Answer 1

2KMnO4+16HCl=2MnCl2+5Cl2+2KCl+8H2O
NH4Cl+AgCNO=AgCl↓+NH4CNO
2S2Cl2+2H2O=3S+SO2↑+4HCl
H2S3O6 +4Cl2 +6H2O === 3H2SO4 + 8HCl
SF4 + H2O =SOF2 + 2HF
na2so4+o2+h2o=不反应

na2so4+h2so4 = 不反应
4H2O2 + H2Cr2O7=2CrO5 + 5H2O
Cl2O+H2O=2HClO

Cl2O6+2KOH = KClO3+KClO4+H2O

NaClO+2NH3===N2H4+NaCl+H2O
11P+15CuSO4+24H2O=5Cu3P+6H3PO4+15H2SO4
Ca3P2+6H2O=3Ca(OH)2+2PH3↑
PH4I+NaOH===NaI+H2O+PH3↑
PCl5+4H2O=H3PO4+5HCl

POCl3+3H2O=H3PO4+3HCl
2As+5NaClO+6NaOH=== 2Na3AsO4 + 5NaCl+3H2O
K2CO3+Al2O3=2KAlO2+CO2↑
sio2+co2+h20 = 不反应
Si+2HNO3+6HF=H2SiF6+2H2O+2NO2+H2↑

Answer 2

2KMnO4+16HCl=2MnCl2+5Cl2+2KCl+8H2O NH4Cl+AgCNO=NH4CNO+AgCl S2Cl2+H2O=SO2+S +HCl Cl2+H2O==HCl+HClO

SO2+HF=SF+H2O Na2S2O5 + H2O = 2NaHSO3 Na2SO3+H2SO4=Na2SO4+SO2+H2O

Answer 3

2KMnO4+16HCl=2MnCl2+5Cl2+2KCl+8H2O NH4Cl+AgCNO=NH4CNO+AgCl S2Cl2+H2O=SO2+S +HCl Cl2+H2O==HCl+HClO

SO2+HF=SF+H2O Na2S2O5 + H2O = 2NaHSO3 Na2SO3+H2SO4=Na2SO4+SO2+H2O
