Write the chemical equation$($s$)$ ffr Sacchariffcation process: conversion of starch $($C$6$H$100$s$)7$ maltose $($C$12$H$22011)$ and Fermentation process: conversion of maltose $($C$12$H$22011)7$ glucose $($C$6$H$1206)7$ ethanol $($C$2$HsOH$),$ respectively.

$($b$)$ Com ffom Hong Kong contains $55\%$ of starch, $15\%$ of starch is consumed in the ffrmation of byproducts during the ffrmentation and the rest $85\%$ of starch is converted into ethanol. Determine the weight of com in kilogram is needed in order to produce one liter of ethanol?

$($Molar mass: Carbon C $=12$ g$/$mol$,$ Hydrogen H $=1$ g$/$mol and Oxygen O $=16$ g$/$mol; density of ethanol at $25$C $=783\mathrm{.}924$ kg$/$m$3)$
