Question

Name DateLab Section_ Results and Discussion - Experiment 6- Classification of Chemical Reactions For an extension to this experiment, see Acivity 35, Part C A. Classification of reactions. For each system record significant observations (e.g., white precipitate, gas evolution, heat evolution, color change, or NAR for no apparent reaction). For numbers 1-9 classify the potential reaction according to combination (CA), decomposition (D), combustion (CU), single replacement (SR), double replacement (DR) and balance the equations For numbers 10-15, record observations and complete, balance and classify any reactions that occur class 2. 3. 4. 6. lu Colrdhd 7. in ©2015 Cengage Lormg AllRights Reserved.

Explanation / Answer

1 balanced reaction

3 CaCl2 + 2 Na3Po4 = Ca3(Po4)2 + 6 NaCl
Reaction type: double replacement

2 balanced reaction

CuSO4 + 5H2O --> CuSO4.5H2O (blue vitriol)

Reaction type: synthesis

3

Cu(OH)2 = CuO + H2O

Reaction type: decomposition

4

Zn + 2 HCl = ZnCl2 + H2

Reaction type: single replacement

2 H2 + O2 = 2 H2O
Reaction type: synthesis
