Solve the given problem. Have your solutions as an attachment (15 points).Given below are the standard enthalpies of formation of liquid hexene and oxygen gas included in this chemical equation,C6H12 (l) + 9O2 (g) → 6CO2 (g) + 6H2O (l).Compute for the enthalpy changes of reaction of the given chemical reaction and identify what kind of thermochemical reaction it is.

Determine the enthalpy change for 7.1 g of C6H6 in the following reaction using the enthalpies of formation. (5 marks) 2C6H6 (l) + 15O2(g) 12CO2(g) + 6H2O(g)

Question 16Calculate the standard enthalpy of combustion for the following reaction:C6H12O6(s) + 6O2(g) --> 6CO2(g) + 6H2O(l)

At constant pressure, the combustion of 5.00 g of C2H6(g) releases 259 kJ of heat. What is ΔH for the reaction given below? 2 C2H6(g) + 7 O2(g)–> 4 CO2(g) + 6 H2O(l). Hint: Convert 5.0 grams to moles (divide by molar mass).  Divide 259 kJ by your answer to get kJ/mole reacted.  Next, multiply by 2 since there are 2 C2H6(g) in the balanced reaction. Group of answer choices1800 kJ3108 kJ5168 kJ2155 kJ

Calculate the amount of heat needed to boil 65.8g of hexane (C6H14), beginning from a temperature of −3.3°C. Be sure your answer has a unit symbol and the correct number of significant digits.

A thermochemical equation is an equation which shows the heat involved in the process (the heat released or absorbed when a reaction takes place). Give the thermochemical equation for the combustion of benzene below.C6H6 (l) + 7½ O2 (g) —> 3 H2O (l ) + 6 CO2 (g)                 ΔH = - 3269 kJ*3 pointsC6H6 (l) + 7 ½ O2 (g) —> 3 H2O (l ) + 6 CO2 (g) - 3269 kJC6H6 (l) + 7 ½ O2 (g) —> 3 H2O (l ) + 6 CO2 (g) + 3269 kJC6H6 (l) + 7 ½ O2 (g) - 3269 kJ —> 3 H2O (l ) + 6 CO2 (g)C6H6 (l) + 7 ½ O2 (g) + 3269 kJ —> 3 H2O (l ) + 6 CO2 (g)
