WebDraw a balloon with a pair of nitrogen atoms and three pairs of hydrogen atoms floating inside. This yields a balloon with two molecules, each with one nitrogen atom and two hydrogen atoms. W is positive because the volume is condensing. Consider the following reaction: 2Al (s)+3Cl2 (g)=2AlCl3 (s); deltaH=-1390.81 kJ. WebStep 1 Write the formula for delta H Delta H = n x delta H CO2 …. Use this value, along with the standard enthalpies of formation of C_2 (g) and H_2 0 (l), to calculate the enthalpy of formation of indene, in kJ/mol. Delta_f H^degree for CO_2 (g) and H_2 0 (l) are -393.509 kJ/mol and -285.83 kJ/mol respectively. Enthalpy of formation = kJ/mol.
