Giải giúp em với ạ

Đáp án:

1) $C_6H_{12}O_6+H_2\xrightarrow{{Ni, t^o}} C_6H_{14}O_6$ 

2) $C_6H_{12}O_6\xrightarrow{{\text{lên men rượu}}} 2CO_2+2C_2H_5OH$ 

3) $C_5H_{11}O_5CHO+Br_2+H_2O\to C_5H_{11}O_5COOH+2HBr$ 

4) $C_{12}H_{22}O_{11}+H_2O\xrightarrow{{\text{enzim}/H^+}} C_6H_{12}O_6+C_6H_{12}O_6$ 

5) $(\kern-6pt-C_6H_{10}O_5-\kern-6pt)_n+nH_2O\xrightarrow{{\text{enzim}/H^+}} nC_6H_{12}O_6$ 

6) $[C_6H_7O_2(OH)_3]_n+3nHNO_3\xrightarrow{{H_2SO_4 đ, t^o}} [C_6H_7O_2(ONO_2)_3]_n+3nH_2O$ 

7) $C_n(H_2O)_m+nO_2\xrightarrow{{t^o}} nCO_2+mH_2O$ 

Đốt cháy mọi cacbohidrat ta luôn có $n_{O_2}=n_{CO_2}$
