Sabstance AHI Jmal3(-03 Fe2Os(s) -825.5 CO(g) Fe(s) CO2 -110.5 0 -393.5 -aS (4 pts) 5. 2.56 g of sulfur was burned in a bomb calorimeter wi increased from 21.25 °C to 26.72 °C. The bo amount of heat produced per mole of SO; formed for the following reaction. th excess O2(g). The te eces y of 925 mperature 23 JrC. Calculate the mb calorimeter has a heat capacity of 9 quantty.of beat 9a3 (asls.47) 14 ·003a RbOH (aq) is mixed with 100.0 ml of 0.400 M HBr (aq) in a coffee cug f the two solutions was 24.40°C before mixing, and the ny change (AH) for the reaction in kilo joules per mExplanation / Answer
Q = m*C*dT
m = mass
C= heat capacity
dT = temperature change
Q = 2.56*923*(26.72 - 21.25) = 12.925 KJ
1 mole of S forms 1 mole of SO2
Moles of S = 2.56 / 32 = 0.08
Amount of heat produced per mole of SO2 = 12.925 / 0.08 = 161.5625 KJ
