Question

Classify each reaction as synthesis, decomposition, single displacement, or double displacement (a) H2 + O2 = H2O (b) N2H4(l)—> NH3(g)+N2(g) (c) H2SO4 + NaOH —> H2O+Na2SO4 (d) Al2 (CO3) -^-> Al2O3 + CO2 (e) NH4I+ Cl2 —-> NH4Cl+I2

Answer 1

a) H2 + O2 = H2O -----> Synthesis

b) N2H4(l)—> NH3(g)+N2(g) ----> Decomposition

c) H2SO4 + NaOH —> H2O+Na2SO4 ----> Double-displacement

d)Al2 (CO3) -^-> Al2O3 + CO2----> Decomposition

e) NH4I+ Cl2 —-> NH4Cl+I2 ----> Single displacement
