<u>Answer:</u> Maximum work that can be obtained by given amount of methanol is -343kJ.
<u>Explanation:</u>
For the given chemical reaction:
By Stoichiometry of the reaction:
2 moles of methanol does a work of 1372 kJ.
So, 0.5 moles of methanol will do a work of = 
Hence, maximum work that can be obtained by given amount of methanol is -343kJ.
When q is the heat energy in joules (J)
so, according to this formula, we can get q (in joule unit):
q = M*C*ΔT
when M is the mass of the water sample = 1.85 g
C is the specific heat capacity of water = 4.18 J/g.°C
and Δ T is the difference in temperature (Tf-Ti) = 33 - 22 = 11°C
So, by substitution, we will get the value of q ( in Joule):
∴ q = 1.85 g * 4.18 J/g.°C * 11 °C
= 85 J
Answer:
It comes from the chemical reaction of The wax and the gas because the wax is made up of carbon-based chemicals so the gas and carbon make the candle light =)
