Styrene, CgHg, is one of the substances used in the production of synthetic rubber. When styrene burns in oxygen to form carbon dioxide and liquid water under standard-state conditions at 25°C, 42.15 kJ are released per gram of styrene. Find the standard enthalpy of formation of styrene at 25°C, AH" (C02(9)) = -393.5 kJ/mol, AH®:(H,0(I) = -285.8 kJ/mol Select one: a. - 4390 kJ/mol b.-1044 kJ/mol c. -8681 kJ/mol d. +99 kJ/mol O e. +637 kJ/mol The heat of solution...
