Using the following equation for the combustion of octane, calculate the heat associated combustion of 100.0 g of octane assuming complete combustion. The molar mass of octane is 114.33 g/mole. The molar mass of oxygen is 31.9988 g/mole.2C8H18+25O2→16CO2+18H2O;ΔH∘r xn = -11018 kJA. -11018 kJB. -4819 kJC. -602.3 kJD. -535.4 kJE. -385.5 kJ

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
