Write the reaction equation: C2H6 → CO2 → C6H12O6 → C2H5OH → CH3COH → CH3COOH → (CH3COO) 2Ca

C2H6 + 7O2 => 2CO2 ↑ + 3H2O;
6CO2 + 6H2O = (photosynthesis) => C6H12O6 + 6O2 ↑;
C6H12O6 = (alcoholic fermentation) => 2C2H5OH + 2CO2 ↑;
C2H5OH + CuO => CH3COH + Cu ↓ + H2O;
CH3COH + 2Cu (OH) 2 => CH3COOH + Cu2O ↓ + 2H2O;
2CH3COOH + Ca => Ca (COO) 2 + H2 ↑.
