C6H6 + 3H2 = C6H12
2C6H6 + 15O2 = 12CO3 + 6H2O
C6H6 + I2 = C6H5I + HI - условие - хлорид железа(III)
C6H6 + 3I2 = C6H6I6 - условие - свет
3 Na2CO3+2H3PO4=2Na3PO4+3CO2+3H2O
CuO+2HCl=CuCl2+H2O
2Fe(OH)3+3H2SO4= Fe2(SO4)3+6H2O
CaO+H2O=Ca(OH)2
CuCl2+2NaOH= Cu(OH)2+2NaCl
BaCl2+H2SO4=BaSO4+2HCl
Na2SO4+BaCl2=2NaCl+BaSO4
HNO3 + NaOH = NaNO3 + H2O
Al(OH)3 + 3NaOH = Na3[Al(OH)6]
CaC+2H2O=Ca(OH)2+C2H2
C2H2+2CL2=Cl2HC-CHCL2
