A resposta correta é: ( ) Synthesis reaction; Decomposition reaction; Double displacement reaction; Double displacement reaction. 2 H2(g) + O2(g) 2 H2O(g) é uma reação de síntese. H2CO3(aq) H2O(ℓ) + CO2(g) é uma reação de decomposição. Zn(s) + 2 HCℓ(aq) ZnCℓ2(aq) + H2(g) é uma reação de dupla troca. 2NaOH(aq)+H2SO4(aq) Na2SO4(aq)+H2O(ℓ) é uma reação de dupla troca.
