Câu 7:
a,
Thuỷ phân saccarozơ:
$C_{12}H_{22}O_{11}+H_2O\xrightarrow{{H^+, t^o}} C_6H_{12}O_6$ (glucozơ) $+C_6H_{12}O_6$ (fructozơ)
Thuỷ phân tinh bột, xenlulozơ:
$(C_6H_{10}O_5)_n+nH_2O\xrightarrow{{H^+,t^o}} nC_6H_{12}O_6$ (glucozơ)
b,
$(C_6H_{10}O_5)_n+nH_2O\xrightarrow{{H^+,t^o}} nC_6H_{12}O_6$ (glucozơ)
$C_6H_{12}O_6+2AgNO_3+3NH_3+H_2O\to CH_2OH[CHOH]_4COONH_4+2Ag+2NH_4NO_3$
c,
$(C_6H_7O_2(OH)_3)_n+3nHNO_3\xrightarrow{{H_2SO_4, t^o}} (C_6H_7O_2(ONO_2)_3)_n+3nH_2O$
