Alerta ...... (para lapso (erro !!!!... :-) ) nos primeiros 6 minutos da aula...
A fórmula estrutural do ácido benzóico está correta!
A fórmula molecular escrita no quadro (C6H6O2) está errada !!
Corrigir para ácido benzóico : C7H6O2
Corrigir o acerto da equação em conformidade.
C7H6O2 (cr) + 15/2 O2 (g) ---> 7CO2 (g) + 3H2O (l)INSTRUMENTATION:
Ballistic Combustion Bomb Gallenkamp
KEYSIGHT Digital Multimeters 34461A 6 ½THERMOCOUPLE type K
The Type K thermocouple (chromel -alumel)
Type K Accuracy (whichever is greater):
Standard: +/- 2.2C or +/- .75%; Special Limits of Error: +/- 1.1C or 0.4%
Calibration Experiment ....Screen Shot
Naphthalene Experiment ....Screen Shot
The quantity of energy evolved by combustion of SRM 39j, benzoic acid, when burned under the standard bomb conditions is given below, where g is the gram mass (mass in vacuum). The reduction of weight in air to mass in vacuum was made using the value 1.320 g·cm-3 for the density of benzoic acid at 25 °C.
Certified Value: 26 434 ± 3 J/g
C7H6O2 (cr) + 15/2 O2 (g) ---> 7CO2 (g) + 3H2O (l)
E (J/K) = 26 434 x m(AB) / Δ T (AB)
m(AB) – Experimental mass of benzoic acid (gram)
Δ T (AB) – Temperature change of the calibration experiment
Naphthalene
C10H8 (cr) + 12 O2 (g) ---> 10 CO2 (g) + 4 H2O (l)
u (naf) = - <E> (J/K) x Δ T (naf) / m(naf)
m(naf) – Experimental mass of naphthalene (gram)
Δ T (naf) – Temperature change of the sample experiment
Δ Um = u (naf) x MM (naf) ; Δ Hm = Δ Um + Δ n (g).RT
Δ n = n[CO2 (g)] - n[O2 (g)] = 10 - 12 = - 2 mol
