Answer:
Alcohol is a byproduct of the fermentation process, which takes place when the yeast converts the sugars derived from the grain. Knowing that, you can increase the alcohol by volume (ABV) by increasing the size of the grain bill or increasing the amount of malt extract used.
A) 4400 kj of heat released into surroundings
<h3>Further explanation</h3>
Reaction
C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O, the ∆H is –2200 kJ
Reaction exothermic( ∆H=-, released heat to surrounding) and for combustion of 1 mole of C3H8
So for two moles of C3H8, the enthalpy :
