2

2. chemical decomposition reaction:

AB ____ A+ B

2H2O ___ 2H2 + O2

3. Displacement reaction:

Zn + 2HCl ____ ZnCl2 + H2

4.Double displacement reaction:

BaCl2 + Na2SO4 _____ BaSO4 +2 NaCl
