配平H2S+Na2O2+H2O-Na2SO4+NaOH

配平H2S+Na2O2+H2O-Na2SO4+NaOH NaCrO2+Na2O2+H2O------ Na2CrO4+NaOH 配平 H2SO4+NaOH------Na2SO4+H2O配平,写出原子质量. Na2Sx+NaClO+NaOH=Na2SO4+NaCl+H2O NaSx+NaClO+NaOH-Na2SO4+NaCl+H2O H2SO4+2NAOH=NA2SO4+H2O 2NaOH+SO3=Na2SO4+H2O中Na2SO4沉淀吗 Nacl NaoH NA2O2 O2 H2S H2O2 NH4CL HCL 中 硫化氢和氢氧化钠反映H2S + 2NaOH = Na2S + H2O(H2S足量)H2S + NaOH = NaHS + H2S+NaOH为什么生成NaHS+H2O/Na2S+2H2O H2S+HNO3____S+NO+H2O 配平 2Na2O2+2H2O=4NaOH+O2↑
