3) NH3 + HCl = NH4Cl
NH3 + H(+) + Cl(-) = NH4(+)+Cl(-) полное ионное
NH3 + H(+) = NH4(+) сокращённое ионное
NH4Cl + AgNO3 = NH4NO3 + AgCl(осадок)
NH4(+) + Cl(-) + Ag(+) + NO3(-) = NH4(+) + NO3(-) + AgCl(осадок) полное ионное
Cl(-) + Ag(+) = AgCl(осадок) сокращённое ионное
NH4NO3 + NaOH = NH3(газ) + NaNO3 + H2O
NH4(+) + NO3(-) + Na(+) + OH(-) = NH3(газ) + Na(+) + NO3(-) + H2O полное ионное
NH4(+) + OH(-) = NH3(газ) + H2O сокращённое ионное
4) S + O2 = SO2
n(O2) = n(S) = 2моль V(O2) = n(O2)*Vмоль = 2моль*22,4л/моль=44,6л
5) 2NH4Cl + Ca(OH)2 = 2NH3(газ) + СaCl2 + 2H2O
n(NH4Cl)=m/M=42/53,5=0,785моль
n(NH3,теор)=n(NH4Cl)=0,785моль V(NH3,теор)=n(NH3,теор)*Vмоль=0,785моль*22,4л/моль=17,585л
w=V(NH3)*100%/V(NH3,теор)=11,6л*100%/17,585л=65,965%
ответ: объёмный выход аммиака равен 65,965%.
