1)Расставить коэффициенты P  + Сl2  → PСl5
B  + P2O5  → P4  + B2O3
P4 + O2 = P2O5
P4 + NaOH + H2O = PH3 + NaH2PO2
  P4 + Na = Na2P16
Si + F2 = SiF4
Ge + HNO3 (конц) = GeO2 + NO2 +H2O Sn + KOH + H2O = K2[Sn(OH)6] + H2

SiO2 + C = CO + Si
PbS + O2 = PbO + SO2
Cl2 + Sb = SbCl5 Br2 + H2 = HBr
F2 + H2O = HF + O2
KMnO4  + HCl  + KCl = K3MnCl6 + Cl2 + H2O
HF + SiO2 = SiF4↑ + H2O
Ti + HCl = TiCl3 + H2
Ti + KOH + H2O = K2TiO3 + H2
Ti + S = Ti2S3
FeTiO3 + C + Cl2 = TiCl4 + FeCl3 + CO  (не указывать тип реакции)
TiCl4 + Mg = Ti + MgCl2​
