Take a look at the thermochemical equation for the combustion of hexene gas shown below. If the reaction is conducted in a calorimeter containing 445 mL of water at 19 degrees celsius (initially) and a total of 7.4 grams of hexene (C6H12) is combusted, what will the final temperature of the water be? Assume the density of water is 1 g/mL and the specific heat capacity of water is 4.18 J/gC. Round your answer to 2 decimal places, if necessary. Do not include units in your final answer. C6H12(g) + 9O2(g) --> 6H2O(g) + 6CO2(g)
Hcombustion = -432.09kJ/mol

the answer is 0.8m.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

i believe the answer is 5,000
