a) CH3COONa + NaOH\(\xrightarrow[t]{CaO}\) CH4 + Na2CO3
CH4+ Cl2 -> CHCl3 +HCl
b) C4H10 \(\xrightarrow[xt]{t}C_3H_6+CH_4\)
CH4 + O2-> CO2 +H2O
CO2 +Ca(OH)2-> CaCO3 +H2O
C) Al4C3 + H2O -> Al(OH)3 + CH4
CH4 \(\xrightarrow[lamlanhnhanh]{1500^0}\) C2H2 +H2

Giải thích các bước giải:
Ca3(PO4)2 + 5C+ 3SiO2 --> 5CO + 2P + 3CaSiO3
P +O2--> P2O5
P2O5 + 3H2O --> 2H3PO4
H3PO4 + 3NH3 --> (NH4)3PO4
2(NH4)3PO4+H2SO4( đặc) --> 3(NH4)2SO4+ 2H3PO4
2H3PO4+ 3CaS --> Ca3(PO4)2 + 3H2S
\(C_4H_{10}\rightarrow C_3H_6+CH_4\)
\(C_3H_6+H_2O\rightarrow C_3H_7OH\)
\(C_3H_7OH\rightarrow C_3H_6+H_2O\)
\(C_3H_6+CH_4\rightarrow C_4H_{10}\)
\(C_4H_{10}\rightarrow C_2H_4+C_2H_6\)
\(2C_2H_4\rightarrow\left(-CH_2-CH_2\right)_n\)
