I think the answer might be 51.14% since the formula had to equal a 100% just add 41.86 and 6.98 and subtract the sum to 100.
Since it was specifically stated that heat is released, therefore
heat is located on the right side of the reaction equation. Also stating the
states of each compound, the complete balanced reaction would be:
C2H5OH (l) + 3 02 (g) -----> 2 CO2 (g) + 3 H2O (g) + 1235
kJ
False. Chemical products are on the right side.
