The combustion of hexane is given by the following reaction. 2 c6h14 + 19 o2 12 co2 + 14 h2o the enthalpy of reaction is −4163.0 kj/mol. how much energy (in joules) will be released if 62.30 grams of hexane is burned. (molar mass of hexane = 86.20 g/mol).

3'008,757.5 Joules

Explanation:

First, calculate the hexane (Hx) moles:

Then, multiply the number of moles by the enthalpy of reaction (the enthalpy of reaction is given by mole of reactant):

Change to Joules:

It has negative sign due to its released energy, so the answer should be positive: 3'008,757.5 J

i have no clue hope you find the answer
