Đáp án:

 `↓`

Giải thích các bước giải:

`a)`

`CH_3COONa + NaOH` $\xrightarrow[]{t^0,CaO}$ `CH_4↑ + Na_2CO_3` $$$$

`CH_4 + Cl_2` $\xrightarrow[]{as,1:1}$ `CH_3Cl + HCl`$$$$

`CH_3Cl + Cl_2` $\xrightarrow[]{ánh sáng}$ `CH_2Cl_2↑ + HCl`$$$$

`b)`$$$$

`CaC_2 + 2H_2O -> C_2H_2 + Ca(OH)_2`$$$$

`C_2H_2 + H_2` $\xrightarrow[]{t^0,xt,Pd}$ `C_2H_4`$$$$

`C_2H_4 + H_2` $\xrightarrow[]{t^0,xt,Ni}$ `C_2H_6↑`$$$$

`C_2H_6 + Cl_2` $\xrightarrow[]{Ánh sáng}$ `HCl + C_2H_5Cl`$$$$
