Đáp án:
Giải thích các bước giải:
-5 PTHH về axit axetic:
$CH_{3}COOH+NaOH→CH_{3}COONa+H_{2}O$
$2CH_{3}COOH+2Na→2CH_{3}COONa+H_{2}$
$CH_{3}COOH+C_{2}H_{5}OH→CH_{3}COOC_{2}H_{5}+H_{2}O$
$CH_{3}COOH+Na_{2}O→CH_{3}COONa+H_{2}O$
$CH_{3}COOH+Na_{2}CO_{3}→CH_{3}COONa+CO_{2}+H_{2}O$
-5 PTHH về rượu etylic:
$C_{2}H_{5}OH+3O_{2}→2CO_{2}+3H_{2}O$
$2C_{2}H_{5}OH+2Na→2C_{2}H_{5}ONa+H_{2}$
$C_{2}H_{5}OH+CuO→CH_{3}CHO+Cu+H_{2}O$
$CH_{3}COOH+C_{2}H_{5}OH→CH_{3}COOC_{2}H_{5}+H_{2}O$
$C_{2}H_{5}OH\xrightarrow{t^o,xt}C_{2}H_{4}+H_{2}O$
