CaCO3 = CaO + CO2
CaO + 3C = CaC2 + CO
CaC2 + 2H2O = C2H2 + Ca(OH)2
C2H2 + H2O = CH3COH
CH3COH + 2Cu(OH)2 = CH3COOH + Cu2O + 2H2O
CH3COOH + CH3CH2CH2OH = CH3COOCH2CH2CH3 + H2O
2CH4 = C2H2 + 3H2
C2H2 + HCl → CH2=CHCl
n(CH2=CHCl) → (-CH2-CHCl-)n
2CH4 = C2H2 + 3H2
3C2H2 = C6H6
C6H6 + Br2 →(AlBr3)→ C6H5Br + HBr
C6H5Br + H2O → C6H5OH + HBr
а) 2KMnO4 (нагрев)--> K2MnO4 + MnO2 + O2
O2+H2=H2O2
2H2O=2H2+O2
б)O2+Mg=MgO
думаю так......
