Upon heating, baking soda decomposes as follows, creating the holes in baked bread: 2NaHCO3(s) - NaCO3(s) + CO2(8) +H20(1) 1st attempt Jul See Periodic Table See HD When 40.0 g NaHCO3 decomposes, the change in energy is-30.8 kJ. Use this information and the additional information provided to calculate the AH, of NaHCO3. AH(kJ/mol) -286 Substance H2001 CO2(8) Na2CO3(s) -394 -1131 AH, of NaHCO3 kJ/mol 15 OF 23 QUESTIONS COMPLETED < 22/23 > SUOM
Baking soda decomposes on heating as follows, creating the holes in baked bread: 2NaHCO3(s) — Na,CO() + CO2(g) +H,0(1) AH --129.3 kJ 1st attempt Il See Periodic Table O See Hint Calculate the standard molar enthalpy of formation of NaHCO3(s) from the enthalpy of the baking soda decomposition reaction and the following information: AH9 [Na2CO3(s)] - -1131kJ AHCO2(g)] = -394 kJ AH9 [H2000) = -286 kJ Standard molar enthalpy:
Upon heating, baking soda decomposes as follows, creating the holes in baked bread: 2NaHCO3(s) > Na,CO3(s) + CO2(g) +H,0(1) 4th attempt Feedback W See Periodic Table D See Hint When 35.5 g NaHCO3 decomposes, the change in energy is-27.3 kJ. Use this information and the additional information provided to calculate the AHF of NaHCO3. Substance H20(1) CO2(g) Na2CO3(s) AH (kJ/mol) -286 -394 - 1131 AH f of NaHCO3-937 kJ/mol
