The reason for this, is that un-branched 2023-11-25.This particular isomer is the standard 100 point on the octane rating scale (the zero point is n-heptane). 2C_8H_18 + 25O_2 -> 16CO_2 + 18H_2O We begin by balancing the C and the H atoms first, C_8H_18 + O_2 -> 8CO_2 + 9H_2O Now, counting the number of O atoms on either side; "reactant side" -> 2 "product side "-> 25 So, C_8H_18 + 25/2O_2 -> 8CO_2 + 9H_2O Find step-by-step Chemistry solutions and your answer to the following textbook question: For a particular isomer of C8H18, the following reaction produces 5113. Average mass 114.0587molKCIO 3 = 744kJ molKCIO 3.0°C and a pressure of 1. 2,2-Dimethylhexane. 4. Description.
