Упражнение 2. Химические свойства простых веществ.
2.1. Ge + О2 =
2.2. Si + О2 =
2.3. Sn + Cl2 =
2.4. Pb + HCl =
2.5. Si + NaOH =
2.6. Ge + S =
2.7. Pb + С =

Answer 1

2.1. Ge + О2 = GeO2
2.2. Si + О2 = SiO2
2.3. Sn + Cl2 = SnCl2
2.4. Pb + HCl = PbCl2 + H2
2.5. Si + NaOH = Na2SiO3 + H2O
2.6. Ge + S = GeS
2.7. Pb + С = PbC2
