Question

Pre-Laboratory Question Balance each of the following equations, and classify each of the reactions by type. Reaction Equation Type of Reaction 1. KClO3 → KCl + O2 2. Na + O2 → Na2O2 3. KI + Pb(NO3)2 → KNO3 + PbI2 4. Cu + AgNO3 → Cu(NO3)2 + Ag 5. C3H8 + O2 → CO2 + H2O + Heat 6. Zn + HCl → ZnCl2 + H2

Answer 1

Step-by-step explanation:

1) 2 KClO3-->2 KCl + 3 O2 Decomposition

2) 2 Na + O2 --> Na2O2 Synthesis/ composition/both names are accepted

3) 2KI + Pb(NO3)2 --> 2KNO3 + PbI2 Double displacment or double replacment (which ever name your book uses)

4) Cu + 2 AgNO3 ---> Cu (NO3)2 + 2 Ag Single displacment or replacment

5) C3H8 + 5O2 --> 3CO2 + 4H2O combustion

6) Zn + 2 HCl --> ZnCl2 + H2 Single replacment or single displacment
