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

1) 2 KClO₃ → 2 KCl + 3 O₂ decomposition

2) 2 Na + O₂ → Na₂O₂ direct combination

3) 2 KI + Pb(NO₃)₂ → 2 KNO₃ + PbI₂ double displacement

4) Cu + 2 AgNO₃ → Cu(NO₃)₂ + 2 Ag single displacement

5) C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O + heat  combustion

6) Zn + 2HCl → ZnCl₂ + H₂ single displacement

decomposition reaction -  when you heat a compound (for a certain amount of time and temperature) it will transform in simpler substances

direct combination - simpler elements will react to each other to form a chemical compound

double replacement - it is a reaction of the following type

AB + CD →  AC + BD

single replacement - it is a reaction of the following type

A + BC →  B + AC

combustion - when substances (usually organic compounds like hydrocarbons) react with oxygen forming oxides and heat
