QUESTION 10 Classify the following reactions as synthesis (redox), synthesis(non-redox), decomposition(redox), decomposition (non-redox), combustion, single replacement, double replacement w/ precipitation, double replacement w/ gas produced or double replacement w/ acid base. [Note: A synthesis reaction can also be called a combination reaction.] Cu(NO3)2 (aq) + Pb(s) Cu(s) + Pb(NO3)2 (aq) A. Combustion 4 Fe (s) + 3 02 (g) 2 Fe203 (s) B. Double replacement/acid base - C. Synthesis (non-redox) D. Decomposition(non-redox) ✓ 2 NH3 (9)→ N2 (s) + 3 H2(g) ✓ Pb(NO3)2 (aq) + NaBr (aq) CaCO3 (s) CaO (s)+ CO2 (9) E. Synthesis(redox) F. Double replacement / precipitation G. Single replacement H₂0 (1) + SO2(g) → H₂SO3(aq) H. 2 HCl(aq) + Mg(OH)2 (aq)- MgCl2 (aq) + 2 H₂O (1) CO2 (g) + 2 H₂O (9) 1. Double replacement w/ gas produced CH4 (s) + 2 O2 (g)- ✓CaSO3(s) + 2 HCI (g) CaCl2(aq) + SO2 (g) + H2O(1) - - - PbBr2 (s) + 2 NaNO3(aq) Decomposition(redox)
