Question

Помогите решить 5 задание

Answer 1

2CH4=C2H2(x1- ацетилен)+3H2 (t=1500)
2C2H2+5O2=4CO2+2H2O (t)
2CO2избыток+Ca(OH)2+=Ca(HCO3)2
CH4=C+2H2(x2-водород) (t)
2H2+O2=2H2O  (t)
2Na(x3-натрий)+2H2O=2NaOH+H2
б)CH4=C+2H2 (t=1000)
C+2H2=CH4 (t)
CH4+Br2=CH3Br+HBr (УФС)

Answer 2

а)
CH4=C+2H2
C+O2=CO2
CaCO3+H2O+CO2=Ca(HCO3)2
2CH4=C2H2+3H2
2C2H2+5O2=4CO2+2H2O
2H2O+2Na=2NaOH+H2
б)
CH4=C+2H2
C+2H2=CH4
CH4+Br2=CH3Br+HBr
